I have a 1970 F250 W/360, auto trans, origional. When I turn the switch key to start, the red light beside the switch comes on, but the starter does not engage. I have a fully charged battery, I can start the it by grounding starter "cylinoid" to positive battery post with switch in the "on" position and it will start and run. I have replaced the "cylinoid" and have the same problem. Can anyone recommend a repair, or identify the problem. I know there is one nut loose behind the steering wheel.
I do appreciate someone correcting my spelling...I take no offense to it...I was born and raised in Georgia...48th in education out of 50 in national averages. My spelling is horrible...and I know it...thats why I put the word solenoid in " " because I knew it was misspelled. This message board does not have spell check.
I was taught by my grandaddy to take a long screwdriver and touch it to the first small post and then to the Positive battery post to start older cars and trucks. I have no idea what an "S" post is on the solenoid. Thanks for all the input. I probably have a broken wire somewhere... :-X11
that trick works great. the small terminal that you are touching is the S terminal. this gets power from the ignition switch, and energizes the starter.
I thought about the transmission slector switch... would that not prevent it from being jump started as I said I can do, if it was bad?
Can you advise exactly where it is located? I did have a load on it when it started acting up. I thought maybe that may have indirectly caused stress on the switch and caused my problem.
Hi, the switch at least on a 72 is on the steering column before the firewall. To adjust, loosen the two switch attaching screws. Hold the gear selector lever against the neutral stop.
Move the sliding block on the switch to the neutral position. From the rear of the switch, insert a #43 drill in the pin hole. Slide the switch to permit the switch actuating lever to contact the switch sliding block (this is as clear as mud).
Tighten the two screws and remove the drill. Check for starting in only neutral and park.
By using the screwdriver from bat+ to the start terminal on the solinoid, you are just by-passing the ign switch and the wiring that goes to the S terminal. If the above procedure fails, check for a bad switch by shorting out the wires on the switch.
