1010C Electrical

Hello every one. I was out working on my dozer. And the wiring is all chopped up from the previous owner. No idiot lights work, lights were not hooked up the wiring was just all over the place. It is amazing the dozer runs and functions. But today i was working on it more and i noticed in my service manual that it is supposed to be positive ground. And currently my crawler is negative ground. Were all dozers positive ground? Why would some one change it, And would you guys change it back? Also can it do any damage leaving it? By the way my 1010c is a gas with a single battery. Thanks in advanced.

does it charge the battery?....if so don't worry about.....does it have a gen.? or an alternator? if alt it would be neg. ground if gen then it could be either .....look at regulator to see if neg or pos

It has a generator. I will have to put a volt meter on it tommorow to see if it is charging. I have probally used it half a dozen times and the battery hasent went dead. But i started fixing the idiot lights and i got the gen light working but the light stayed on. My other question is i have read that when hooked up in correctly the amp meter will read oppisite is this true for the idiot light.

Also when i check for a charge. If there is none what should i do polorize the generator? Or is something likely damaged?

if it is NOT charging I would pull the regulator and see if it says neg or pos it should ...then go from there ....new reg/ check gen ect.....would not be the first pos ground system hooked up bassacwords if it is

To polarize the generator/regulator take piece of wire and go from the Armature post on the generator to the "non-ground" post on the battery. I say "non-ground" because if you're hooked up negative ground then you would go to the positive post, if hooked up negative ground you'd go to the negative post.
That should be correct, we just did it over the weekend on one of our tractors and it worked, however they're positive ground.

Hi,

The only two things that determine polarity is the way the battery is hooked up and the polarity of the generator has to match the battery.

The meter and regulator do not care, but, the battery and the generator have to be matched up.

If crossed, then the generator will suck the battery down to zero and try to charge it up reversed. This usually results in the destruction of both.....
