So, after issues with the van electrics I’ve decided to strip the wiring out - work out what’s not working and why.
I also wanted to move many of the fittings and re-route most of the wiring and water pipes too as there was no real thought process followed that made best use of existing space.
The battery wasn’t secured, thermostat not connected, (which was why the water heater never turned off), shunt incorrectly wired, (thanks for the dell
@Dellmassive ) and no fuses anywhere. The cabling was neat and correctly sized, and all connections that I inspected good. The water level indicator never worked and the wiring routed through a hole in the floor and not protected, (already worn the outer sheath).
I’ve removed the battery and most of The major wiring. disconnect the bed but this can’t be removed. Disconnected all the water hoses, water heater and pump.
I’ve drawn out my new wiring diagram, but this is somewhat dynamic as I’m not sure how physically this will all work.
I spent a happy afternoon in the garage with some scrap wood making a cover for the battery, providing a place to mount some of the switching gear.
I’m now waiting on a few more heat pads, (don’t rely on the pictures on eBay, actually look at the measurements), more copper, fuses, terminal blocks and connectors.
I have a relay to automatically switch the heat pads on when the temperature drops below 5C.
I’m just making this up with massive help from the forum as I go along, not much else going on!
