Project car: assuming bad starter relay. Confirm?

Demonic... you totally got me on track. I found that I couldn’t get a ground from the relay housing... or anywhere on the fender... which made me think the fender isn’t grounded? Which led me to remembering that I had a ground connection dangling from the firewall in the engine compartment... then I remembered a line from an electrical post I read a few days ago.. “remember to ground the firewall strap to the motor” once I got that connected, the relay worked perfectly on key “start” position... lit up my test light, and made the faint “clicking” sound. :lol:

Thanks for the responses guys... I know electrical problems are super difficult to troubleshoot from afar, and often with missing bits of information!
