I was wondering if anyone has corrected the situation where the alternator light does not come on when the ignition key is in the "On" position? The other lights that should light are working fine. The tractor is running fine at this point. I have checked the light bulb, fuses and the wiring connections. Thanks

I have a PDF of the tech manual if you want it to look through the wiring and electrical, shoot me an email if you want it

Put a volt meter on the battery while its running to see if it's charging.

Does it have power at the bulb socket? I have seen some bad bulbs before that looked fine.

You should be able to see this on the wiring diagram. Does your machine have an external voltage regulator or is it built in the alt.

I have a pdf of WSM wiring schematic for your model tractor.
The charging light wiring is very simple. One wire from the external regulator to the dash light and another wire from the dash light to a common ground point.
Tried to post picture of WSM page but Tinypic is down.
You could try running a new temporary wire from the regulator to the dash light and another one from the dash light to the battery ground to see if it is not the regulator for certain. If your alternator is wonky, the new regulator would be sending you the same signal as the old regulator so I would be very suspicious of it.
If you want me to send you a pdf of the page send me a private message.
