false ignition key on signal

[stvhans69]

First time out in our new 2017 Baystar (3401). First night we leveled the coach, then went to put the bedroom and wall slides out. Nothing. My wife also noted that the door steps would not stay out when the door shut regardless of the position of the step switch, also the backup camera would not turn off.... all this even though the ignition was off and the key was out. After many hours on the phone with Newmar (their technicians are the best) and the Ford people it was determined that the problem was in the fuses and components installed by Newmar. What we could not determine was why the slides, backup camera, and steps were getting a false reading that the ignition was on. Spent a sleepless night with the slides in then headed to our next destination. When we pulled in and turned off the coach everything miraculously worked.... the slides went out, the steps would stay our and the backup camera turned off. this time I did not level until after the slides were out because I noticed that the level system did recognize correctly whether the ignition switch was on or off. The local RV repair guy said that he had heard that the wire under the drivers side going into the fuse box which determines whether the ignition switch is on or off sometimes picks up nearby stray electrical impulses (like from a radio, which was not on) and sends a false signal to the components that the switch is on..... don't know whether I believe it or not but right now it is the only theory I have. So, day two everything working, I am going to call Newmar on Monday and find out which fuse to pull to bypass any future false signal so I can at least put the slides out.
If anyone has any other theories on this interesting dilemma I would be curious to hear them

Thanks in advance for any responses

This sounds a lot like an issue Newmar had about ten years ago when they accidentally connected the wrong wire in a bunch of coaches. Here is the TSB related to that. Perhaps it is a similar issue?

I contacted Newmar today and they indicated that this issue is one of those things where the coach has to be in the shop and the techs can see that the ignition 'on' is 'stuck' on to figure out what the problem is..... I understand this. They also indicated that if this happens again to disconnect the positive wire on the chassis battery for about 20 seconds and this may or may not work. I also had the local RV repair guy tell me that there is a wire under the drivers area that sends the signal to the RV components that the ignition switch is 'on' and sometimes there is an errant electrical impulse that sends a false signal....... don't know about that
