You are right. If there was no Ground then the Windings would not pull in the contacts so there would be no click of the contacts. The Cables themselves are in Great Shape because I made my own 1.5 years ago. My son cleaned the Battery connections but tomorrow a.m. we have time to go through the Battery to Relay to Starter connections.
I'll check the Negative Cable to the Block as well.
I guess I was wondering ( since the Starter looked very new when we first got the car 2 years ago) if anyone had an issue where the Relay was clicking in but the contacts within the Relay was still giving a bad connection to the Starter?
