12 volt system

I used my 9n to jump my truck last weeken when I was out brush hogging. Afterwards the battery on my 9n was dead. It has been converted to 12 volt and there is not much to it but I am not sure where to start. Any help is appreciated. Thanks, Gary

Could be just one of those things and it was time to have a problem or maybe your alternator is bad and just one of those things. I would first charge the battery and make sure it is good and holds a charge for a day or more. Then try it in the tractor and if you have a volt meter make sure your alternator is putting out around 13-14 volts. Then turn off the tractor and pull one of the battery cables off and watch for a spark when you do. If you get a spark then you have something draining the battery and time to track that down

G.S.,
How old is the battery? Check the voltage with no load. If it reads anything less than 12 volts you may have an internally shorted cell. Recheck all terminal connections, you may have loosened them while using cables. Hope this helps!

what type of alt or generator do you have?

Thanks for everyone’s help on this. The 9N has an alternator on it. It was already converted when I got it 5 years ago. The battery is in it’s 3rd year and could be bad. I will start there. I noticed that the amp meter is not hooked up. I am not sure which wires would go to it. Do you have any suggestions? Thanks, Gary

the charge wire from the alt should go to a 2 post ammeter, then to the battery.. usually via the hot solenoid connection.

power for the key and resistor comes off the alt side of the ammeter.. same with lamps.. no other wires on the battery side of the meter. that keeps your net charge / discharge system correct. if meter reads backwards.. swap wires side to side..

It is possible that when the truck started you blew the alternator on the tractor. I jumped my cousins car one time as he had a dead battery. ONce the car started he put the throttle to the floor before I got out of my truck to disconnect the cables and it blew my alternator. I didn't realize it at the time but I went to a ball game that night and I noticed that my lights were dimmer and the turn signals were working real slow. Next morning, I tried to start the truck and the battery was dead.

I think you may be right. Or at least it was time for it to go because I took it off and had O'Reileys test it. Yep it was bad and I got ane (rebuilt)alternater for 47.00. I got a bunch of funny readings from my volt meter on the new one and I may need to change the way they the one wire system is set up. So far it is working. Thanks for everyones help on this.
