Battery and Alternator schematic
Posted: Mon Oct 26, 2020 8:00 pm
Hello all!
I'm working on the details of my Onex schematic in small bits. Drawn here is the battery and alternator portion of the circuit. I'll add the engine ignition circuits next, and then the main bus and beyond. I'm looking for general feedback. I have a few specific questions also.
1. Should the regulator contactor coil be powered from Vout of the regulator (as drawn), or the battery? Does this matter?
2. I have the master configured as off-batt-both. Is that reasonable, or should I use separate switches so I can also isolate the battery and run from the alternator only?
3. I'm not really sure of how the alternator/regulator circuit may fail and where to place the contactor.
a) as drawn, the everything is protected from a failure of either (alternator or regulator), but I've heard the alternator can melt down the regulator and do some extraneous physical damage.
b) if the contactor is instead between the alternator and regulator, a meltdown could be prevented. In that case, however a failed regulator might short the battery to ground. Can that happen?
