    Hey everyone I have a question, it may sound like a stupid question. However I am more familiar with fixing cars than bikes lol. Anyways I was told my voltage regulator on my 73 Iron/Shovelhead 1000 is shot. The one that is on it is after market. My system runs on a 12 volt generator system, not a stator. Can I use a voltage regulator off a bike that runs off of a stator, on my bike that runs off of a generator? Thanks!

    Nope, it won't work. The output of a generator is DC and the output of a stator is AC.

    Welcome to the forum Jimbo. Do a Google search "car voltage regulator on a harley". you will get a lot of info to sift through, and maybe find a less expensive regulator for your Ironhead.

    Thanks guys for suggestions, I replaced voltage regulator. However she is still not holding charge. It was a brand new regulator, battery and generator have tested out fine.........I am really stumped at this point, got anything else for me to try? Thanks~

    Using a meter, what voltage reading do you get when measured directly across the battery. Measure at both idle and at 2500 RPM.

    Have you load tested the battery and did you polarize the generator prior to start up, any time the battery is out of the loop you should do this http://i662.photobucket.com/albums/uu346/chopsgarage/PolarizeGenerator.jpg

    Did you polarize the generator as Jack mentioned in post #4?
