    Anyone know of a good wiring diagram for a flathead 12volt conversion w/alternator? I'm having a charging problem, which I think is simply due to me wiring something incorrectly. Thanks!

    If you have a one wire its run right to soldinode terminal battery side.If you have reg type alt you need a 4 terminal regulater.

    The GM alternator is easily converted to a single wire item,..Go for that, easy, and fewer connections, neater looking. Or, powermaster make one that looks like the old timey generator...I'll let you know how that works,...I just installed mine.
