Battery Control Center Question

I have a gremlin. On my bcc chassis battery relay, when I try to turn on the battery from the panel, I can hear the relay click but when I let go of the switch, it drops out. I will sometimes, infrequently, hear a second click and it will stay on. When I start the coach the relays come on and stay on. Everything works fine when the light/relay does come on.

I can't figure out why it wont stay on when I try to turn it on from the panel. Anyone have any ideas?

Hello Gdonahoo and
I am assuming you have already checked the battery state of charge with a volt meter?
You might want to include a little more info about year, make, and model of your coach.
I am sure someone with more experience than I will be able to steer you in the right direction.

I have ran across loose connections on the main cable lugs that can cause your scenario. You will have to remove the top circuit board to gain access down into the guts of the BCC. Good luck and let us know what you find.

Need make and if possible model of BCC in order to try and download service manual so i can read the beast.

Possiblities include bad relay, bad switch, short in wires, and "other" lots of Other.

Dropping out suggests that there isn't enough voltage present to keep the holding coil energized. I very seldom use the battery disconnect switches cause I keep the moho plugged into shore power.
If the coach batteries are up to snuff you either have a bad relay or a converter that isn't keeping the batteries fully charged. As RVWizard suggests, there may be a loose connection at the relay in the BCC. I've replaced relays in the BCC and it takes a little bit of disassembly to reach the relays and removal of the large buss bars connecting
them inside the box. The best relays to purchase come from intelletec and you can locate them on the web. The BCC in my coach, a 2000 bounder is probably the same as yours. It isn't rocket science, just takes a little basic DC knowlrdge and make sure you remove the terminals from the batts and unplug shore power before you attempt to remove the circuit board and the buss bars.

The disconnect relays (solenoids) in the BCC are latching relays (no holding current required). If the relay drops out when you release the switch you have one of the following problems:

1- A relay that won't always latch internally (it's a simple magnetic/gravity latch mechanism)

2- Sticky or bouncing contacts in the disconnect switch.

Try releasing the switch very slowly and carefully. If it continues to be troublesome you may have relay problems. They are repairable, but probably should be replaced.

The disconnect solenoids are held in the connected position (with the ignition on) by circuits on the BCC circuit board and don't rely on the mechanical latch function, so your problem would appear to be one of the above.

Do you have the BCC made by RV-Custom Products or the Intellitec clone.

I have diagrams and trouble shooting procedures for both if you are interested.

Loulong is correct, the battery disconnect relay is a latching RELAY and only requires power to activate afterwards it remains latched if it is not malfunctioning.

Sorry about the earlier post, but it appears the relay is bad as loulong suggests, and I think he is correct.
