If the VR's internal cutout relay is failing to ever close and by pass jumping across it (BAT to GEN/ARM) makes her charge yeppers sounds like a bad VR HOWEVER that assumes shes all wired right and all polarities are correct (genny and ammeter and battery etc). While what you say (that pegged ammeter dont sound exactly right) and my test tends to say that Im still concerned all your polarities are correct because the more common VR cutout relay problem is them sticking closed versus failing to make up.

If the ammeter polarity (and battery) is correct, if you turn on lights or ign engine not running it ought to swing over to - discharge!!!!

Id say the jury is still out

 Re: Generator Polarize in reply to John T, 01-30-2013 15:30:51  
I wired up the entire tractor using the wiring diagram I found on this site. And when I turn on the lights the ammeter does go to the side of the meter marked "Discharge". And it is wired positive ground as the diagram shows. So when I did go through Step 6 in the repair instructions and the ammeter needle pegged on the charge side after jumping around the voltage regulator, I figured the voltage regulator probably had got fried when some of the wire insulation was chewed off by the mice in the barn and shorted together. I probably should have put a voltmeter across the output of the generator to see what it was doing at the time. But I didn't think of it in my haste to go buy a new voltage regulator and get home in time to cook supper.
