Starter running on when started??
Hi I'm new hear and hopefully this is the right forum for this, Heres my problem I did a cab swap, I put a 1979 Ford F150 (4x2 400 ci engine auto)cab on a 1974 Ford F100 shortbox (4x2 289 4spd) everything went well till I tryed to start it. Started fine but when I back the key to run mode the starter stayed ingaged what is up with that??The only way I could get this to stay started without running out and disconnecting the brown wire from the starter relay?? So what my friend did was swapped the orange and brown wire from the starter relay and spliced into the brown wire to put in a pushbutton switch (in cab) to start the truck every time?? Works but I want to make it a turn key!
Thanks In advance 74 Forder.

Did it start cranking before you turned the key to the start position?
I'm going off of memory, but I believe there should be a Red/ Blue wire to the S terminal at the solenoid. The Brown wire should go to the I terminal. I can't remember on the pickups, but on the Broncos, the orange wire is the Field wire from the alternator to the Regulator.

I'm thinking you should be able to swap the Red/Blue and the Brown on the solenoid and be good to go.
Your welcome,

Did I post something useful, if so click the scales and say something positive. (stolen from MBeavis)

Sorry RCrawler it was that way when he first started the wires were red/blue on the S terminal and the brown was on the I terminal (when you say solinoid you mean starter relay?)thats the way it was when the starter was engaging ?? So he swapped them around and spliced into the brown which now is on the S terminal for the push button switch in the cab?? If that makes sence?? Thanks

You're starter relay is the most likely problem. They don't have to stick on at every start. Just from lack of use mine does it every now and then,I have to diconnect the battery to stop starter, hook it back up and it may not do it again for weeks. There only about 15-or 20 bucks so cheap fix.

Do you have a constant 12V or a ground at the Red/Blue wire?

The brown wire supplies 12V to the ignition for easier starting. With the engine running, you should see 6-8V there from the resistor wire to the coil.
Are you using the wiring harness and ignition from the 79?

Thanks guys for all the help. Yes NOCO77 i did use the ignition from the 79. RCrawler I'm not sure if there is 6-8v from the resistor to the coil? I'll have to check later when wifey comes home..Dusty all your saying is to take off the red wire and leave it off and hook a ground wire to the I pin of the starter relay?? Thanks huys

Check the red/blue wire. Should have 12V only in crank position. If you release the key from the crank position and you still have 12v, I would suspect the ign switch or a wiring/ switch issue if you mixed and matched.
