Have you verified that you have power to the switch? How are you checking your battery voltage? Gauge of multi meter?

Thanks for reaching out,
I check voltage with my Fluke DMM, No I have been looking for a contact list/wire color ID but I suppose I could just go across the wires one at a time and should show the same 13.2 but if none did whats upstream? I found a factory manual for it but the cost was 300. Think I will do that (check wires for B+ reading Thursday. Need to change coach batteries both are 0.0 but can't see that as the problem should remain isolated until engaging the aux battery circuit.

Power would come from a fuse box somewhere. But I'd poke around that switch and see if you have power in.
Battery will power fuse box
Fuses to ingition
Ignition to starter solenoid
That will be your path
Also,. GROUNDS GROUNDS GROUNDS!!
Good coffee, divorce and elictricity all start with good grounds.

I do not detect any B+ at at the ignition switch connector to the steering column support (aka ground). As for ground yes I tightened the battery ground connection, and getting B+ from + terminal to frame.
Thanks for asking, never hurts to ask the dumb questions,,,,, Like when a car doesn't start and asking how much gas is in the tank.....

Be sure to check the voltage at the cable terminals and not just the battery posts. Corrosion can build up between post and terminal.

You might also try jumping the starter relay. It won't start without power to the switch but if it doesn't turn over you have verified a problem between the battery and all power to the chassis. The starter relay it in the circuit directly from the battery to the starter.
Be sure it is not in gear when jumping the relay.

You might want to check to see if there's a smaller wire from the battery to the ignition switch that has an inline fusible link that may be blown. Just a thought...

Problem is all the fuses I find (3
locations) are good.

Thanks for the electrical diag. can you clue me into the C140 and S205 location wise?? or is S205 the actual ignition switch. Or is S205 the crossover switch in the event chassis battery is dead.

C140 is a 76 pin connector that appears to be inside at the base of the steering column below the fuel pump inertia switch. Pin 4 would be a yellow wire from the underhood fuse box 60A fuse #14 to the ignition switch.
C200 is the connector on the ignition switch.
S205 is a splice that I can't seem to locate in the shop manual but it would be between C140 and C200 which appear to be close to each other inside by the steering column.

Could S205 be that "Brake fluid level switch" why I ask that is, we also have a power steering fluid leak, which due to it being slow being rather then rapid. I suspect it to be a fluid return line or the line going from the reservoir to the pump, and being that it also gives power the the power brakes. We had an incident last Sept. with marginal braking power and at one point at a stop sign everything went dead and then returned, so we could restart and proceed on. I suspect the power lose was due to low fluid level in the reservoir. BUT then on the other hand there is a switch on the master cylinder.

S205 is a splice which is why Ford uses the "Sxxx" designation. "Cxxx" is for a connector number, and "Gxxx" is for a ground point.
So I read the wiring diagram as circuit 37 yellow wire comes from Fuse #14 60 amp fuse out of the engine compartment fuse box, through connector C140 pin 4, and splits into two wires at Splice S205 before the ignition switch, both yellow wires then go into connector C200 of the ignition switch.
The ignition switch contacts can only carry a certain amount of current so they use multiple contacts to split the loads. So the need to have two battery inputs to the switch is required. Ford shop manual describes S205 location as in the main harness near the top of the shift lock actuator located at the left side of lower steering column.
Since there are multiple outputs from the ignition switch, is there anything else not powering up when the key is on such as instrument cluster (idiot lights, gauges, etc), wipers, blower motor, turn signals, etc? Sometimes looking for commonality when something is wrong helps when trying to track down a problem. Is the problem before or after the ignition switch as an example.......
