Electric Land Rover Defender 110 Repairs

Just some clips of a small project I'm working on for a friend. His electric Land Rover Defender 110 died and has been sitting dead for more than 8 months now. 12v keeps dropping extremely low and the pre-charge circuit isn't working, contactors won't close, so it won't move. It also needs some other minor updates...new throttle pedal, install a 12v gauge, cleanup some of the wiring under the hood and dash along with other little odds and ends.
