Wiring diagram

Postby Bamacub » Sat Jan 09, 2021 3:06 pm

All diagrams show battery wire from voltage regulator to charge indicator on the minus side, if I wire it this way it shows discharge. If I change the wires on the amp meter it shows charge.

Is your tractor system pos or neg ground? Looking through your previous posts I cannot determine what year/model you are referring to. TKS

All 6volt Cubs are Positive ground tractors.

Agreed if original (I've seen some weird systems in the past). You never can tell what someone might have done to it. :surrender:

Is the 12 volt generator/regulator something you installed?

Polarized the regulator?

If the 12 volt negative ground installation was done on 6 volt positive ground system, then you need to change the wiring on the amp meter as you indicated.
I have an excuse. CRS.

It's a late model 12 volt original cub. I am building a wiring harness, it was a big mess when I got it. A non runner I am bringing back to life.

Welcome to the forum. Sounds like your Cub has several electrical modifications to the original factory setup (12v Battery and alternator on a 49 Cub). Do you have a two prong push-pull ignition switch?

Start a new topic. You have a different problem than the original poster.

The problem is that the alternator is back feeding the ignition system when you push/off the ignition switch.

We will need more information to solve the problem.

I agree with Eugene, you should start a new thread. The solution is an easy one but we need to know what equipment you're running.

Thanks... being new to the forum I didn’t know how to start posting. Will start a new post and seek help that way. Looking forward to being a part of group with so much knowledge on Farmalls.
