Hi, my sister-in-law has a 99 Reg Ford Fiesta 1.25 and the dash lights, LH tail light, RH number plate light and reverse light have all stopped working! Every time she Switches the lights on the fuse blows! Also every time she turns the ignition on my Engine Management fuse blows! No idea whats going on! Can anybody help please?!

ive said it could be the fuse box, but i don't really knoe what im talking about, Thanks in advance!

 

what circuit does the fuse protect?

 

what do you mean, ive said all that i know, its the sister-in-law's car, it's not here, why would the engine management light fuse blow, i don't think it's worth fixing if it's the fuses box is it

 

well that fuse clearly protects certain items on the car so once find that can start to look at certain wiring or components etc

 

Could be many things, bad earth, poor connection, damaged wiring, broken wire...

It's not the answer your looking for, but the best thing is to have a good going over of the cars earth wires, lights, make sure all the bulbs etc are correct and fitted correctly, check the rating of the fuse is correct and not just a replacement for what was in there as that could be wrong to start with.

 

Quickest way to check is to disconnect the circuits that aren't working individually i.e rear lights first,try the fuse,reverse light switch,try the fuse etc so it may then show which circuit is blowing it,if your lucky and it's the reverse light switch just leave it disconnected but obviously if it's something a bit more important like brake lights etc then you may need to rewire them.
I'd say though it's most likely the fuse box as its really common on them although it's pretty easy to change like for like and you could get one from the scrappy for a tenner,worth a try.

 

thanks guys will copy and paste answers in a email

 

The fuse is supposed to protect the wining so you do not get an electrical fire! from what you say I suspect part of the loom has been squished a bit or gone rusty. try one a a time and see what blows!

PM me if not too far from Manchester!
