    Default Farmall A battery question

    When I was taking the 6-volt battery out of my Farmall A to replace it I noticed that the positive terminal was grounded to the fame and the negative went to the starter. Is this right, or does it matter? [img]/forums/images/graemlins/confused.gif[/img]

    Yes it does matter. If it was working correctly before, keep it a Positive ground system.

    All Farmall 6 Volt tractors have a positive ground.

    Most antique tractors that were 6v were positive ground. Mainly due to the edison effect and the spark plugs.

    I was told that positive ground systems had "increased corrosion problems" and that this was one of the reasons for the switch to negative ground... make any sense?

    My understanding is that positive ground had decreased problems...

    I have always wondered why the move from positive ground to negative ground happened. Not wanting to hijack the thread and this is a non issue with CUT's, but since we are in the Vintage forum.....
