Battery Completly Discharging While Runniong

Postby djohnston47 » Sun Apr 21, 2013 8:45 am

I'm having a problem with the battery discharging while the tractor is in use. I have converted a 1953 super A from 6 to 12 volts. I was thinking that instead of charging, that the alternator is discharging the battery while in use. I don't know if that is even possible. Any and all help would greatly be appreciated.

Thanks

when you replaced the battery with a 12 volt one did you connect it with the - pole grounded? alternators with rare exceptions are negative ground rather than the positive ground on the original 6 volt systems.What kind of alternator did you use? Many of the one wire alternators have to be revved up quite a bit to get them to charge. If you used one of the 10SI or equivalents it needs to be wired like this.

Thank you John,

I used this exact diagram to wire in the 12 volt system. I do believe the new battery is deffective and is now being replaced, so I will hope for the best.

Thanks Again
