It's a pleasure to find such a vibrant community of folks with Airstreams.
It's unfortunate that my introduction to this forum wasn't possible without the woes of vehicle troubles as the catalyst.
So straight to the point... Can anyone identify what the following solenoid/items are, and what their function(s) are?
The back story is as follows:
I have a 345 LE motorhome that was weatherized and stored for the past year. Upon an unsuccessful attempt to start the vehicle, the battery seemed a bit weak, so we put it on a charger for a bit, and the next attempt, about an hour later, turned the engine over like a charm. While the moho warmed up, we walked around, checked tires, fluids, opened windows, etc.
After 40mins or so, turned the engine off, checked the Transmission fluid, and minutes later, attempted to start the vehicle again (to turn the wheels and crawl under to check the brake fluid.) Now the vehicle wont start.
I go and check the stats dashboard, flip the switch to "Coach" and pressed the something-button and it displays a reading (partial charge, nothing out of place.) Next, I switch to the "Auto" battery, and press the button, but nothing, not a glimmer of back-lighting appears. It's as if there's no power to the dash when trying to get a reading of the smaller battery. There are, in total, 1 battery as described below and 2 deep cycle larger batteries.
So, I can turn on and run the Onan generator using the dashboard and smaller battery, but cannot start the vehicle. When turning the ignition, the starter seems to be engaging but just without enough juice. So I think it's a bad battery (only 1.5yrs old,) and return it to Les Schwab to get it tested. It tests fine at: 760 Amps (800 rated), 12V
, just a little discharged. So it's back to the vehicle, FYI, I have installed lever disconnects at each of the batteries for when in storage, but now tried to think of what the problem might be.
I'm thinking maybe it's the starter (I'm not really drawn to this conclusion though,) rather, it feels like the starter is just not getting enough amps.
Maybe it's something electrical (worried) but where to start.. that's when I took the above picture to start tracing the problem.
As a note: I do have a booster switch in the glove box on the dash, I suspect one or two or more of the items in the picture are a part of that system. And I do not know of another disconnect switch in the system. The prior owner did not mention of one when I purchased it. But would the booster switch and related solenoid(s) even contribute to this vehicle-will-not-start problem? And the generator does not seem to be impeded from starting on that battery. Also, I have the manuals but not where I'm at for the time being.
Any help would be appreciated.
