Electrical Question

[Cruzr Joe]

2013 RT. i have installed a USB socket in the space that is normally used for a analog fuel gauge. I need to know if i can use the wiring from the fuel gauge to hook up the USB charging unit. If so what wires would i use ? the USB has a red (hot) wire and a Black ( ground ) wire. :dontknow::dontknow::dontknow:

UPDATE, Thanks all, it works

well 12 people have read this and still nobody knows the answer, I am not leaving without an answer. :helpsmilie:

My suggestion is to find another power source (like to the fuse box or the battery). I'm not sure if the cords on the gauges can deliver enough power to charge up a cellphone... Do you have a tester?

Does the guage have backlighting? If so im betting you can pull that tiny amont of power from it. I will look at the schematic tonight and see if I can tell.

Instructions

Didn't come with instruction?

Assuming that the manufacturer used standard color coding protocol. Red would be positive and black would be ground or negative.

We all know how to break the word "assume" down, don't we?

If all else fails go back to the manufacturer of the port!

The amount of current drawn by a cellphone in the charging mode is in the milliamperes range. Probably less the a 194 light bulb!

Good observation, that is why i post questions here so i can get intelligent (had to use the spell checker on that one) responses. yes i have a tester but not real knowledgeable on specs other than is it hot or not.

I know someone out there has the answer ............ HELLO OUT THERE, ANYBODY HOME? :dontknow::dontknow:

Thanks, i anxiously await your response, yes the gauge did have back lighting (i think)

No problem with the port, just not sure if the Spyder will like it and if so which wires will connect.

A USB style charging port provides +5 Volts DC to devices which have a USB input. As I'm sure you know the voltage the Spyder provides is +12 Volts DC. If the charging port you have is designed to convert the Spyder's 12 volts to 5 volts then you're ok. I'm sure you already know this but I had to make sure because there are USB ports with direct wiring and 12 volts would fry a smart phone.

An analog fuel gauge would require at least a ground wire and a fuel sender wire. You could use the ground wire but not the fuel sender wire because it does not supply a steady source of 12 volts. If the fuel gauge also has a third wire for lighting you could use that provided you knew that when the lights were off the port would not work. The current requirements of a USB charger are modest so virtually any 12 volt source for the Spyder would do. If this were mine I would either take the time to install a separate fuse block if there was a need for more hookups in the future, or if not then I would tap the wire coming out of the Spyder's existing fuse block for the 3 amp unswitched accessory circuit. I'd find the color code for the wire from the schematics in the maintenance manual (this is easy) and then use a Positap connector.

I did exactly what you did. I used the power wire to the gauge, however I added an inline 3amp fuse. I would find a different 12v source if I was to do over again. I used it to power/charge the GoPro. Sold the camera and took the USB off.

I'd pick the voltage off of something else. Probably could find the frunk accessory power socket wire even if you don't have the accessory socket. The wire should be down on the left side below the headlight assembly. Just tap that and run up to your USB unit. It will take the current without any problem.

I just did this on my '12 RT-S. Sent you a PM.

By the wiring diagram the front and rear accessory plug are on the same circuit. You could tie into that circuit. If you have the plug in the front trunk splice into the wires. If you don't the unused connector should be there. If you use that for your power source you can make it switch or unswitched depending on which slot you put the fuse in.

I use the backlight lead and the ground lead to power my GPS - no problems with that. Another post mentioned that you need to ensure the conversion of the bike's 12VDC to the 5VDC needed for your USB devices.

I put a 12v cig marine lighter through my front right speaker grill. With that you can power a GPS or plug one of the many dual USB adapters that plug right into the lighter. At least you'd have several different varieties of electrical distribution. I run a dual USB adapter in my truck to power and charge both of our iPhones. That same charger would work on the bike as well.

Here's my install on that if you're interested. I should've shown you at SF this year.

Hi Kevin, I ordered the 12v cig marine lighter and fuze blk you used. I should've asked before ordering, was I supposed to order wire with it? If so, what guage of wire do I need and how much? Where did you get power for the fuze blk from? I'm not an electrician so this is very foreign to me. I'm going to use this to charge my IPhone. Thanks for your help.
