i have a bmw 316i 1987 e30... i recently messed with the ignition and wired in a switch so the car will not start without two keys the main key and my switch key. now every thing worked fine and had no problem starting up, but when i run the wire behind the dash i forgot to disconnect the battery and it touched some where and blew a relay i think so iv replaced the relay but now when i switch ignition on only the battery light shows and none of the other 3 or 4 other lights show i have checked and changed various fuses and relays al matching the old ones and disconnected my switch so all back to norm but i still have no power what so ever i looked through out all relays wiring both round the steering collum other wires it runs if push started but not with the key PLEASE HELP ME ITS BUGGING THAT MUCH I WANT KILL MYSELF!!!

Looks like you might have blown the light bulbs in the cluster. Take the cluster out and test each bulb for continuity with a multimeter.

Sounds like fuse 10 is blown. Car doesn't normally start when it's gone though as it's part of the inhibitor switch circuit for the automatic gearbox.

My only experience of this is finding out which wires to bypass to start an auto to manual conversion.
