I've known of this problem. I had a 79 bus that has this relay setup. I'm just in disbelief (reason unknown) but it sure is sounding like the likely cause. I guess I just didn't want to believe it could be this and was sure it was a "hard" part failure. So much for gut instinct. For the record, I did in fact, clean a bunch of grounds off back in the engine bay and the tranny area. Unbelievably, they were clean. Weird, especially for coastal Florida. OH, I made a typo on the original post. I meant to say "Ignition switch" and not "Starter" switch. Thanks to Jake de Villiers for pointing that out to me. No need to confuse anyone more than I already have. I heard the old standard Ford relay is the relay of choice for this due to it's simplicity and low price.
