New one for me (involves fire)

    So I took the car for a spin yesterday and as I'm arriving home I notice a burning smell, I knew it was electrical, knocked off the ignition. Under the dash was fine, so i popped the bonnet and found an in-line blade fuse and it's rubber holder on fire!! :eek: Disconnected the battery and it went out, then cut out the fuse holder (was for the electric fan) which was reduced to carbon. Thankfully the damage was limited to the fuse holder.

    The only thing I can think of was that it suffered catastrophic mechanical failure (ice damage/caught in the belts) and then shorted out, but a fuse and it's holder going on fire, that is a new one on me! Has anyone else heard of this happening?

    (keeping an eye on my fire extinguisher, in case it bursts into flames)

    its an electric fan you say..does the fan still work.? was the fuse too big ? causing the holder to melt rather than blow..

    I cut the wire out, so the fan doesn't work at the moment and I haven't had a chance to test it. I've had the fan for five years, but I'll test it's operation ASAP

    Just a guess, but maybe the fan motor siezed. If the fuse you had was too big to blow, this would cause it to go on fire.

    You might be correct, earlier in the day I had to apply some pressure to the fan to change a belt (there is very little clearance between the water pump pully and the fan motor), perhaps the blades got jammed and as you say the fuse was too big.

    I have been told a few times that the "cheap" assorted boxes of blade fuses are dangerous because they dont blow, but melt and burn.
