PC- 8 power Buss install from Eastern Beaver - Pictures included

So...

This was one of those projects that took too long.

Excuses as follows:

1. Winter
2. Back went out
3. Got sick
4. Scrapped the first wire harness I made and started over.
5. Work

However, now I'm laid off, and am catching up on a ton of stuff. Sorry for the long ramble here, but hopefully someone finds it useful.

I bought an Eastern Beaver PC-8 from http://easternbeaver.com/Main/Products/Fuseboxes/PC-8/pc-8.html It is a quality product, and does a simple task very well. You can cob together something similar, but after looking at what was available over the counter and other similar products on the web, I felt the PC-8 was the best for my application.

I decided not to order a pre-made harness from Eastern Beaver. I just didn't see how any of those lengths would potentially be perfect for anywhere I wanted to mount this. That said, Jim at Eastern Beaver is very responsive to email, and it only took a weeks shipping from Japan to receive everything. Jim can make you a custom harness using your measurements. If you don't mind paying a premium and you don't have your own crimper or care to own one, that is the way to go. For me, it was cheaper to do it myself, except that I had to buy a new crimper! ( the one I had for many years vaporized - watch it show up now ) I bought:

Eastern Beaver:
- The PC-8,which comes with the open barrel terminals you need, heat shrink, and fuses. These take care of everything only at the buss. You still need some of the stuff below.
- Various additional open barrel terminals I wanted for the install as well "mistakes"
- An open barrel crimper - Really cheesed as I "used" to have one. I ordered this one stateside for about $70... Very handy to have.
- Fuse holders... Can buy these anywhere, but his prices were in line.
- Some heat shrink tubing from him - Had some, but he had the type with the glue inside which is nice for some connections.
- Relays and relay sockets.
- Some weather proof switches... He has some really nice ones.
- Asst other stuff - I tend to order more than I need of anything... I don't like having to shop twice.

Home Depot:
- I picked up some 12 gauge high heat, and abrasion/oil resistant stranded wire in Black, Red, and Yellow.
- Bought some 16 gauge stranded wire in Black for additional ground. I grounded the relays with this one straight back to the battery, and then looped it back into the PC-8... Not really necessary, but insurance never hurt.
- Bought some 16 gauge stranded wire in Blue for the trigger wire.
- Bought some 18 gauge stranded wire in White for the garage door opener. Side project -Has nothing to do with the PC-8 as it is run by it's own battery. It is a 12volt battery, so I could hook it into the PC-8 if I didn't mind the constant, if minimal draw.

Radio Shack:
- Diodes for the triggers

Tools and stuff used: (Beyond the standard hand tools)

-Paladin Crimpall 8026 crimper with 2033 open barrel die for 12 to 22 AWG wires and connectors. This did the job fairly well. On the heavy brass ring terminals for the battery, I had to use a woodworking clamp to get a real solid crimp. Otherwise, it was as good a tool that I used to have.
http://shop.willyselectronics.com/b...r-open-barrel-terminals-12-22awg-/4,1211.html

- 33 watt soldering iron. Probably hotter than most need, but nice when you want to fully heat a terminal quickly.

- Electric Heat gun or propane wide flame torch for heat shrink. I used the Tyco wide flame I already had, but most can get away with a bic lighter. http://mediafilms.org/cpg_web/CPGI_137.pdf



I originally made a harness that I chose to route from the battery under the seat/frame over to the back fuse bar... However, that didn't work so well. My thought was to have the fuse holders in that cavity near the other fuses, but it was too tight in that area. The loom plus wires was just too thick for some spots.

I re-grouped and re-made/adjusted the harness to run from the battery along the same side of the bike in the little nook along the tank and the backbone of the frame. I put the main fuses in the battery bay.

Now... I'm using two power leads which is the reason for the yellow and red wires. I wanted to differentiate them so I knew which one was for the switched and un-switched/constant circuit. They are each on their own 30amp mini blade fuse... That gives me roughly 360 watts per feed, though I'll never touch that. They are mainly there in case I have a short to ground. The PC-8 will provide the proper fuse sizing per circuit.

