I need some advice here, as there is no guidance on this by the supplier:
I have the Bus Manager, Two batteries, B&C main and stby (vacuum pad driven) alternator, both with external voltage regs, LR-3D.
The drawing depics the current situation:
The Main Alt supplies power to both busses and battery 1.
Battery 2 is charged by the STBY Alt. To get that, the Bus Sense is picked-up at battery 2 positive terminal.
The problem I have with the current setup is that, when I depart with a weak Batt2 (I know I shouldn't), STBY Alt goes up to its limit of 40AMPS to charge the battery. I don't like this since I have no blow-tube on the alternator and am fearing overheating it.
I am looking for a setup so to let MAIN ALT to charge both batteries and save the STBY as a real backup, but I think it isn't possible considering the diode setup in the Bus Manager.
Anyone can share how they hooked-up two batteries and two alternators (with ext volt reg) ?
Please note that the blue diode in the schematic is removed when installing dual alternators.
