Everything worked great once I figured out what out of 3 spacers u needed. Of course it was the third try for me. I called for help and compu-fire didn’t even now what I was talking about.
Great product comes with everything you need for installation
Excellent!!

Install went well. Bike now charges at idle. Great product. I recommend it.
Has worked good so far. Maybe should have been a 45 amp instead of a 40 as my bike is a Electra Glide Classic although it is carbureted.
