Re: (ET) Hot frame (post 2)

[Chris Zach <czach computer org>]

Well, start thinking about it and trace it back. For example:

If the tractor is sitting there with the disconnect off, is there a 
ground fault?

How about with it on?

Now sit on the tractor seat. How about now?

Turn the key, anything?

Take off the brake

Start the motor in forward.

How about reverse?

Walk it through one step at a time and isolate the fault. Then go from 
there.
