I'm trying to help a friend solve an electrical problem on a John Deere 520 with a Pertronix. He lives in a far away state so communicating is by email and photos. I have zero experience with Pertronix (and friend has no electronics experience) so I'm just guessing that module may be bad based on what has been determined so far. The tractor is positive ground.
My question is (How do you test to determine the status of the Pertronix?) The module is labeled IGNITOR carb E.O. D-57-22. How do you know whether this is version I, II, or III? I noted from Pertronix website that version I is very subject to voltage problems to cause failure.
I suppose a call to Pertronix help is the best way to go unless some of you gurus know precisely what to do.
