Need to work with 6 volts more often

Put a new 6 volt battery in my Allis Chalmers C today. Was hard to start and when it did it ran rough. I noticed the amp meter showing discharge and knew what I did. Unhooked the battery and reinstalled it as positive ground instead of negative. Work with 12 volts too much.
 
A model C should start pretty decent on six volts. You need to clean the rust out of the connections. Where the ground strap bolts to the battery box needs to be clean. Where the box bolts to the torque tube needs to be clean. And where the starter bolts up needs to be clean.
 
Your problem is you do not stop to think before you do. Now days it is sad to say many people do not think before they do something then wonder why they have a problem. Not jumping on you just saying it like it is
 
Though in my accumulation of a dozen or more battery equipped vehicles, all 6V are positive ground and all 12V are negative ground, I'm sure there are also negative ground 6V and positive ground 12V systems out there.
 
Many English cars where + ground back in the 50s and 60s and 12 volts. I learned that the hard way when I hooked one up - ground and fried the alternator.
 
I bought new heavy duty battery cables for my old tractor, it's a 12 volt system.

I think the cable were size I or 00.

Odd they both had black color wire covers, however each cable came with an id strap to install onto each cable.
One red "+" and one "-".

Works fine, but I was used to the + cable being red.
 
i'm surprised it ran rough..

shoulda ran like normal.

the genny even repolarized and was charging ( meter reading backwards is no biggie.. )
