LED Digital Volt Meter for bikes

Heat causes batteries to lose charge more quickly, and excessive heat can damage batteries. Next mod:

Doc,

I like it, did you find a place that carries it in the US (website link)?

You might need that on your Iron Butt run!:spyder2:

I love this quote from the eBay ad (seller's in Singapore):

"Easily mounted anywhere on the dashboard or on the steering wheel"

I guess they dont have air bags in Singapore yet?

I thing you need the shadow Drag Speed Monitor Meter Speedometer Track! The way you just take off.... :roflblack:

I think the Volt meter is an excellent idea! I might just might get one, but I have other things to get first with my allowance. :spyder:

I fly electric R/C planes. There are a few volt indicators out there if you can't find these particular ones. Some can even display amps and watts.

And a very interesting discovery:
1. Idle with fog lights: 12.2 V
2. 7,000 RPM with fog lights: 12.5 V
3. Idle without fog lights: 13.4 V
4. 7,000 RPM without fog lights: 13.9 V

Interesting, indeed... particularly the 7,000 RPM numbers. I, too, run fog lights all of the time for visibility. I knew we were a little anemic on magneto output but still...

That says we basically have about 100-125w to use on our toys... I always figured we have maybe 200w.

Yeah, that is a bit disconcerting. Guess the fogs will go off if the heated gear is in use from here on out.

Are you measuring right at the battery terminals or somewhere in the harness?

 

[fastfraser]

Does this just hook up to battery terminals? and is there enough wire included.

Thanks for a reply.

Battery terminals.

Baterry terminals; plenty if wire.

I hope you have it on a switch.:shocked:

 

[docdoru]

No

 

[Lamonster]

No

I hope you keep your Spyder on a wall charger then.

I can see Doc riding down the road with a notepad and pen, writing the information down at every stoplight. Great info Doc......

 

[WackyDan]

Doc, you have HID headlamps and fogs...

And a very interesting discovery:
1. Idle with fog lights: 12.2 V
2. 7,000 RPM with fog lights: 12.5 V
3. Idle without fog lights: 13.4 V
4. 7,000 RPM without fog lights: 13.9 V

Mine with regular headlamps and fogs + moto lights...

So I broke out my multimeter and some alligator clips...

@idle
Headlights only - 13.7 volts
Headlights + Fog - 13.6 volts
Headlights + Fog + Motolights - 12.9 volts
Headlights + Moto only - 13.6 volts. - Which is odd.

@5500 RPM
All lights - 13.5

Obviously, two banks of HIDs draw more given Doc's findings...
