300 Utility Cigar Lighter wiring

Postby bradm » Sat Jul 06, 2013 4:09 pm

I am putting in a cigar lighter back in my 300U, does anyone know the wiring diagram for it? The tractor still is 6v, positive ground. I think the hot wire goes to the DISCHARGE side of the amp gauge? Do I need to install a ground wire as well?

Any help is appreciated

You would connect the cigarette lighter to the opposite side of the ammeter from the battery, whatever that happens to be.

I think that's the "discharge" side.

Does the socket have a terminal for ground? If so I would run a dedicated wire for ground.

Just as a modern added bit of safety I would also install a 10A fuse in the wire from the ammeter.
