Thanks for the additional diagrams. I still have not been able to determine why wire #16 remains hot. The switch works fine.....unless the new one I installed was bad as well. I also performed this step,
Part 1 -Ford EEC Power Relay Test.
to determine if the eec power relay was good and it checked out fine.
I have a couple trouble shooting questions.
First, the #16 wire has power at the switch even if the switch is off. Wire #16 should only be powered when I move the switch to on/start/eccessory correct? The black clip that holds the wires that clips into the switch has a lot of grease and gunk on it. How do I check to determine if it is shorted in this clip? Possibly getting power off wire #37 (Battery wire)?
Second, when I hook up the battery I hear clicking of components that are powering up. The dash (check engine etc...) remain on even with the key in the off position. Also, when the motor is running the windshield wipers will work. When I turn the switch off, the wipers quit working but the coach remains running. This tells me the on/off of the ignition switch is working?????
Also, how is the house battery and generator tied into this circuit? I keep going back to my friend trying to jump the generator with cables to his pickup while my motor home was running. The alternator charges both batteries and should have a isolator???? to the generator when it is operating in place of the alternator. Is there possibly something that is keeping the circuit closed?
If there is a short I am leaning towards it being in the clip that connects to the switch but can't figure out how to check it. This is really frustrating and I truely appreciate all your help.
