[Danthehollowman]

Had a small engine bay fire killed fuse box. Replaced fuse box checked connections and had to cut handbrake cable after it welded itself solid. Truck all good but when go over a good bump all electrics go off for a split second suggestion bad connection or damaged wire but can i find it? Battery connections all lives and earths in engine bay fine. HELP?????????

300tdi disco. The small live from battery rubbed thru from vibration and earthed the complete truck lots of smoke. fixed all that in the nick of time was going to claim insurance till i noticed what had happened but still got this niggling fault

not sure if if 300 is the same as 200 when it comes to the wiring but i had a 200 years ago that did the same thing. turned out to be the fusable links in the loom.
Do a search on here some thing will come up

Don't know the background to your fire but I've heard that welded/sticky handbrake cable is often a sign of a poor earth to the engine....sure I've read it on here somewhere....anyway you probably know all this but if you haven't checked, it may be worth double-checking.
