There wasn't an ammeter. Besides an ammeter is NOT voltage sensitive and a voltmeter is a useless gadget that gives no useful information.

All the accessories and lights ran on 12 volts, some on plus 12 volts, some on -12 volts because the battery center was grounded.

Yah, you need a new alternator or generator when changing from 24 to 12 volts. Its in the kit that Deere will happily supply.

Sometimes the fuel gauge set up for -12 volts reads differently on +12 volts. But it does work. I changed my gas 4020 from positive to negative ground and the fuel gauge still works.
