Checked Affordable and they didn’t have one. So I ordered a voltage regulator from Discount tractor in TX, it was not the same box size,way smaller in fact,but the contact prongs measured the same. Cost $43 shipped, put it in and everything works fine now. You can’t go on any numbers,so you pretty much have to measure and compare the parts.

Thanks

Okay,cleaned all connections,including those to/at fuse panel, still no output from alt.
Checked again and still have L-R
red wire 12.7 bat voltage at all times, assume this is charging wire to batt
grey/white wire 0 volts off/on/or running
black wire 0 volts, assume ground wire
Brown wire .14v off,.33v on,.43v running assume a signal wire

The Foton opns/maint book electrical diagram is absolutely terrible but i think it shows
Red- batt
Grey/white has an F by it,Field wire is my guess,shows going to regulator?where?
Black =grnd
Brown also shows going to a regulator, but I do not see an external regulator box anywhere.

So if G/W is the field wire, it would need 12v to activate alt,is there a fuse for it? or where does it connect to get 12v to alt?
I’m tempted to run a fused 12v hot wire to the G/W alt terminal from batt, to see if that excites the field? If that works I could tap a new wire to the run wire off ign.

I tested ignition switch and a Blk/Wht wire is always hot, in acc one red wire is hot,in run 2 red wires are hot with 2 more wire left i assume one is hot in start,not sure on other. Is one of these to field or does it come from another location to Grey/Wht wire?
