I've heard about this problem before. You've been driving on a warm day and, at some inconvenient stop, the starter won't engage. Dead. Nothing. Nada. Battery is fine but no action from the solenoid. Bump start works and you get back to your home just fine. Next day the car starts as if nothing was wrong. People with more knowledge than I, and they are legion, tell me that this is a common problem with the teener. Thanks for that but I would like to know what the root cause problem is. My car has been run on hotter days for longer periods and this is the first time I've experienced this failure. Is it a wiring problem, a weak fuse, a tired old original part or what? Inquiring minds want to know. Thanks.

Typically if your ignition switch is OK. Its dirty grounds or a dying starter. the tranny strap design with its open webbing eventually looses its ability to transfer electrical current efficiently. Get a new tranny ground strap and clean the body and tranny where it attaches. Get a new ground cable for the battery and clean where it connects. The car is 40 years old, some starters are 40 years old Some battery cables are 40 years old. Most tranny straps are 40 years old. Ford had an issue, probably still does where whatever they used for cables, or whatever was going on (seen some threads on this, but forget) the battery cables would rot from the inside out...in several years, not even a decade. The greenies you would find when you open up the cables was the issue...just made it harder to move electricity through the cables. A relay will mask an issue and allow you to ignore it. Might not fix the issue at the end of the day. |
