Re: Both sets of batteries are dead - solar charge? Reply #50 – March 01, 2018, 09:26:17 pm Fred,Have you checked the start solenoid that is hid behind the kick panel in front of the passengers seat? If dead this could be your start trouble along with no dash power. Here is a link to a thread with pics. to what you are looking for if you don't understand what I am talking about. Nothing happens when I turn the ignition switchMike Quote Selected
Re: Both sets of batteries are dead - solar charge? Reply #51 – March 01, 2018, 10:06:18 pm That may be it since I hear a clunk behind that panel when I go to start it. I am heading over there at 7:00am tomorrow. It that part typically available at the normal local auto parts stores? Quote Selected

Re: Both sets of batteries are dead - solar charge? Reply #53 – March 01, 2018, 10:12:39 pm Fred,Take your volt meter and check to see if the solenoid is passing electricity through it before you just replace it. It can clunk and still not pass current through. Yes some parts stores will have a suitable replacement.Pamela & Mike Quote Selected
Re: Both sets of batteries are dead - solar charge? Reply #54 – March 02, 2018, 10:48:18 am I had a bad ignition solenoid, the dash lite up when I turned the key on, the coach would turn over, but the solenoid dropped out while the starter was still running, killing power to the computer.Coach would start / stop at the back. Only did it after the coach warmed up.Chris Quote Selected
Re: Both sets of batteries are dead - solar charge? Reply #55 – March 15, 2018, 12:51:59 pm I am still not any closer. I replaced the ignition solenoid but I don't think that is the issue since I am not getting the right voltage there. I only get the dash lights with the boost on. I don't think any engine battery power is getting up front. I do have the engine batteries charged and sitting at 12.6 volts. They were 12.7 before I left for 9 days. I disconnected the engine batteries to preserve the charge. My next step is to clean all of the engine battery connections and check each battery when the cables are off to make sure each is at 12.6 volts. I checked the chassis ground cable and it is screwed tight to the frame. My house batteries were drained again. Something is draining them even with the main switch off. The house batteries are really secondary to getting the engine started! Quote Selected
Re: Both sets of batteries are dead - solar charge? Reply #56 – March 15, 2018, 01:45:06 pm Yes, clean posts and terminals and use a flat file on both sides of the cable lugs until they are nice and copper all the way across the surface. Boost solenoid will run down all batteries if left on. Check isolator connections and then use a digital voltmeter there. Salesperson switch on?I ran an extra ground cable from the batteries to a frame member a foot away. Pierce Quote Selected

Re: Both sets of batteries are dead - solar charge? Reply #58 – March 15, 2018, 02:20:02 pm Here is a good starting point for your engine batteries. Only takes a few minutes and a few bucks to fit stainless hardware and clean the posts and cables. Batteries are always the first starting check point when you have a problem. Melted terminal is what happens starting at high altitude with no blockheater and in the teens. It did start but...Use a label maker to identify cables BEFORE removing them. Goes double around the isolator. Ours was badly mis-wired. Chuck, our breaker is located on the main 12V bus located under a cover in the wet bay. Good point to check breaker there plus make a voltage check. The house and engine battery cables are within a couple of inches of each other.Photos #1 and #3 have the wrong description.Pierce Quote Selected
Re: Both sets of batteries are dead - solar charge? Reply #59 – March 15, 2018, 03:58:44 pm You'd think his coach would start at 12.6, ours has at 12.8 after 3 days on the hook with no recharge. I'd be curious as to the make/type/age of his batteries. Here's ours at full charge: Quote Selected

Re: Both sets of batteries are dead - solar charge? Reply #64 – March 15, 2018, 04:41:50 pm Here is the PDF for your coach's 12V electrical system. I suggest you download them, take them to a print shop and let them piece the left and right together and then blow them up to their largest size. Easy to then trace from the batteries forward to see where the problem is. After using the schematic, roll and store in a mailing tube in an overhead compartment.Pierce Quote Selected

I did get my flat file and a terminal cleaning brush and gave all of the battery cable connections a good cleaning. I turned the key and the dash lights lit up! I cautiously turned the key and the engine fired up. Yeah! Now the generator and the engine are running!Thanks to everyone for the help. Going forward, I am going to disconnect the battery cables when parking it in storage until I get a switch installed at the coach and engine batteries just to give myself extra insurance!

Reply #66 – March 18, 2018, 09:26:25 am Fred, After cleaning the posts and teminals spray them with CorrosionX or use an electrically conductive grease like this NO-OX-ID "A Special" Conductive Terminal Grease and the reassemble. Everything will stay cleaner much longer. Be sure to check battery connections to make sure they stay tight, maybe once every three months. They do seem to loosen up over time.Remember to start with the most simple solutions first. Quote Selected
Re: Both sets of batteries are dead - solar charge? Reply #67 – September 02, 2019, 09:58:50 am UPDATE 9/2/2019The engine batteries are fine as long as I keep the terminals clean. I did end up replacing the old AGM house batteries with new batteries. The house batteries STILL drain even though I am flipping off the salesman's switch. The new batteries are good. I had them re-tested and they are fine. My current solution is to physically disconnect the house batteries when I drop it off at the storage facility (no shore power option is available at the storage center). Here is my plan:Step 1: Install a disconnect switch directly at the house batteries to prevent the drainStep 2: Figure out what is draining my house batteries in storage with the master (salesman's) switch in the 'off' position.What items on the coach bypass the master switch? It is frustrating that something it draining the house batteries! Quote Selected

Check out your B-2126 print as there is several things that are on the live buss. Some are the fridge, some of the dash memory, LP detector that come to mind.Mike Quote Selected 3 Likes
