Are you connecting the power pack correctly. When jump starting the red power lead goes on the positive battery terminal (+ to + ) and the black lead goes on the engine (- to -) not the battery as this stops a power surge that can destroy the ECM. Blowing fuses indicates that you may be connecting black to red and this amounts to a dead short which will blow fuses.

SOURCE: 1987 camry blows 30 amp fusible link when ign turned to on positi

Something is drawing too much power and you will have to find out which it is. When the head job was done they may have gotten a wire pinched in the block or some thing. You would have to be quite mknowledgable in vehicle electronics to find it. I would suggest that you take it back to the shop or guy that done the head job for you to correct.

SOURCE: 2009 e250 keeps blowing 10 amp parking fuse then

Try putting a bigger amp fuse like 20. If it is still blowing it, there is a short somewhere in the circuit that is allowing excessive amps to through that circuit. Have a mech check that out.

SOURCE: keep blowing park fuse

The headlamp switch is at fault it seems. Best thing to do is to remove it and check for shorts in the wiring that connects to it before installing a new one. It could be the switch that just worn out but checking the wiring is best to do to safeguard your purchase. If you happen to instal a new one and the same thing happens again you can not return electrical parts for this reason. They been installed and no one else would want to buy it

SOURCE: I have a fuel pump fuse that keeps blowing. If I


The fuse blows when there is a short circuit in the system or an overload of current going to the conductor.

In the your case, the fuse blows up because of the fuel pump motor that is not working properly. The motor might have been stuck and still receiving current from the source, thus overheating your wire/cable and before everything else, blows your fuse as a safety precaution before big damage can happen.

Better check the fuel pump and the harness going to it!

Thanks for using Fixya!

SOURCE: ignition fuse keeps blowing out

Check your underdash wiring. At times wires can come lose and your ignition wire could be touching ground. Ignition wire in the explorer should be Pink and/or Pink/white. If you've had any aftermarket components installed in the vehicle, check all the connections to ensure nothing has come loose. Check for freyed wires or wires that could be cut by the metal under the dash. Ford uses almost razor-like metal in their dash boards so be cautious with your hands in there.

Sounds like you may have incorrectly connected the leads to start your vehicle and caused a surge of power through the electrical system. Most vehicles also have fuses in the engine bay so have a search and you may get lucky otherwise it maybe a task for a auto electrician

Jump-start Jaguar X-type? it's more complicated than you think.

Jump Start of Vehicle Battery


Turn off all electrical ancillary circuits such as radio, lights, indicators etc. If the reason for a flat battery is unknown the condition may be as a result of an electrical short circuit, so care must be taken during the Jump-start process and subsequent to connection to ascertain if this is the case. A short circuit or un-isolated ancillary load can cause arcing when the jump leads are connected, a small 'crackle' is normal but any spark or flash is an indication of a problem that should be rectified before attempting to Jump-Start the vehicle.

Jaguar do not recommended that the vehicle is jump started, and If at all possible it is preferable to replace the flat battery with a suitable fully charged unit rather than jump-start the car. However if it is done it should be carried out by suitably qualified personel. Garage services and services like AA and RAC homestart should be used whenever possible.

Obviously there are occasions when carrying out this proceedure yourself is the only practical way proceed.

If there is no option but to jump-start the discharged battery should be removed and recharged immediately after jump starting to avoid permanent damage.

High quality, heavy duty Jump leads must be used as the current consumption during starting is very high, and a voltage loss will be
exhibited though the jump leads, increasing current requirement.

Make sure that the Jump Start battery is of the same voltage as the vehicle, and suitable to provide the required starting current.


Connect the jump leads in the following sequence.
Connect Positive Jump Lead to Jump Start battery positive terminal.
Connect Positive Jump Lead to Vehicle battery positive terminal.
Connect Negative Jump Lead to Jump Start battery negative terminal.
Connect Negative Jump Lead to a suitable vehicle ground point at least, 300 mm (12 in) from the battery terminal e.g. engine lifting bracket, do not do not connect directly to the vehicle battery terminal.

Start the vehicle and rev to 2000 rpm, then allow tickover for 5-10 minutes.

Do not attempt continued repeated starting of the vehicle, this will cause heat build up at the terminals and though the jump leads degrading the leads performance and adding to voltage loss.

Allow 3-4 minutes recovery time for the leads and Jump Start battery between attempts to start.

Before disconnecting the jump leads, switch on the heated rear screen, to reduce the alternator voltage peak when the leads are removed, as this can damage electronic equipment.

Disconnect the jump leads in the reverse order to the connecting sequence taking great care not to short the ends of the leads.

Do not rely on the alternator to restore a discharged battery.
Ensure that the battery is recharged or replaced with a fully recharged unit
as soon as possible.

Following Jump-starting of a compleately discharged battery, you may need to carry out a Green ECM drive Cycle, this will allow the powertrain control module to 're-learn' idle values, and most likely need to re-enter your radio code, details of these can be found at.

93 miata, only the headlights work. it keeps blowing the btn fuse as soon as i put it in. are the diodes bad on the alternator?

Hi Lee and Chuck, Seems you have a serious short circuit in your vehicle. The fact that when the vehicle stands it will need to be jump started would seem to confirm the same. The power seems to be draining somewhere! The fuses which blow will give an indication of which circuit is shorting. If your brother wired in a music system or radio, disconnect it and then see if the fuses still blow? If they stay fine you know where to start. The music system is connected to the lights for night illumination of the controls. It may be that the earth connection has been mixed up with a power cable? If the vehicle runs fine during the day and does not give problems when restarting, it would be doubtful that there is damage to the alternator. You can check it fairly easily by connecting a test meter to each of the terminals. Start the vehicle and if while cranking the voltage drops below 8 volts, get the battery replaced. If it remains at about ten during starting that's fine. Measure the battery voltage before starting and confirm 12 volts. Once started the voltage should be at about 13 volts if the alternator is charging and when the horn is pressed and the wipers turned on together with the heated window, the voltage should climb to about 13 and a half volts. If the voltage remains unchanged or drops the alternator is damaged. Usually the head lights would be turned on to carry out this simple test but as the fuses blow you can do that when you've found the short circuit. Good luck and best regards John

As reported before, there is no power in interior,vehicle will not start.,battery is fully charged. there is 12 volts at battery , and at starter relays bottom terminai,no voltage at top terminal....

check for corrosion on the large positive wire that leads to the starter. allthough you have 12 volts, but corrosion cant handle amperage. or it may be possible that you just need a new starter, you can remove the starter, and apply a seperate power source like a jump pack or seperate battery to verify that the starter is ok

Check your underhood fuseblock fuses.chances are the large 60 amp fuse for the power steering blew out.In the future I would stay away from jump starting and use a booster pack as these vehicles do not like voltage spikes.I have seen it cause module problems.

My 15 amp dome fuse keeps blowing. Car is a toyota echo 2003. The battery is flat and I have been trying to start it with jumper leads but it will not fire and the 15amp fuse is the only thing i can see...

Remove the battery from the car and charge it up first and then re install it.Some newer vehicles will disable the fuel pump if the battery voltage is low,even if it is jump started ,as it activates the anti theft system.
