I just bought a couple of them today from the stealer. I didn't know if regular parts places carry that type and they were only a couple of bucks a piece. Part # is: N-017-125-1 50 amp fuse
Not to hijack this thread, but I had a similar problem today:
While trying to figure out why my Jetta wouldn't start this morning I figured glow plugs and started looking for the fuse. Bently wasn't much help and I found some web sites that mentioned that it was located near the strut tower. I looked and sure enough there was one of them fuses right by the strut tower and it was corroded to the point that it was in pieces. I stuck a piece of wire inbetween just to make sure there wasn't something else wrong and it didn't do a thing. So then I was thinking relay and while searching for the relay I found the little black box on the firewall with the glow plug fuse. That was corroded to the point of there being nothing left as well. I stuck a wire in there and viola!!! Car started perfect.
I later found out that the first fuse I was looking at was for the fan controller. After replacing both fuses with real ones I sprayed them with some of that battery terminal greasy paint stuff to hopefully keep them from corroding away again.
Question for the gurus: After cranking for quite a while this morning due to no start I hooked up a remote starter switch to get power directly to the gp bus bar and it fired right up afterwards, but it made a hideous sounding racket for like a 1/4 - 1/2 second that sounded like valves hitting. Is it possible to essentially hydrolock a motor by cranking it for a while and not having it fire? Was that noise indicative of something bad? It's been running fine since, but that noise did not sound good at all.
