***Link Removed***That sounds correct as many battery control centers do not have the capability to charge chassis battery from shore power.
I run a jumper between the two positive terminals to charge chassis battery.
Is this your model?
Some battery control centers have what is called a BIRD set up to charge batteries. (bi-direction relay)
Yes that is the manual, which I have, As you see on page 2 if either set goes above 13.3 volts while charging the isolator relay (solenoid) pulls in and both sets should charge. This is what it has always done from shore power, from the alternator, from the generator, from the solar panels, etc.
They also say this on page 7, which I do not completely understand?
"If there is voltage on the coil, check for voltage between the main and auxiliary batteries. If the voltage is more than 0.1 volts replace the relay."
I think they are saying that naturally when the isolator relay is pulled in voltage should be the same on both sides?
I would also assume that if the isolator is pulled in, as I can hear the loud click as described in the manual, I should have continuity across the other two terminals on it? I just wish there was a way to checking without pulling out the circuit board as all the disconnects and isolator are behind it.
