Use amp meter and determine power draw against fuse size. Something is shorting - but if you can determine how much power is trying to go through you can devise a fix.

SOURCE: 30 amp ignition fuse in engine compartment blows at start

It sounds like a bad ignition switch or something is grounding out.Try to isolate the problem to key positions.See if the fuse blows when you turn the key to ACC(when your dash lights come on without starting)If the fuse does not blow then when you go to start it and it blows it could be one of many problems,the more common ones could be ignition switch,wiring,starter relay,starter soleniod,or perhaps the starter itself is shorting out,this can sometimes happen when a starter goes bad.

SOURCE: ignition switch fuse terminal is blowing red 40 amp fuse when i try to replace it

A fuse that is consistently blowing is telling you that there is a short in that system. Don't attempt to bridge it or use a larger amp fuse or you will have a major problem. You will need to start tracing wiring to destinations to find the short. If while moving harnesses around problem ceases to exist, look at nearby items where you are working and try to locate what was grounding. Sometimes people will stop if short disappears, leaving open the possibility of it happening again.
If you are not comfortable working with wiring, then leave it to professionals who do this every day. It's not really difficult but requires patience and a good bit of knowledge to do this right!

SOURCE: fuse keeps blowing

If fuse keeps blowing that means that there is a shortage on AC wiring or switch controlling the air conditioner.

Also an abnormal power draw from AC caused by an internal fault on AC can cause the fuse to blow.
Test wiring and switch with a voltmeter, the most common is that there is a short to ground between wiring and car body somewere.

SOURCE: 2008 Ford F450 fuel pump relay fuse keeps blowing.

the fuel pump and radio are not on the same circuit, most liokely the fuel pump is shorted, that is the most common cause, get under the truck and disconnect the fuel pump connector at the tank, if the fuse doesn't blow then u need a new pump.

SOURCE: 2008 Ford Escape Horn Fuse keeps blowing after

I would trace the wire from the horn and see if it was inadvertently damaged when the alternator was installed. If you have a voltmeter, you can remove the horn fuse and check to see if there is continuity between the horn (non hot side) of the fuse and the car body. This would indicate a short in the wire running from the fuse box to the horn. You can also look around the alternator mounting area to see if any wires are being pinched. Hope this helps. Good luck!

My 2010 chevy malibu ac won't work, the fuse blows when I turn it on but nothing is grounded out could it be a bad compressor causing this?


If the fuse blows, unplug the compressor wire to the clutch and replace the fuse and try again. If the fuse doesn't blow, the compressor is the problem. If the fuse blows suspect a direct short in the wiring from the relay to the compressor

No voltage to fuel pump


A fuse will blow for 2 reasons . 1) If the device has a Short in the circuit that runs through this fuse. 2) If the device draws more amperage from the power source through the fuse than the fuse will handle. ex. if a fuel pump or starter has a 20 amp fuse and the starter/fuel pump is going bad and draws 30 amps it will blow the fuse. A fuel pump on a 1996 vehicle is located in the fuel tank and is kept cool by the surrounding gas and the gas that flows through it. Overheating a fuel pump is virtually impossible. That being said there is a High probability that replacing the fuel pump and relay will fix this problem. It is quite common for this to occur in the GM vehicle of 1996. When the pump starts to fail, it draws an excessive amount of amperage and would blow the fuse. Hope you find this information useful.

If your phone is drawing more amps than your fuse is rated for, then the diagnosis is correct. If you are plugging it into your auxiliary power port try increasing the amp rating of the fuse. IE; 15amp to 20amp
