This agrees a lot with my friend professor Jim (janicholson) but heres my inpit FWIW

1) If the genny tested good its likely okay

2) The new VR is likely okay

3) THERES A GOOD CHANCE IF THE GENNY WAS TESTED IT MAY NOW BE POLARIZED AT NEG GROUND SO I WOULD RE POLARIZE IT AT YOUR TRACTORS GROUND JUST IN CASE ITS OPPOSITE (see how to in my procedure)

4) Make surt the VR has a good ground, or even run a jumper wire from the batterys grounded post direct to the VR metal

5) Also make sure the genny has a good ground???

6) POlarize the genny (before starting),,,,,insure VR and genny grounds,,,,,,,,,put voltmeter on battery and read voltage (6.3 if 6 volt 12.6 if 12 volt),,,,,,,,,,,start her up and at fast RPM the battery voltage should increase if shes charging to 6.5 to 7 on a 6 volt or 13 to 14 on a 12 volt DOES IT?????????????? If so shes charging regardless if ammeter works or not.

7) If no charge temporarily jump the gennys FLD post to ground see if it charges then?? If so but NOT otherwise the VR is bad or not grounded or teh wires bad from FLD on VR to gennys FLD post

MAKE SURE ALL IS WIRED CORRECT?????? It may not be wired right

If its wired right??????????? Polarized right???????VR and genny well grounded????????? run my Troubleshooting procedure below

I may be down a WHILE Im replacing my hard drive today or tomorrow

Today's Featured Article - Product Review: Lead Substitutes - by Mike Schordine. Lead was oriinally added to gasoline as an upper cylinder lubricant. It lubes the valves and seats. If you rebuild the motor, you could use hardened seats and valves, and unleaded fuel. But if your old tractor runs good, a simple lead substitute added to the gas is a perfectly reasonable solution. And, if you are like me, your tractor is under cover, but it sits outside. So with every temperature change, the humidity in the air collects in the fuel tank, in the form of water. ...
