Will be installing a 40W DC charger in my caravan, to bypass the GC smart alternator. Power to be sourced from the GC jumpstart terminals using 8 gauge wire and 60W fuses.

My vision is rather than the traditional 2-pin Anderson Plug change to a 3-pin Anderson on both the GC and caravan. The third pin/wire being the isolator so that the DC charger stops functioning when the engine is off so as the GC battery wont be drained if remaining hitched up overnight.

A well intended person suggested wiring the isolator cable into the cig socket near the tail gate. Not too sure about this. Interested in hearing from anyone undertaken something similar, particularly locating/attaching the isolator wire.
