I have a Balmar MC-614 voltage regulator, and since I re-wired my alternator so that it directly charges my batteries (i.e., not through the same cable that goes from the batteries to the starter), I realized that it’s powered on all the time. I did as MaineSail suggests and installed a Service Disconnect switch when I rewired everything, and the two wires (terminals #2 and #9) from the MC-614 are connected to the alternator side of that switch. From there, the positive cable goes to an “always on” positive bus, and then to the batteries.
Here’s my question: is there any reason not to wire the MC-614 to a relay, so that it’s only powered when I turn on the engine panel? I know it probably doesn’t consume a ton of current, but I still don’t like the idea of it being on 100% of the time. I already use a relay that’s powered by the engine panel accessory circuit to turn off/divert my wind generator when I’m running the engine, so I know it could do the job. Is there any reason not to do this for the voltage regulator?
