6v / 12v question

My tractor has a generator, which the previos owner thinks is a 6v. However, it was running on a 12v battery when it last ran, and it has a voltage regulator (square in the back of the block) Could a tractor have a mix of 6v / 12v?

He is throwing in a new 6v battery he never used, so I am going to make the system 6v. But how do I check the generator? Could this be a cause of the tractor not running?

Mike, You better start shopping for a new grill too. I have several. That one looks like about 30 dollars in materials and 20 hours or so work to be presentable.

Mike, IFFFFF youre gonna make it 6 volt now regardless, the old genny may work or can be made to work at 6 volts regardless if its really a 6 or a 12 PROVIDED you use a proper 6 volt Voltage Regulator. A genny dont necessarily know what its voltage is supposed to be, it increases as its turned faster and/or more amps are pumped through its field windings which is the Voltage Regulators job/control. A 6 can still charge at 12 if a 12 volt VR is used (although not all that great and its NOT engineering correct) and its also possible for a 12 to charge at 6 if the old genny happens to be a 12 and youre gonna convert over to 6 n use a correct 6 volt VR.

Id get a known good 6 volt VR or use yours if its really????? a 6 volt,,,,,polarize the genny,,,,, see what happens.

If it its a Magneto Ignition you have no coil or ballast problems to worry with, while if its a battery powered coil ignition then the coil voltage n ballast has to be addressed.

A working or non working genny wouldnt be the cause of it not running if its a magneto ignition as far as spark n ignition are concerned, but could be obviously if its a batery start n she wont crank over DUH

Let us know

I see yours has a mag. It will run with or without an electrical system. As for what type 6/12 V. It may be stamped on the generator case. Also check the back of the regulator - it too may be stamped with a voltage.
