I see your old post about the serrano BCC. My problem is when I shut off the coach (about 1/2 the time) the coach battery disconnects. The 100 amp breaker trips. The little button on the grey relay is okay I think. It doesn't click when I push it. Could that relay be my problem? I've been to several "professionals" and no help. Where can you buy that little grey relay with the reset? Thanks, Jeff
