I changed the original fuse (which is working thermal and therefore not apropiate for the engineroom) to a switch/fuse from Carling Technologies which is working hydraulic magnetic.Sorry but I have the papers in germany.
I bought one from SVB and one from the German Dealer .
Easy to Change, fits in the original place, only the hole in the front should be a little bigger.
Since changing no more trouble.
