converter wires sch

I have a 2002 dutch star gas coach, i leave the coach plug into shore power while at home,this last week both house batteries and chassis batteries went down. the converter has over 13 volts coming out of it,the in side lights will work,have 13 volts going to the battery meter ,but on the rocker switch use to put in use or storage have same volts that is on battery .The converter will charge all my batteries when the system is working.I took out the fuse to the boost switch when i put it back in the sol click and 13 volts back to rocker switch and ever thing is working again.two days ago i put on battery charger ,sol click and charging system work.Is there any place i can get a wiring sch too see where i loosing my converter voltage ?

Are you sure the converter/charger is actually putting out a charge voltage? When the batteries are fully charged you could read 13 volts from a surface charge. Bring the batteries down a Little bit; say to 12.5 and then plug back in and check the out put of the charger @ the charger. If you are getting 13.8 - 14.2 the charger is good and then check voltage at the battery bank. Make sure batteries are connected. Let us know what you find.

You have proper voltage out of the converter (What model please) to the house. but low (Battery) voltage on the USE/STORE switch (Also what model if you can tell me)

Suspicion is: Defective USE/STORE switch and/or Battery disconnect solenoid (#1 in my book is the switch)

#2 suspect is a pair of circuit breakers

My coach, and I kind of suspect yours, has an Intelletec Battery Control System under the hood (yours may be elsewehere) this is a big black box that says "Battery control system" on the cover. Now, I will tell you how MY house is wired

THe converter feeds the fuse panel that feeds most everything, including the volt meter in the BCC's remote panel.

The schematic for the BCC shows two post type 30 amp breakers (Push to reset) in the bottom of the box.. I do not have those, I have a self-resetting breaker (bigger) next to it, but if those breakers have "Tripped" then there is no connection to the house batteries A RESET will fix

IN my case the switch failed.. Oh, "Disconnect" (STORE) worked fine, but "USE" (Connect) no joy.. I will tell you how I fixed it.

To test this you need a bit of quiet and may need a partner depending on where the box is.. Press the switch you should hear a CLUNK, if you don't press "STORE" if you now hear a CLUNK you found it, the problem.

If you do hear a clunk both ways move to the location of the clunk (That's the BCC)

Mine has 3 heavy duty cables, and connections

1: Generator (house)
2: Chassis (I think) or Main
3: AUX (House battery)

Use a volt meter to measure between each of those 3 and chassis ground.. You should see

Generator: Proper 13 volts
Other two, Low voltage

Jumper Generator to AUX.. Hopefully you won't need to also jumper in Main.

Now, back to fixing the switch

Remove the panel from the wall, disconnect the plug on the back, operate the switch 50 to 100 times, both sides, re-connect and try again.. CLUNK/CLUNK (use/store) you fixed it

Switch is self cleaning, and that's how you self clean it.
Home is where I park it!

Thanks for the input ,I think i found where the problem is.The intellitec disconnect relay. Drop .02 volts across relay,tap on relay and no voltage drop.Press the use/store switch several times and no drop across relay.I am going to replace the relay.There should not be any voltage drop across relay.Also the use/store switch in the coach had a small voltage different from the battery volt meter on the same circuit board,after a tap on the relay there both the same.The battery volt meter must connect to the converter side and the use/store switch to the other side of relay.
