This is a 6 volt Autolite generator on my avatar Willys.It used to charge ok ,about 7.2 volts.Over the winter I checked out the voltage regulator and found the points inside were quite worn...So...I bought a NOS Prestolite regulator that is correct for this generator.Start it up ,run at a fast idle with the parking lights on and the voltage slowly,like a few minutes,creeps up to about 7.8 volts.Make a slight adjustment, then restart the engine ( manuals start to restart the engine after every adjustment) the voltage holds at 7.3 ,then slowly creeps up again.So after many attemps I figure the NOS regulator is fucked,buy a new regulator from a Jeep Willys speciality vendor.The regulator says "Made in USA",Great! Not! Doesn't work at all...Take off the cover and I see it's very cheap looking inside compared to the NOS unit.I also see very sloppy soldier job,pack it up for return. Back to the NOS regulator..I've adjusted many Delco units with no problem. This damn Prestolite just won't hold an adjustment. The generator checks out fine,ground out the field wire and it goes to full ouput over 8 volts and the brushes are like new. Anyone have something like this where the voltage won't stay in adjustment?
