Dual-battery, onboard smart charger

[Fastrat]

By “the wire” do you mean the the red small red wire on the back side of the DVSR module?

If the above is true, and this red DVSR wire is landed on a bus from the switched side of the start battery switch the DVSR will be active whenever the start switch is on, not just when the engine is running.

Can you provide a diagram illustrating what your wiring would look like?

Same diagram as above, simply cut the DVSR wire and splice it into the engine side of the start switch. As it is wired from the factory, it would be on without the start switch closed (ON)…this method would make it on without engine on and when off (in storage) then battery chargers could maintain each bank separately…if I’m understanding it all correctly. I'm prolly overthinking it though...I might just move the start battery sensing DVSR wire from the battery side to the engine side and call it a day to separate them when switch is in off position. I may send BEP an email to ask, just in case though.

Edit: lol, thanks to FSH210, I see what you’re saying now and I’m obviously having a multi-day brain fart…that won’t work as it just completes the circuit.

Just wire it to the switched / load side of the start battery switch and be done with it..that will make the dvsr active when the start battery switch is closed, and inactive when it is not and when you are charging batteries with the onboard charger.

No worries, that is the main reason we post and ask questions..

Get that done and go out and burn a lot of fuel!
