Question:

How do i find a short in a car?

I Have an 01 mitsubishi galant GTZ and the right passenger side parking lights, (running lights) dont work. The dash lights also dont turn on. Now the fuse was blown and i replaced once i turned the lights on it would blow again. I asked around and i was told it was a short. How to fixx? Please help.

Answer:

There are a maze of wires that CAN be affected and need repair--YOU can't do much but get a professional to fix it properly!!
Check the wires from the assembly and work back from there. Good chance there is an exposed or frayed wire or wires. You may need to replace the entire light assembly itself.
Your dash light more likely works off the same fuse for the parking lights. maybe is not just the right side but the parking lights (running lights) over all? may be the car was involved in a accident on the right side and the wires may be touching some sharp metal or maybe on light bulb was replaced on the right side and it was installed wrongly (180* off?) I hope this info is helpful!
ok, first you need to pull the headlight out of the socket and visually inspect it for damage. and by damage i meanmelted contacts, frayed wires going into the back of the connector or faulty light bulb, look at the filament inside the bulb and check for sections that looked burned and/or fused together. if you don't find a problem there follow the wires from the plug back into the main harness, pay particular attention to the area about 10 inches from the plug. where most shorts are located is where the wires come in contact with the sheet metal on the car.i.e the fenders, bumper, and frame rails. also don't rule out the possibility that the problem is in the rear lights. especially if you have incandescent lights in the rear. more often than not i have seen internal shorts in incandescent light bulbs that make lighting systems do some REALLY weird things. if you have some natural mechanical inclinition and some electrical experience with a multimeter this problem shouldn't be that hard to locate. if not then i would suggest taking it to your mechanic, ground shorts can be a little tricky. good luck
Put a small 12 volt light bulb in place of the blown fuse. It will illuminate due to the short. Now go and start disconnecting circuits that the fuse powers. Your goal is to get that light to go out. The short can be inside of an electrical component, such as inside of the socket the parking light plugs into. So unplug the wiring harness from the parking lights one at a time and see if the light bulb goes out that you installed in place of the blown fuse. If it does go out, then the short is in the socket the parking light plugs into.
