Fire !! FIRE !!!!!!

Postby Dave M » Sun Jan 06, 2019 9:05 pm

Hi guys need your help on this one
Been using my D quite a bit with no real problems - always had a problem with headlights - no matter how many times you push the light switch in I only get dipped lights and main beam off the indicator stalk so basically no side lights !
Went out last Sunday ( day light ) came back in the dark - within 10 mins there was a burning smell in the car and a bit of smoke then I lost dipped lights so drove a bit further on main beam - smell and smoke coming from behind passenger seat - pulled in to take a look and a hole had burnt through carpet and an in-line fuse holder and fuse had melted - I have tried to show some pics of the wires and the fuse box - I seem to remember reading something about the fuse box melting and a wiring mod - as you can see from the pics my fuse box has 2 missing fuses and damage where they should be - I’m pretty sure this damage was done before I bought the car and the PO has done some sort of mod - wondering if it was just the cover on the inline fuse come off and the fuse shorted against something ? I must also point out the rear lights - side marker lights and front amber lights all work fine - I have booked car in with my old school Volvo guy next week so any info would be most appreciated- I have a workshop manual ( cheap reprint - photo copy ) with a shite wiring diagram - any more details on the mod or more info on what could be the problem would be a great help for my Volvo guy

Im not sure what the answer is on your headlights, I do know that my own fuse box looks very similar to yours with the same in line fuse holders, I've often wondered if it was worth making a cooling setup with some computer CPU fans to keep everything cool, be interested on peoples opinions of that idea

Is this normal - what does these 2 burnt out fuse holders do - everything seems to work ok but for the lights - anybody think the in line fuse holders are there to replace the burnt out ones ???

yes the inline fuse holders are definitely there to replace burnt out ones, mine has 5 or more that have been replaced with in line ones

This should help identify them Dave:

At least one of them relates to the low beams.

So had the car back yesterday - turns out there was a short on the front passenger side dipped headlight (wondered why it was always dim - just thought it was a bulb ) so that short burnt out the in-line fuse holder which my carpet was sitting on hence the burning smell and smoke in the car - just wondering now what fuse should I use for the inline holders - think I have 20a at the moment.

You must be relieved that it was nothing too serious. This is a good reminder to us all to keep an eye on those troublesome fuses.

Yes but why didn't the fuse do its job and just blow ? And what size fuse should be used ?

My diagram at the start of the thread shows the fuse sizes?

Yes triston thanks for the fuse diagram - but wondering if it should have been a lower amperage after all it looks like the short that was on the dipped light caused the fuse to over heat and melt thus burning a hole in the carpet and my wife vowing to never travel in the car again ( she has since retracted that remark )
But why didn’t the fuse just blow rather than melt - that’s what a few is supposed to do - am I missing something here ? Should I put a 10 amp in ??
