When you are on the hook for weeks you need something like the Balmar Duo-Charge to charge the starting battery when the alternator output is trying to put that 100 amps back in the house battery. krj No, then you need a switch between the two batteries marked ON-OFF to parallel everything for charging when the engine is running. A remote full-duty-cycle relay with a little switch up by the engine controls is nicer. Put a pilot light on it to remind you to shut it off when the engine isn't running. Switch or solenoid + contacts + House Batteries-----|----------| |-----------|-------Starting Battery | |switch at engine control | | Alternator |--solenoid coil-|-(gnd) DC output |---ind lite-----| Crank engine flip switch Charge everything flip switch Shut down engine KISS....?? We got 2 alternators, but I still have a cross-connecting switch so I can charge everything from the one working alternator that's left. The big house alternator failed 90 miles S of Charleston coming up from Florida. I flipped the switch ON and noone noticed...(c; The damned fancy multistage controller failed. The Perkins alternator pulled the load just fine for the rest of the trip. How did you mount a second alternator on the 4-108? |
