Re: 1972 does not turn over when hot
That's a nice little shield. I had a gear reduction starter on mine and after ten years it gave up the pooch and started giving me issues. I replaced it with a stock unit because I needed one right away and could not wait for shipping. Turned out that the starter drive was bad on the unit I replaced. For what it's worth my solenoids work perfect now and the truck starts nice even in the hottest of conditions here in Florida. Those dual batteries are very nice too though.

Re: 1972 does not turn over when hot
Funny. The OP found a bad ground around post #15, yet people continue to babble about adding another solenoid. Fix the wiring!
Guess what--the original solenoid is still there doing what it always has. By adding the new solenoid and redoing the wiring, the problem is solved. Sadly the redo of wiring is the fix, not the new solenoid. Next time, you have 2 solenoids to troubleshoot. Not to mention snickers if you go to car shows. |

Re: 1972 does not turn over when hot
Funny how your post has no helpful information at all and you say the rest of us are babbling which is also unhelpful.
Guess what-Some of the information here is helpful and if solenoids don't help then why are so many of us benefiting from using them. Maybe for a stock situation they are not necessary but hundreds of us have highly modified rides. Many threads start with a problem and OP fixes it but the thread goes on to help anyone who reads it and has that problem. Every post brings it up to the top of the list and it has the potential to help. So negative comments are not helpful-there I go babbling. I'm out.

Re: 1972 does not turn over when hot
Like I said, fixing the wiring is the solution, not adding another solenoid.
Measure the voltage to ground at the S terminal of the solenoid. It will be low causing the solenoid to not work. Trace the purple wire back and fix the issue. The ford solenoid switches the starter cable as well, for no particular reason on a Delco starter. I bought a truck that had 2 horn switches, 2 ignition switches and a ton of 12AWG red wire because it seems the PO also didn't want to spend time solving the actual problems. Same concept w/ ford or other extra solenoids. |
