Morning All,


I recently had to change the hurshmann plug in my Jensen, but now it’s starting to heat this black box right up?


I did replace the plug with a big standard one and not one with a red led light? Don’t know if that makes a difference?


Any ideas?

Bad earth = higher resistance = heat .
