We were originally introduced to JJ's landcruiser a few years ago when he was having issues with his dual battery system. He was having intermittent issues with his switches not working, solar not charging and the battery often going flat.
The first stage of this build was a wiring tidy up and install a customer supplied shunt for battery monitoring and an inverter capable to run an induction cooker off his ATG lithium battery.
We weren't quite expecting to see the birdsnest of accessory cables behind the panel in what otherwise was a clean and well built tourer.
we found a heap of the existing cabling hadn't been fused, and quite a few burnt out accesory cables, so we spent a but of time re-doing those parts that couldn't be salvaged, and cleaning up the panel for any future modifications or fault finding.
