sounds like poor earthing so the cable is acting as an earth Cable. DO NOT IGNORE I had to completly rebuild a mates wiring harness, after it melted due to someone forgetting to refit the earth cable after a Transferbox swap.. He was lucky that the whole car never went up in flames.

I had a similar problem on mine, caused the handbrake cable to become the earth cable, started a fire at the handbreak lever, thankfully the driver put the fire out in time but it still managed to burn through the cable

Had exactly the same problem on my defender , and it was the earth cable. It also stopped my battery being charged as well. It might just need a bit of wire brushing or tightening of the connections , that fixed mine!

i had a similar problem with releasing the hand brake,the panel lights would dim,using indicators would cause any lights on to "flash".
anyway i rebuilt my o/s front wheel arch and found a soldered earth terminal on the lead that should have been bolted to the panel and then on to the chassis.
this done and seems to have solved the problem.
