Why the fuse burn and the car turn off , I change the fuse and the car turn on again


It sounds like a dead short somewhere in the ignition circuit or the "main" circuit. If everything else on the car dies (lights, chimes, instrument panel, etc) when that fuse blows, that would most likely be the main fuse you've identified. It's going to be a serious pain to find that short, and I'm sorry I don't have any real leads as to what it could be other than tracing the wiring back. Whatever you do, DO NOT replace the fuse with one of higher amperage... The wiring will surely melt or even worse, catch fire!

Why does my 20 amp fuse blow when the engine is running, but work without issue when the engine is off?


Why fuses blow or how to find short circuits or drains !

(the Park (tail-running) lamps go to up to 20+ places) ... The below covers shorts in the cab box, not the 50-100 amp engine bay fuse box that loves to rust out.

I have a ford transit flatbed and a 15 amp small blade fuse in the cab fuse box keeps blowing while driving when it blows the engine cuts out and when you turn the key to restart nothing happens at all...


Well u will need an amp meter that will check out the current thru fuse with nothing on " multi function" besides the motor running and see if it solves your problem and tell us your current reading .

Efi fuse blows when car strts wher is the efi located


NO YEAR stated (old post)
there is no EFI fuse. sorry,
the ECU has 3 fuses.
FI, Dome, and IG-coil
all 3 run the ECU.
i do know what you ment.
but knowing the correct name makes reading the FSM better.
my guess 2 is you lost the fuse box cover and cant read the names.
guessing year at 91 -95

top reasons.
ECU bad CAPS
shorting fuel pump (they pull 4amps normal) if 10amps or
more they blow the fuse and or causes the ECU to click relays
like mad.

I have a 2002 Toyota corolla T sport 1.8 and have just had the engine rebuilt but it keeps blowing the 15 amp audio fuse under the bonnet, have tried putting a big amp fuse in and still blows. Car starts...


Hi,
Who installed the engine? If you did, check all the Grounds/Earths under the hood/bonnet. If the mechanic/shop did, take it back and have them fix it.

My daughter has a 1998 Avenger as soon as the car starts it blows a 30 amp fuse in the engine compartment which is simply marked ENGINE. After this fuse blows the car will not even try to start the lights...


sounds like you have a short in the electrical system between the ignition and the fuse box. it might be metal to metal somewhere inbetween in the wiring that is makeing the fuse blow out everytime

You may have some short circuits in your wiring, a bad horn relay or horn unit, and/or a bad wiper motor. Hard to tell without actually looking at it.
Try this:
Disconnect the horn, and try another fuse. Does it blow? If not, the horn is shorted, and needs replaced. If it blows, remove the horn relay & try another fuse. Same with the wiper motor, unplug it and try another fuse. If it does not blow, you need a wiper motor.
