Q:A friend of mine has left town for a week, so another friend and I decided to install air horns in his car as a Christmas present/practical joke. We wired the horns to his existing horn button and it seemed to have worked for a short time. Then it stopped. We assume the problem is a blown fuse and we're going back in to check/work on it more soon. My question is what should be done after replacing the fuse to assure no further failure? Obviously the horns are drawing too much power, but will any electrical components solve the issue? Possibly a higher gauge wire?: Wire a relay into the circuit. A relay is basically a switch that is turned on by an electric current. So you wire the relay into the circuit just like you have the horn wired now, and then run a wire from the battery to the secondary side of the relay and from the relay to the horn.

Q:1993 Buick Roadmaster Estate Wagon: Did you check the fuse in the back of it? and have you checked all the good connections? Sometimes components just die especially cheap ones.

Q:i have got an 8 valve EFI k reg convertabile and i have only side lights working. i have no normal driving lights,no full beam and no ,rev counter,no fuel gage and no ignition lights.As soon as i put the ignition on the fuse 27 blows and the battary light comes on,can anybody out there help?: you obviosly have a short to ground somewhere

Q:i want use fuse 1A in my power supply circuit.i have never used a fuse before.so can anyone tell me how to use it and how should i place it in the circuit?: Fuse should be placed first in line of the hot legclosest to the power source.

Q:I am trying to keep my battery from dying overnight since i need a new door jamb switch b/c my interior lights will not go off.: disconnect the positive, the negative is used as a ground for most electrical components. By removing the negative and not the positive you are sending power to parts that have no ground!!! - PL

Q:2003 Ford Crown Victoria. Drove through some water last night and shortly after lost Power Steering, blower motor, A/C Heater. All of these things work fine after installing a single 15 amp fuse located in the car-by driver's feet. BUT then stops working after the fuse blows right away! What should I be looking for and where? Thanks: look for a mechanic in your phone book. you can seriously screw the pooch and your wallet if you try to fix this yourself. next time don't drive through water.

Q:I have checked every single fuse under the hood and under the steering wheel. Still no radio, clock, or dome lights.: Double check the fuses tor the dome light and cigar lighter, its easy to miss a bad fuse If you have a test light or DVOM (multi meter) use it to check both sides of the fuse for power, obviously an open in the fuse is going to cause one side of it to have power and not the other. You will need these tool to verify the fuse is getting power, check the condition of the fuse, and trace the power to the individual components on that circuit. For backyard mechanics, Harbor Freight has these tool for the $5-10 range that work great for occasional use. Good luck man! If you need any further help with open / short diagnosis just let me know.

Q:I have a 1989 5.0 l camaro that wont start. Ive replaced the starter battery and nothing. Ive also tried jumpstarting the car and still nothing. When i turn ob the ignition switch nothing happens. no sound or click. When i turn the switch on all other components start but the car just wont turn over. Its missing the crank fuse might it have to do something with it? Really need some help pls.: check the fuseable link for the starter. it could be burnt.

Q:I also here a thumping noise on the passenger side dash board when I turn the vehicle off what should I do: It sounds like the ac compressor clutch is bad. How to troubleshoot: Unplug the A/C compressor clutch wire and replace fuse and turn on A/C. If it does not blow, it is not anything in the wiring to the compressor. If it blows without the compressor plugged in you are going to have to check wiring and components from the compressor back.

Q:any suggestion to fix them would be appreciated.: check the fuses before you do anything I might just be a fuse. Refer to your manual to see which fuses control which electrical components. If it is broken, get a new one cost like 3 bucks. If not, you probably have to have someone look at it.
