Fusebox on top of Battery..

a very common problem with mk4 golfs,the black wire runs to the altenator and is very prone to high resistence ,it heats up and on most cases melts your fusebox on top of the battery..

i got mine repaired for a few dollars at a local garage..

as a backup i got a full cable made up as it could return to melting my fusebox and its easier to just replace the cable than a box every few months..