I'm a bit anal. I used to work on electronics at the system board level and have trouble shot, repaired, and built many a wire harness. Every open barrel crimp connector was also soldered... this prevents oxidation/corrosion in case they ever get damp or wet. I soldered splices rather than use crimp connectors for the same reason and that is another good reason for using the glue infused heat shrink. I encapsulated the harness in a large diameter length of regular heat shrink and shrunk it down. Made for a nice, easy to handle harness and added a bit of additional abrasion and heat protection. I then placed that in plastic wire loom. Again, the last thing I want is a direct short to ground.

I placed the PC-8 on top of the back bone, but under the fake tank tupperware. It just barely fits under there. I am mounting it with 3M auto trim tape leaving enough extra wire to make adjustments or future repairs. As you can see in the photos below, I mounted the relays on the plastic pegs holding the under seat shielding to the frame... Worked perfectly. Some Spyder Lovers have placed theirs behind the cluster, and that is a good spot too. I wanted to keep that area uncluttered as I may add HID's and the ballasts will go up there. The PC-8 is still easily reached where I have installed it. Two plastic rivets and two torx screws. I don't expect to be in there much if at all.

One relay is for the switched circuits. The other relay is for my Motolights. I did not want the motolights on by default all the time, so I needed to leverage a second relay. It is still on the switched circuit side of the PC-8, but triggered via an illuminated switch. Tell you what... I'm glad I did this, as the install of the motolights that was done at the Gatlinburg rally wasn't really ideal. This cleaned things up quite a bit and now I never have to worry about all the crazy crimps from that install going bad.

Finally, I have a diode in line with the trigger to each relay. This prevents any voltage back feed from the relay frying the computer. Supposed to be a rare failure, but 50 cents for insurance made a lot of sense. Jim points this out and goes into more detail on his site here: http://easternbeaver.com/Main/Products/Fuseboxes/Wiring_Kits/Diode/diode.html

Circuit usage on my Spyder:

Switched - Powerlets in dash and Motolights. Moto lights use 100 watts, or 8.33 amps, so there is plenty of overhead considering I'll only be running a GPS and/or phone off of the powlets on this circuit.

Unswitched - 12volt digital voltmeter, and powerlet in Helibars.

* I've got the voltmeter running though a push button switch so it is not on all the time.

First... What the Eastern Beaver looks like (From Jim's site). Obviously one side is ground and the other is split between the 6 switched circuits (PWR on the board), and the two constant on circuits ( BAT on the board).

As you can see, I still have some tidying up to do. Tomorrow I finish installing my Helibar risers (write up coming on those), and wire in everything that is left and button her up. Then an oil change and some riding.

I also did the Garage door opener mod. I had a key chain door remote we don't use. So, I opened it up, removed one of the tactile button switches and soldered two wire leads to the board, then closed it back up after installing a new battery. I just used some velcro and stuck it up and out of the way behind the cluster. I used a momentary switch I bought from Jim@ Eastern Beaver to activate. I take pictures of where I put it tomorrow... Picture of the switch below... Really cheap, simple switch, and the boot anchoring it to the dash makes it weather proof... It also blends in with the dash so it isn't too obvious. Many thanks to those of you who already did this mod and gave me the idea too. More tomorrow in new thread.

Great mods and write up.

And a big :2thumbs: for Jim and Eastern Beaver. I love the products and the shipping time and customer service is awesome.
 
If you blow a fuse what do you have to take off to get at the PC-8?

Just the top Y panel which can be done with the Spyder's tool kit. Not hard to get at. Don't think it takes all that much longer than removing the cluster... and on the frame it is right under your nose and easy to see and handle.

The PC-8 doesn't have anything vital to running the Spyder hooked up to it... That may vary from owner to owner, but in most cases I don't think anyone would be on the side of the road changing a fuse unless they couldn't live for a bit without their GPS, radio, or something.

Maybe heated gear or juice box would make you want to address a blown fuse sooner than later. A lot of folks though run heated gear straight to the battery though and in this case, the PC-8 can handle the draw and is easier to get to than the battery bay.
 
I am looking at doing this to mine while I have everything off. I am just curious as to the purpose of having a relay for this setup. Maybe you can enlighten us?

