I installed a Wirthco Battery Doctor dual cutoff switch with the intention to wire two batteries to the TT. Unfortunately I'm not great with electricity, so if you could answer a couple of questions I'd appreciate it.
If I wire the switch as in the picture below, and set the switch to 1+2, would:
1. both batteries get charged by the truck and/or inverter?
2. the voltage out be 12v or 24v?
I've looked all over the net and can't find an answer. The only thing in the switch documentation says it works up to 48 volts, but doesn't give a lot of info, and nothing about the end results.
Would it be better to run the batteries in parallel and run the single positive out through switch position 1 and only use switch position 1?
