![]() That can be why there are occasional failures of the BCC circuit board. If you disconnect the batteries and the coach is parked out in a bright sunny day, the solar panel can put 18-24 Volts into the BCC circuit board because of the lack of battery load to charge. Never work on the (B)attery (C)ontrol (C)enter with out disconnecting the shore power cord, all batteries and removing the roof mounted solar panel fuse (FIRST) in the BCC. Yes, the solenoid switch in question is just like the old Ford solenoids. One would be lower then the other with the engine running as we talked indicating no or poor connection through the solenoid. Since this is a common problem I was watching it closer then usual and caught it before it went clear dead on our 2003.īy the way another way to verify the solenoid is the problem would be to use a digital volt meter and check the voltage to ground on each of the two heavy terminals on the solenoid switch. Anyway if you have the problem you now know where to look. The S 603 runs $34.99 as opposed to the Fleetwood copper part for $52.00. I have fixed ours temp both times by just engaging the jump start switch rapidly several times. The solenoid is the same one that engages when you use the push to jump-start switch. ![]() I have noticed the chassis battery low twice now and it is hard on the battery. It has silver plated contacts and will not deteriorate so easily. The cure is to get number BWD-S 603 solenoid from O-Reilly's Auto Stores. They use a cheap copper contact solenoid that corrodes quickly when engaged for long periods of time. It is engaged automatically by the solid-state controller circuit after a short timeout when ever the shore power is on so both battery sets are maintained. The culprit is the starter style solenoid that is visible inside the BCC (battery control center) chassis/coach interface box under the hood or in the top of the propane compartment on newer units. The chassis battery will sometimes lose it's charge while the shore line is hooked up and power on. I don't recall if I told you that our coach is having a problem that also occurred on our 96. If your Jumpstart push switch on the dash fails to work this is likely the cause of the problem, unless both sets of batteries are dead. If your coach batteries go dead while driving this is also the likely culprit! If your chassis battery goes dead while parked with 110 volt hookup, this is the likely culprit! I would check for reset buttons on the two silver colored circuit breakers at the bottom of the picture(below the solenoid). Really can't tell from the pictures, you only gave a picture of part of the box. looking at this picture can anyone give me a idea of where that reset might be? On the schematic it says that there is a reset button on top of the battery disconnect fuse box. its a 2004 fleetwood storm and the battery solenoid is up front in the engine compartment in a big black box with many other fuses. My momentary switch will not turn on my house batteries. Topic: Battery solenoid reset? (UPDATE)))))))))))) RV.Net Open Roads Forum: Class A Motorhomes: Battery solenoid reset?
