|Tim Browne||Does (or should) the Oliver 1800 have a positive or negative ground. An individual working on mine this weekend seems to think someone changed it from positive to negative somewhere along the way? Thanks in advance for any replies to this inquiry.

|Ron||Which model... A, B, or C?
|Tim Browne||It is a model A
Thanks in advance for your reply!
|Ron||Positive ground from the factory. Many people who don't know any better attempt to change them to negative ground and do a poor job at it. Both the Operator's Manual and Service Manuals have wiring schematics in case you need to rewire your tractor.
