Gents...thanks for all the replys...
I do have the electric jacks stowed, and slides and steps in. I have started the motorhome before with jacks down and slides out, so I don't believe there are ignition interlocks there.
I have replaced that on frame starter solenoid between the steering column mounted ignition switch and the starter. It is located in the passenger side wheel well. The primary wire was loose on the small post, so I tightened it up, and also cleaned up the two large post wires.
I have not replaced the key switch yet, but that might be my next item. Of course there is still high probability it is a ground somewhere in the ignition circuit. I'm still trying to find a usuable ignition wiring diagram without having to buy a $250 2004 F53 shop manual.
So, with this, you're saying that there is no voltage on the aux. solenoid coil pos term and assume you're in command of a voltmeter?
That being the case, is there voltage on the ignition sw. term.?
If so, running a new wire from the sw. to the solenoid should do the trick. Try a temporary run for just touching it with 12v for beginners. If that doesn't get it, then possibly the sw. itself isn't making contact, when the key lock is turned.
My old P30 chassis coach, had a steel rod down the side of the steering column, between the key lock and the ign. sw. that required some adjustment.
Thanks for the reply. Yes, I have some voltmeter skills, but the son is a ninja (using that electronics/computer repair and programming education I paid for). He has checked the starter solenoid both at ignition on and at ignition start and I think he said the 12v on the primary wire (small lug) is not there at start to close the solenoid for the starter to get power.
Some background...up until last Nov, the MH stayed plugged into 50amp at home, but I would occasionally have to "wiggle" the gear shift to get the MH to start. Last Nov, we moved and now the MH sits in a storage lot on the Navy base with no power and batteries on disconnect.
Dec it wouldn't start, so I got a new AGM battery (has already been told before I moved that chassis battery was not well). Even with new battery I still had starting issues...having to wiggle the gear shift, and that is why I replaced the trans park/neutral switch. I usually could get the MH started after fiddling with it for a minute or two. Later, I could start the generator and get the (new) chassis battery up to 13.4v, and the MH would usually start.
Trip to ARK in Jul, ended up replacing the ignition switch that is mounted to the steering column. My BIL is an after market installer, and he determined that ignition switch was bad. MH started for the trip home both times I needed it to. I parked the MH in storage on 8 Jul and disconnected the batteries. Went to go start it a couple weeks later and nothing.
So I am still easter egging it, using my Son and a neighbor with auto repair skills to find the problem, replacing the starter and starter solenoid to no avail. I think it is probably a loose ground or wire. I have a set of jumper leads so next week-end when the Son is available, I'll work on running a direct wire from the ignition switch to the starter solenoid.
I can get the MH to run by crossing the starter post with the ignition to on, so I might just get it running and take it somewhere and have someone with experience look at it...cause I'm sure it won't start for them to get into a bay, and they'll have to figure it out in the parking lot.
