Thanks!

When it is connected normally to tractor there is an easy test to check weather your gen/starter is bad or of the VR is bad. I am assuming your battery is not charging.

If you provide ground to the F terminal on the SG and it puts out charge to battery the VR is likely bad. Do not ground this longer than a a few seconds. Have a volt meter attached to the battery while doing this to see the voltage increase or look at you charge meter on dash board. You will hear a load on the engine also if the SG starts charging


Before doing this check to see if wiring looks good. Clean and tight connections. etc.
