Just looked at my Robert Bently Manual...

Regarding my question if the paint needs to be removed below the solenoid so it contacts bare metal...

What do you make of this?

Just run a ground wire as shown in this mod of your picture. Use about a 10ga wire with a ring at each end. It would connect under the mount bolt head and the bolt on the battery brace where the main body ground attaches. That is where it gets its ground to operate the solenoid. You could clean under it but it will get corroded again.

UPDATE:

- I added a 10 ga Ground Wire as Dan suggested.
- Still not working
- Tested battery = 12v
- tested hot side when key turned = 12v
- negative side when key turned = 12v
- Ran a jumper from battery to hot side - didn't work...then suddenly worked for a second...then I could never duplicate that.

Solenoid bad? (Even though new)

See pic of the Black Ground wire I added.

Probably a bad solenoid, I put one on and it was bad right out of the box.



'S all for now

A fiend of my wife visited some time back, when she came to leave she was sitting in her car several minutes. I went over to see what the problem was.

She had about 15 keys set out on the drivers seat and was trying one after another.
She explained that the car sometimes 'prefered' a certain key!

The following weekend I fitted a new starter solenoid to her car and there was never any further problem.

Get another solenoid.

mine is grounded by a star washer under the base that bites into the metal.
the coil's internal wire (has a wavy washer connected to the coil's fine wire, may not be making full contact) could be broken wire inside, have to take it apart to see that.

I agree, bad solenoid.

Ordering a new solenoid!

Go to your local FLAPS and get a Ford solenoid. 10 bucks. Built to handle the current necessary for the big V8s. Not stock, but works very well.

Agree, most people would not know it was not the OE item. I see many owners on this site using them.

Out of curiosity, is it this one?

https://www.autozone.com/batteries-starting-and-charging/solenoid-switch/duralast-solenoid-switch/118604_553059_0?fromString=search&make=Ford&model=&year=

So this would be mounted in a different place? Like Doug in Vegas did on the wall?

Plus I would need some kind of spades to connect current wires?

Re use the spades from your old one. Mount it where you like.
