Cyclemax has them at a pretty good price: GL1500 Compu-Fire Alternator. It comes with everything you will need - all you need are the tools and the time to take the old one out and put the new one in.

Have you considered Ken Hemming offerings? http://myplace.frontier.com/~hemi-roid/. I have heard nothing but praise for his quality of work, and his quality of service.

You might note that if you get a Compu-Fire, then you may need a "sealed" battery as recommended at their site. For all 'high output' alternators, you should also consider the rest of the electrics eg fuses, wires, and battery.

Those are the best 2 choices....Just choose one...
CycleMax is excellent and has good prices..
Ken has done many of these for Wing riders over on the GWRRA board.

Try Niehaus cycle sales. That is where I got mine from. Easy to fit and you will need a sealed battery.

what would need to be addressed with a bigger alternator as far as the electronics are considered? i've noticed on mine that when i apply the brakes,the head ligts dim slightly,or is that normal?

With my Compufire my lights never dim, even when I am running all my electrics AND Driving lights....In fact the Compufire will charge at idle even with these pulgged in... Driving lights, electric jacket, GPS, and all the bikes current draw, the volts never drop below 13.9 and usually stay at 14.1 to 14.4 ...I also have an AGM battery installed...

Just what they suggest - additional (larger) master fuse, and AGM battery. Other than that, nothing else needs to be changed.

I bought and installed my Compufire 5 or 6 years ago and didn't change a thing, other than the battery was replaced with a sealed unit. I have had no electronic issues whatsoever. I didn't even need to change any fuses. I ride a '93 Aspencade.

Because the Compufire can put out so much more current, the main fuse should be changed to the ones that come with the kit. It won't hurt anything if you don't, but you'll be limited to the 55 amp capacity of the original fuse, instead of the 90 amps the Compufire can actually supply.

If you haven't had a problem, you haven't "needed" the additional current.

There was a bag with a couple stickers and two dogbone fuses included with my Compu-Fire when I got it.

Why do you need a sealed battery with a Compufire alternator? My 96 Aspy had the Compufire Alt. and Compufire Batt. when I purchased it 4 years ago. Battery finally gave it up this year and I replaced it with a standard acid battery. Have had no problems as of yet, approx. 1000 miles. Should I expect future problems with this set up? Am leaving on Arkansas trip in couple of weeks and don't want any mechanical problems to come up.

Thanks for any help.

not positive but i believe that the bigger alternator could "boil" the the battery and cause it to run low on the acid. and the last thing you want is to have battery acid getting on anything on your bike,would not be a good thing. a low battery shortens the life of it also. their will be more responces soon on your question.

The larger alternator will likely not boil the battery, but a bad regulator surely can.

The Compufire's voltage regulator is set a little bit above the normal voltage. That is because the AGM has a slightly higher normal voltage. From the Compufire web site:

Compu-Fire Sealed Battery

The Compu-Fire sealed battery is maintenance free, operates at an average of 0.5 to 0.75 volts higher than the original and provides 40 extra cold cranking amps. Starting is now crisper, ignition is stronger and lights are brighter. Goldwing riders can now operate high power accessories with complete peace of mind and eliminate carrying extra batteries!


That higher voltage will boil the electrolyte out of a standard lead acid battery. Combined with the higher amperage capability of the Compufire alternator, the standard battery will sulfate very quickly.
