My name is Bob in IL. I just purchased a 90s modle Mahindra 485DI with a loader. Very nice little tractor , with very strong engine and clutch! My question today is the wiring on it is a bit rough! All the lights and turnsignals are broken/gone! Not really concerened about that , my problem is the charging system! I spoke with Dan in Texas ,i belive, service manger there , he says the yellow/green tracer wire at the alt. should have 12 volt with key on, I have no voltage. I had alt. checked at NAPA, and it put out 10 volt, so I ordered a new alt, but i was hoping to find a wiring diagram on the 485 , so I can by pass / remove all the lights and etc, and get the yellow /green wire to put out 12 volt!! Any thoughts would be great!!! Thanks! Raining here!!! too much!!
