Pulled coach out of storage 3 weeks ago and would not start without boost. Customer service suggested solenoid since batteries a year old. Ordered and got recently but not installed waiting to get to another location. Batteries charging when driving and I turn them off when stopped. Today plugged into 50amps, got heater module fault. Started generator and cleared fault. Toilet stopped flushing. If I start the engine all the actuators on cargo doors start chattering. Interior lights flickering. House batteries also year old and agms.
Any assistance would be appreciated. I am not electrically inclined.

Need to check all battery connections and especially grounds.

Tom, thank you for the reply. Strange but found 3 cables off of one of the house batteries. I have never seen this before since owning 7 coaches.

When you say "off" do you mean disconnected or 3 wires landed on one post?
They are hooked in series so 2 = 12V. How many batteries do you have in that bank - 4? 6? 8?

I have 8 batteries and 3 cables were totally disconnected. Could not find the bolt or lock washer initially. After searching the compartment, found and reattached cables and bolted down again. I also found another cable loose. I will monitor from now on.

Did you have your coach stored 'professionally?' By that I mean, did you drop it off at one of those non-self service storage outfits that you cannot drive and park your rig yourself? It would be highly unlikely that three cables would just jump off their poles by themselves - unless you are doing a bunch of high speed, off road RV'ing. Maybe they routinely disconnect the batteries for their clients to avoid discharge?

Coach was pulled into covered storage by myself. All bays were locked.

I had to put star washers to keep my cables from coming loose, i do have dielectric grease on them for corrosion preventative. I think with the grease on there, vibration from the nearby diesel motor was loosening them, no issues after the washers.
