Dashboard Alternator light
Hi all, The MPPT controller on my coach will deliver 14.6 volts in bulk mode which is fine. In fact it’s exactly what the specs on my GC2 house batteries call for. But when I turn on the engine and...

This is the manual for the Intellitec Battery Control Center.

It's too complex for me to mess with but the bottom line is that it allows any charging source, ie solar, generator, shore or alternator to flow to all batteries as it deems necessary. And it will pass high voltage and big amps.
From that manual
It would be nice if I could disable the chassis battery charging from the solar while the alternator is running but I'm not that smart. I'm going to study the wiring diagram but this is not my line of work.
I wired a solar system up with a battery management system similar to yours without any issues. I also installed a Trik-L-Start to charge the chassis battery to that MH with no issues, but that thing is very low amps. I also installed a Trimetric in that MH with a wire allowing me to read the voltage of the starter battery. (The Trimetric is a better meter than the Victron, BTW, but that's another discussion).
I will investigate the dash boost switch. There's a possibility it's wired wrong. I can also disconnect the starting battery voltage sensing wire from the Victron, but that thing is tiny. It's also a 10 sec job so I'll do it.
I've got a question posted on a Ford Truck forum right now about the dashboard charging light behavior. That is, does it signal over voltage as well as under voltage and it so, what is the threshold.
Unfortunately, I can't get the MH uncovered until at least a week. It's too **** hot here.
Thanks for your help/interest,
Eric

From that manual
The charging circuit, (which utilizes an isolator solenoid to connect the two batteries together for charging) will charge both batteries if either battery is being charged. It operates by sensing the voltage on the main and auxiliary batteries. If either voltage goes above 13.3 volts (the minimum necessary to fully charge a battery) for more than about 14 seconds, the isolator solenoid will pull in, charging both batteries. If the voltage falls below 12 volts for more than 4 seconds while the ignition is on, the isolator relay will open, keeping all of the alternator's output available for the chassis functions. If the ignition is off and the auxiliary battery voltage should drop below 12.8 volts (voltage of a fully charged battery) for 4 seconds, the isolator relay will open, preventing the coach loads from discharging the main battery.
