40 Amp Harley Charging System Kit.
Ordered the kit even though after replacing , it looks like the only thing that was bad was the voltage regulator. Was a little concerned with the look of the voltage regulator on the front since its shaped different than the Harley OEM. After I got it on, it didn't look to bad and the performance was instantly noticeable. Best to do the kit because if one thing goes, its a matter of time before the others go, including the battery.

I have waited to review this until now. Installed the unit 08/10/2020 have over 2000 miles on Harley and no problems. The Compu-Fire 3 is very well made and I was impressed with how heavy duty it is. Two Thumbs UP!!
