Not High Tech BUT............

69 Mustang........ new solenoid, neutral safety switch has backup lights, alternator, ignition switch, wires "look" good, ran fine 2 weeks ago now does NOT crank with key. Jump the solenoid........... no problem. Cannot use meter since I'm by myself for the next few days and arms are not 8 feet long.
Ideas I'm overlooking?
Thinking about just putting spring loaded switch inside to solenoid and saying hell with it. Key on, hold switch, vroom...........

I had a similar problem with my 65 way back when.

Ended up having to replace the ignition switch in the dash.

First thing I changed.

Put a chevy emblem on there it will start up and be twice as fast

Well the beauty of the old Chevys was most everything was interchangeable. Didn't matter

You sure the solenoid has a good ground?

Definitely bolted to inner fender, new one installed yesterday and works fine when jump terminals
Probably wire between there and cabin

 

[Ken King]

Can you get to the ignition switch wiring and run a fresh wire bypassing the wire to the solenoid (not suggesting that you feed it through the fire well yet, just a long run out the door and around to it)?

 

[Kyle]

Only other thing I can think is a fusible link. And Kens idea would bypass that to confirm the disconnect.

I don’t remember the 60s mustangs having a fusible link on that connection.

Put a chevy emblem on there it will blow up and be twice as broke

 

[jrt_ms1995]

Put a Dodge emblem on there it will dissolve in rust and blow away in the wind, thus solving your starting problem permanently.

Another point of view.

Wings, humor me a bit and see if you have continuity from the mounting bolt/s for the solenoid to battery ground.

Have no doubt but will do tomorrow unibody and sits maybe 3 inches from battery and IS grounded, everything else works. It's a wire between solenoid and switch lost in harness or plug.

Probably right, by running a length of wire from the switch to the solenoid you can be sure. After all, if its the original harness you are dealing with 55 year old wiring.
