Is it 43.3 ohms or is it 43.3 k ohms? Also using diode check mode on your meter do you get anything from B+ to the case ground.

43.3k ohms. B+ to case shows 43.3K and one of the AC lugs also shows 43.3k both to case ground. Between the two lugs that shows the 43.3 it reads 0.00k.

Then is a fairly normal reading using regular resistance check. Those two terminals are probably center and the RH one with terminal facing you. Do diode check between any of the three terminals and the case, they should be register "OL" Both forward and reverse.

Or at least the two regulators here checks this way and they are new, never installed yet.

With the terminals facing me it is the left and center.
I did a diode check and you are correct, I get a 1 (all three of my meters use 1 instead of OL) both forward and reverse.
Don't know if it matters but with the + lead on B+ and the AC to the left, I get a reading of .021, reversing the wires I get .033.

I'm just at a loss as to why if everything is hooked up, it will blow the fuse as soon as it is put in the holder but with the rectifier unplugged it will not blow the fuse and will start and run.
Maybe I missed a short in the purple wire, key switch or something. I'll check again in the morning.

If it works without the regulator connected, but blows the fuse as soon as it is connected I would say the regulator is shorted, and needs to be replaced.

Thanks guys. Replaced the rectifier/regulator and it lives. Checked the volatge at WOT @ battery and it showed about 14.5 +/- volts.

It appears now there is a much bigger issue but not with the regulator or charging system. Seeming unrelated but who knows.
