Outer Limits 4x4 Board

well as said im having problems with my engine fuse. I diont have a manual and im just wondering what else runs off the same fuse? So far i know engine,dash lights, instruments, indicators. It has only ever blowen in reverse so im wondering if reverse light is on the same fuse? Is there anything im missing. Its only a 15a fuse and that seems a bit small to be running all that but that is what the cover says its supposed to have. It is an 85 dual cab diesel. thanks in advance.

I had the exact same problem, the reverse lights do run off the same fuse. underneath the gearstick there is a smallish loom, of which i had a wire rubbed through to bare wires, everytime the wire touched the body, bang, the fuse went. It took me 2 weeks of searching, cursing and hoping to find it before i got an auto lecky to find it and less than an hour after he turned up he was driving away.
