Short Circuit During Key Accessory Position

jwelch68Member

Good Evening,

I'm having an intermittent high current draw/short circuit when the key is in the accessory position. Sometimes I can go switch from Accessory to Run and it will start and other times it won't. I thought the starter may have been hung up again and maybe the starter was pulling lots of current. I was able to remove the starter one time and ground it with battery cables and everything work fine. Started the car a couple of times with no issue. Came out the next morning and the problem returned. I was able to duplicate the short circuit with the starter removed so I think I've eliminated the start has a problem.

The key switch schematic doesn't really have a path to ground so I don't believe that is the issue but I guess there is a chance.

I'm an electrical engineer and have a DMM and current probe so I should be able to figure this out, fingers crossed. Just curious if anyone has had similar issues or any idea where to start?

Thanks,
John
