6 volt generator problem?

I don't know if the generator on my super m is charging or not. But, with the engine off and the lights turned on, the amp meter goes to the charge side instead of the negative side. Would like to fix that first and then check out the generator. I have the battery positive grounded as the manual says. Thanks for any suggestions!!

Gordy - You need to swap the wires on the ammeter terminals in order to make it read correctly. (For safety temporarily disconnect the grounded battery cable while swapping the wires!)

A battery installed backwards will cause reverse ammeter readings, too. Pointing out the obvious to most, but......

Gordy, hmmmmmm say the tractor battery got installed OPPOSITE from the correct polarity (likely at 6 volts was Positive ground originally) that would make the ammeter register bass ackwards as you indicate......

Buttttttttttt if the genny were correctly re polarized it could still be charging fine, its only that the ammeter would then show discharge when shes running at fast RPM

Sooooooooo what does the ammeter do when shes running is the obvious question???? Cuz if it swings to - discharge and more so as RPM increases, she may be charging !!!!!!!

Put a voltmeter on the battery and just sitting there NOT running Id expect around 6.3 volts but then when running at fast RPM ifffffffff the battery voltage rises to the 6.5 to 7 or so range SHES CHARGING AND YOU SIMPLY NEED TO REVERSE THE AMMETER LEADS to make it register correctly. HOWEVER you may wanna take it back to the original Positive ground,,,,,,,,,,Polarize the genny BEFORE you start it up,,,,,,,,leave the ammeter as is and it should now register correct.

Whatever you do POLARIZE the genny (see instructions in my procedure below)

Geez, Thanks for the information guys. I've printed everything off and will work on the tractor tonite. Hope I get the thing to work soon.
