What did he do?
When I was an apprentice a mate rebuilt a Land Rover using the facilities of the material stores and replaced every bit of aluminium. His conversion to run it on Calor gas needed my assistance, as he was drawing off the gas so fast that the gas bottle was freezing. My solution- get a reel of 23/0076 wire, wind the cable round the gas cylinder and slap it across the battery. Eventually we worked out a control system (a switch) to stop the battery going flat.
