I've just had a slight problem with the car. There was a short on the central locking system and the fuse didn't blow. Long story short, smoke in cabin, warning lights everywhere.
I've had an electrician out and took a quick look at it. The wire for the central locking is completely burnt out, and in doing this, it has melted the plastic of some other wires in the loom, essentially gluing wires together (and most probably causing other shorts which caused the warning light etc).
I've traced the burnt out wiring by taking the seats and carpet out and I'm contemplating replacing it myself. Is this a good idea, or should I get a brand new loom fitted (this is probably write-off costs as the car's a 97 model and possibly only worth about 2 grand), or will it be OK if I go in and just start replacing individual wires? If replacing wires is fine, is it OK just to snip out the bad bits and solder in new sections and electrical tape/heatshrink the joins? If I am to do this, what guage of wire should I be using?
Edit: If it is a write-off, presumably I can sell the car for something to someone as it's only the wiring loom that's knackered. The rest of the car is fine! It's due an MOT in August so this is why the write-off is looking a possible option.
The short started in the driver's side door and then from there, the burnt out section goes into the cabin, underneath the dash. From there I lost where it went, but it looks like goes to the passenger side. The passenger side wire is burnt out all the way from the fuse box behind the glove compartment down to underneath the passenger seat, where it goes into a connector with other wires and stops.
Edit2: Just spoken with the sparky again. He's saying that if I replace just the burnt out wire, I can separate the other wires where they've fused together and then just insulate them with electrical tape. Is this a good plan?
