Verifying reversed polarity

Posted by LRRifleman on May 27, 2012 at 15:12:56 from (108.117.4.46):

Hello!

I have a 1958 International 340 Utility that was converted to 12 volt by a previous owner. After having the engine checked due to starting difficulty. I was told that both the starter and the voltage regulator were "fried". Fortunately, my local (agricultural) Case dealer can get the parts I need at a reasonable price. However, being on pension and disability, I want to do the work I am capable of by myself, so I can avoid the estimated $500 labor expense to replace the starter and voltage regulator!

When I spoke with the people in parts, I was told when the conversion was done (if it was done properly), the starter should have been rewound for a 12 volt system, and the ground polarity reversed, from a negative ground to a positive ground.

What should I look for on my tractor to confirm that the ground was switched from a negative ground to a positive ground? Is it as simple as tracing the positive lead from the battery to the ground point on the chasis?

Any and all constructive advice would be vastly appreciated!

Thanks, Ed
