Spent the day at the Millville NJ race track today 85 degree weather. Went to start the car at 5pm and nothing happened. Battery is good, turn the key and nothing, no clicking or anything. Gauges work, gas gauge etc. The guys gave me a push start and it started, drove home for 45 minutes with no problem. Pulled into the garage, shut it off, turned the key and it started! I have the Ford 6 volt starter solenoid installed between the starter and the ignition switch. So where do I start? Being it started, I can't trust the car starting if I stop somewhere and shut it off. WTF?

As I continue to preach, the hot start relay is simply a band aid that masks other problems . . . Until it doesn’t.
Start with Clays suggestion - verify you have 12v on yellow solenoid circuit from the ignition. Then you need to measure voltage drop with at DMM across the ground strap while cranking. Anything more than about a 50 milli-volt reading is too high. Do the same thing for all your battery cables. Read this link before you go throwing parts at it. https://www.fenderbender.com/running-a-shop...ircuits-part-11 |
