John T said: (quoted from post at 17:42:25 11/15/09) That dont sound good because even if you put a genny on the bench n spin it with a motor etc with residual magentism in the iron field poles she ought to put voltage out the ARM post with respect to its frame.
Did you run the Motor Test in the Troubleshooting procedure???? Usually if it passes BOTH those checks it ought to charge. NOTE until the gennys ARM post voltage exceeds that of the battery the VR"s internal cutout relay is open so its not yet even coupled up to the battery so it could charge it.
If you temporarily jump the gennys FLD post to ground does she charge then?? If so but NOT otherwise the VR is bad or the wires bad from FLD on genny to FLD on VR. If she still dont charge when running with the gennys FLD grounded you can by pass jump around the cutout relay n see if she charges then BUTTTTTTTT if the gennys ARM post isnt higher voltage then the battery the relays not gonna close and she still cant charge the battery even if it were BY PASSED JUMPED.
To be safe Id polarize the genny once more then try the ground the FLD test and the motor test but if theres never any voltage at the ARM post shes obviously not working BUT YOU ALREADY KNEW THAT

Thanks John. I did jump the genny's field post to a good clean ground first as the troubleshooting instructions recommended. I had to head out before I got to the motor test so I'll repolarize, jump the genny's field post to ground and run the motor test. I'm on the road this week but will follow those steps in order and let you know what I find as soon as I get back. If nothing else I'm beginning to understand charging systems a little. Shoot, until I got your e-mail I thought the "L" was for lights. Now I think I could wire it blindfolded if I had to.

Today's Featured Article - The Ferguson System Principal An implement cutting through the soil at a certain depth say eight inches requires a certain force or draft to pull it. Obviously that draft will increase if the implement runs deeper than eight inches, and decrease if it runs shallower. Why not use that draft fact to control the depth of work automatically? The draft forces are
