Thank You JA this is not my field of expertise so I will get the professionals to have a look at it.
You have been very helpful and I thank you but have to admit i get lost in your answers.
The other fuse that i bought just has 10 pounced on the end of it and that is it, they look the same but are probably very different.
I will follow your advice and check out what I can and if no result consult someone that knows what he is doing.