It's a way to route the power so you won't need to run high amp to every switch. Also, you can hook the relay to be controlled by the switched circuit so the entire power block can be powered down 30 sec. after you turn off the key. This way you won't have to remember to turn off every appliance when you get off the bike or risking a dead batter when you return.

Under the Y panel is a great spot. I happened to put mine on the inside of the front frame directly behind the main wiring harness. I found these big patches of EZ-Pass mounting strips to hold my Blue Sea fuse block onto the frame. Zip tied it in a few places for insurance and piece of mind in case the adhesive came loose in the summer heat.

I tried to install my PC-8 under the Y panel last year. I did a dry run and it didn't fit; hmmmmmmmmmmmmmm, curious.

It fits. Though you have to get creative. It has to be perfectly positioned and that takes a bit of tinkering. Also.. Use carpet tape, not foam or velcro. Works just as well and keeps a lower profile. I also sanded the edges of my PC-8 a bit to ensure clearance, though I don't think I really needed to.

As noted by another member, the relay is for switching power on to the switched side of the PC-8 so that those terminals are energized when the bike is "on" and non-energized when the bike is "off". This way you ensure that there are no "vampire" loads on the bike when the ignition is off, and so that you don't forget to turn anything off. The PC-8 does have a couple of "always on" circuits. You would use these for anything that requires 24/7 power. A good example would be an alarm system. Why not just connect the alarm directly to the battery? A couple of reasons: Isolation and troubleshooting - The main reason I got a PC-8. Every non-factory accessory is routed through the PC-8 for it's power needs giving me one central power bus to trouble shoot electrical problems that may crop up, but also it prevents me from putting too much draw on some other part of the electrical bus on the Spyder. If I blow the fuse for the dash outlets I installed, then I know the problem is in that specific portion of my circuits or with the device plugged into the outlet. I don't have to scratch my head looking through a tangle of wires, or wonder if the problem is with the spyder or one of my mods. Have you ever really tried to get to the battery in a hurry, especially when you have hard cases/racks installed? It is not going to happen and that is another good reason for the PC-8. Granted, you still have to fuse the PC-8 itself back at the battery for safety in case those leads short against the frame in the future, but done right, you should almost never have to worry about that fuse blowing.

Relays are used for a number of reasons, and there are many kind of relays. For our purposes we are talking about general use 12volt 30 to 50 amp automotive style relays. You typically will tap into the 12v 3amp accessory lead for the trunk outlet to make the relay do it's magic for the PC-8 or even if you need to run a circuit like that and not use a PC-8.

View the PC-8 as the file cabinet for all your wiring. Helps keep everything organized and at a glance you can figure out what circuit is what. I've seen and worked on several spyders where the accessory wiring was a rat's nest of crimps, electrical tape, inline fuses, etc... All running in some random fashion, with no rhyme nor reason as to what was what....trouble shooting those bikes was a nightmare and cost hours in time in the garage or on the side of the road. The PC-8 doesn't necessarily cure that issue. ***BUT If you have a PC-8 and use some logic/brains in regard to how you route your wires, use the proper style of crimps and proper crimp tool, heat shrink, etc. then you will likely have very little to no problems ever when it come time to figure out a blown fuse or wiring issue.

I digress...and I have to go! As always, you can PM me about the PC-8 anytime.

Good write up and great product. I have the EVO one-- but really like the Eastern Beaver setup better and may switch to that someday.

I run my GPS, Radar Detector, Jammers, Tank Bag Charger, Mix-It audio and now Heated grip covers through mine.

Note---- if everything is wired correctly you shouldn't blow a fuse----virtually EVER.

As I read your post you sugest to take the power for the trigger lead to turn on and off the main relay to the PC-8 buss from the trunk 3 amp power plug. I thought that plug for aux power was hot all the time and not swithed.
I need a spot that I can cut into to have the curicut on only when the key is on. Any sugestions?

There are supposed to be two feeds for the trunk. One is switched with the ignition and one is always on.

On the 2008 GS the switched feed wire is purple with a yellow stripe. You can positap it towards the rear of the front factory fuse and relay box. That may be a different color on the 09's on up, so best bet it to look for the switched lead that should be tied up on the front of the Spyder somewhere on that side. -Or double check that your aux is really hot all the time.
