3010 Generator

[sfcsanderson]

So my Gen light has been on since I rebuilt the top half of the engine. I took the generator in and had it tested and cleaned up. It bench tested good at two different shops. Slapped it back together and the Gen light is still on. It is a positive ground system. I tried to polarize the generator by jumping the battery terminal on the regulator to the field terminal for the generator. This didn't work so I jumped straight from the battery to the field terminal on the generator. My light is still on. Does anyone have any suggestions?

Thanks

YES I have some suggestions:

You can Polarize by jumping from the BAT terminal on the VR over to THE ARM/GEN TERMINAL NOTTTTTTT THE FIELD (F)TERMINAL. Or from BAT direct down to the gennys ARM post

Sometimes genny shops will Polarize the genny at Neg ground ya know, so Id Polarize it on the tractor BEFORE STARTING

If the genny is at the wrong polarity you can harm the VR so be careful

Try to correctly Polrize the genny then start it n see what happens

The VR needs a good ground to work ya know, make sure BOTH the Genny and VR have good grounds

After you polarize n start her (with good genny and VR grounds) if still no charge, when shes running, momentraily jump the Gennys FLD to ground n see if she charges then??? If so then but NOT otherwise, the VR is bad ot not grounded or the wires bad from FLD on Genny to (F) FLD on the VR, or other possbile problems.

If all that fails, rum my Troubleshooting procedure below to diagnose the cause of non charging. Sure the idiot light is wired correct??

This is a gas or LP, 12Volt tractor , and not a 24V diesel??

If so, the generator should have an "A" field circuit, where the regulator grounds the generator "F" terminal.

You may have burned out your regulator by applying battery voltage to the F regulator terminal, as this will cause a dead short through the regulators field relay and resistors, causing them to burn out.
Try using a jumper wire to ground the generators F terminal to a clean shiny spot on the generator case.
This will bypass the regulators voltage control circuit and make the generator charge full output.
Do not allow the generator to operate very long with the regulator bypassed, as it will heat up fairly quickly. If jumpering the generator F terminal to ground makes it charge, then your regulator is defective or poorly grounded.
