any difference for a positive or negative ground front mount distributer on 8n

[trapboy]

do I need a positive ground distributor for the 8n or just wire the tractor that way, correct ?

Just wire as negative ground, Correct. If you have a generator you will likely need to polarize it to negative ground.

Jim.ME means to polarize the generator. The distributor doesn't care.

Hi trapboy, are you using your 6 volt positive ground EI, or going to points?

If pertronix 1247ap6, it must be positive ground, or it will fry.

 

[Jim.ME]

Yes, I meant polarize the generator.

To reinforce soaked's post; If you have a positive ground 6-volt EI, you left out some very key information when you asked your question. A points ignition would not care about the ground. You cannot just swap an EI unit between positive or negative ground; the unit must be the correct ground for the tractor. If have a positive ground EI now and you want to go to negative ground; you need to purchase and install a negative ground unit.

No I am going back to points

Here is a diagram for 6 volt positive ground, like it was from the factory.

Happy to help
Did your EI end up failing the bench test?
