Compu-Fire alternator for GL1500

I bought one of these in September 2015 and it ran great till last weekend when my bike died on me and left me sitting on the side of the road for 2 and half hours waiting for a tow truck. At first I thought it might have been my battery that was the problem as it was 3 years old at the time when I replaced to stock Honda alternator for this one. After buying a new battery for my bike on Monday 28/11/2016 I thought everything was good again only to have the bike die 2 days later and waiting again for another tow home. Not a happy Goldwing rider and I wish I had seen the other review before buy it now as I would have bought a stock Honda one instead.

Compu-Fire alternator for GL1500

I have now had two Compufires in my 1500's and both failed within two years of installation. Both were repaired at a local shop as Compu-fire is no help. One has failed again and am now back to purchasing OEM units. Don't wast your money on the chineese models either. I figured that the heavier duty unit would last longer but not likely.

Failed after 3 years

I purchased one in 2010 and in 2013 (about 15,000 miles later) it failed leaving me stranded on the side of the highway. I reinstalled the OEM alternator and I was back on the road. I have tried to contact Compu-Fire 6 times. 3 by phone and 3 by email. They have not called or written me back.

I've been working on repairing it. Looks like it's made from a Delco CS-121D alternator used on 2000 or so Saturn SC vehicles. I've troubleshot it to the voltage regulator.

For the cost I am disappointed in the lack of customer support from Compu-Fire.

I don't often leave reviews but did feel it is important that other riders know Compu-Fire does not seem to stand behind their product.

Simply fantastic!

I installed the Compufire on my GL1500 a couple weeks ago. What a difference! I have extra trunk and saddle bag lights added, the fog lights are on all the time as well as extra lights on the back of the trunk. When my wife and I would cruise with our heated vests one time, the engine stalled - batterie drained. With the Compufire, I can have everything plugged in and still show 14.6 Volts AT IDLE!!! When I hit the brakes, the headlight doesn't even dim anymore! - Problems solved. Now I will be able to add a trailer with power to spare.
