The most common cause of this issue is a shorted to ground engine harness, due to engine movement the harness rubs on the engine and shorts out, I hear this issue fairly often on the Toyota pickups. look in places where the harness goes over or around engine components, the problem will be there.

I have a 2003 mustang gt that keeps blowing my 30A maxi fuse and it cranks but won't start


You will have to cover every circuit that fuse protects, until you find the shorted device, motor, component, or the wiring with it that may be shorting to ground. A maxi fuse can be for a particular heavy draw, like the headlight switch, or rear defroster, or it can be a power distributor to potentially many other circuits, which may have their own smaller-amp fuse to protect the individual circuit. In short, you badly need a wiring diagram that shows that maxi fuse and all its dimensions.

You may find some help here with a wiring diagram. http://www.bbbind.com/technical.html

Go to TSB's & wiring diagrams, agree to end user license agreement, next pg. click on wiring diagrams, and enter vehicle information in the drop down boxes. Look for diagrams under Electrical Distribution, subsystem- power distribution. You can start there, lots of wiring diagrams for every system on your car. It is a huge free database for every car (almost) going back to 1986.

Why does AM2 30 watt fuse keeps popping on my 1999 toyota tacoma 2.7


fuses keep blowing because the current flow exceeds the rating of the fuse . That means that something is shorting out . Find the circuit that the fuse protects and check the wiring for dead shorts or a unit that is shorting out internally.

Could be a short circuit on ignition wires or a broken ignition switch. Or a short circuit on starter wires or inside the starter motor itself.

Need help?


What kind of car do you have? Is the problem consistently experienced when you try to shift? Generally, blowing a fuse means that you have a short to ground in that particular circuit. Make sure that you are using the correctly rated fuse for the circuit. You will need a wiring diagram for the specific vehicle that you have, in addition to a multimeter to begin diagnosing the problem.

Why does me AM2 fuse blow on my 96 camry le 2.2


There is a capacitor/condenser that is used for noise suppression/static. It is attached to the post of the coil. They melt and short out blowing the AM2 fuse. You can clip the wire for now and it will run fine. The condenser can be purchased at the dealer for about $8 but the distributer has to come out to change it.

Nissan pulsar 2000 model no tail lights working fuse keeps shorting out can i get a wiring diagram off the internet


Before getting too involved, first remove all the stop and taillight bulbs, and see whether the fuse remains intact. It may be necessary to remove the front clearance bulbs as well.
If the fuse still blows, carefully inspect all the bulb sockets for signs of wires touching. Repair anything you see.
If I remember right, there is a set of connectors within the boot (trunk) of the car. If the problem persists, disconnect all of them. Try the fuse blowing bit again.
If it still blows, the problem must be between the switch and the rear.
If you have one, an ohmmeter check between the "dead" contact of the fuse holder (no fuse fitted)and chassis ground may show a dead short. Tyring each of the connectors in the boot in a similar manner may isolate one particular wire. Then you know what colour wire you are looking for.
Then it's just a matter of tracing the wiring loom back (I think it runs under the floor coverings from memory?), until you find the damage.
A wiring diagram won't really help, lights are always wired in a simple circuit. Somewhere the wire from the switch will split to go to the other light(s), and a short could be in the second or other wire.
I have seen shorts occur even IN light bulbs... so if the fuse doesn't blow after removing the bulbs, check each one before replacing!
