I have a CompuFire alternator on my 88 GL1500... The bike has approx 16 LED ambient lighting, a 4 LED rear brake light under the wing, all the standard bulbs and lighting on the rest of the bike.

My question is, how much load can the CompuFire really take?
I was wanting to add light housing's to the lower cornering lights, and run them as driving lights... mainly for visibility for the cagers. I have a couple 55 watt light housings that were pulled from another vehicle I want to use. Would this put too much load on the alt?

As of now, sitting at idle with everything including the LED's, I get a nice reading of 13.8-14.0 volts.


The lower corner lights had already been wired to run as driving lights, on a switch, but the PO pulled the housings on both sides.....

Put them on and run them. The Compufire will handle them with no problems. The led's hardly draw anything and with everything else being standard lighting you'll still have power to spare.

The CompuFire can produce about 1200 watts.
Your bike stock runs about 200 watts before you add anything.

I wouldn't worry too much about it yet if I were you.

Sweet! Thats what I was hoping for...

Thanks guys!

Hey Rudy,
Lets see if I can keep up with you.
Watts = Voltage x Amps
Amps = 55 watt lights / 12 volt system
In otherwords, with a potential of a 90 amp charging system, the lights should pull maybe 4.6 amps.

Yes, that be right with 12.0 volts as the figure, but they should be rated at 13.6 for the 55 watts or about 4.04 amps.

A = 55W / 13.6V or 4.04 amps

either way, the Compufire has more than enough to run a gaggle of driving lights.

Per lamp, yes.
