WD45 Electrical Problem

I had the lights on my WD45 on for quite a while the other night. The meter showed discharge all the while. The next day even though lights were off the meter showed the same discharge rate. When I shut off I could not restart the tractor. Tractor has always had a slight charge during day with lights off. Any idea what the problem could be? Thanks for any help.

Mark, your question is pretty wide open so I will just post my Troubleshooting Procedure (no use in re inventing the wheel every time this question gets asked) and if you work through it you should be able to diagnose the cause of non charging, perhaps the genny needs attention like worn brushes or perhaps the battery itself is at fault. Para 5 gives a procedure to determine if non charging is a Genny versus a Voltage Regulator or Cutout Relay and light switch type of problem.

See if while shes running she will charge if you temporarily dead ground the gennys FLD post to ground????? If so but NOT otherwise the genny is okay so the problems in the Voltage Regulator (if thats what you have) or in the light switch control charging circuit/system (if thats what you have)

With the lack of info you give it is impossible for us to help you much if any. 6 or 12 volts??
Genny or alternator?? Now that said it could be a weak genny, a VR not set right or not working right etc etc.

Sorry for lack of information. I have a 6 volt system with a generator.
