With the car in the off position, remove the negative battery cable and use a multi-meter to test continuity between the positive battery terminal and the engine block. If there is continuity, you have a short.
Remove the positive battery connector and fit a 12 volt bulb in between the connector and the battery terminal. If you have a short,the bulb will glow. Now go to the fuse box and remove fuses one by one until the bulb goes off. -Now you know which area the short is in, and can pursue it by examining the components in the area by sight and by using a meter.
You can find a short in the electrical system by using an ohm meter ,,, check the wires between each other and earth ground . If the wires are shorted together or to ground the ohm meter will read a very low number indicating that there is no resistance ,,, If it is not shorted it will read a very high number or nothing at all. Example ,, with leads between wire blue and wire red read 20k ohm resistance (thus open ) wire black and wire grey read 1.2 ohm indicating that they are shorted together ...
The best way is too look under the hood at all places where a ring terminal and black wire are screwed into the body or frame area with self tapping screws. Clean these terminals and the metal underneath with 180 grit sandpaper or a wire brush, use a multimeter (voltmeter) to check for energy coming from the newly cleaned terminal rings to the cleaned metal area, and the from the terminal ring to the negative post of the battery it should read 12-14v even when returning to ground, if it is reading significantly less than that you may want to trace the wire to it's source. I recommend finding and cleaning all of the terminal rings and mounting points before giving up and sandpaper is very cheap.
To test for faulty wiring, ask a physican
It could be a number of problems. It could be the sensor is bad, it could indicate a fault with the alternator, faulty leads, faulty wiring... it depends on the situation.
We had the same problem in our '97. Check that your battery is fully charged and working properly, also check that the alt is working. If both of these are in working order it could be a faulty ground wire or the starter wire. Then, if those check out fine, I would start checking into your ignition switch and modular. I traced our issue backwards. If you know that the starter and the alt is good then it has to be in the electrical part of the car. Wiring or ignition. Hope this helps. If by chance it's something else please let me know. We finally found our problem in the ignition wiring. We had a bad wire going into the module. We have to push up on the wiring to get the starter to jump. Still a reliable car.
fault starter/cable, faulty solenoid, faulty wiring harness, or undercharged battery.
If light bulbs are burning out quickly the light fixture could be getting too much electricity due to faulty wiring. They could also burn out due to a loose wire or screwing the light bulb in too tight.
On a high energy ignition, possible problems include: Faulty keyswitch, faulty wiring or connectors, faulty pickup inside the distributor, faulty electrical condenser, if it has points (depends on the type of HEI) the points could be bad, faulty coil or faulty HEI control module. You will need to identify which component has failed.
Faulty bulbs, faulty switch, faulty wiring, disconnected ground.
Burnt out bulb, faulty wiring, failed computer
It could be a faulty gauge, a faulty sensor, or a wiring problem. What engine do you have in what year car?
Due to faulty wiring or excessive load.
Faulty wiring, faulty CECU.
The bulb could be burnt out, there could be a wiring problem, or the module could be faulty.
If your car doesn't have DRL's the switch is faulty or the wiring has a short in it to a power source..
It could be your remote that is faulty and while in motion it can activate. I had that problem. If not, you have a short somewhere in the wiring.
Faulty socket wiring problem Faulty flasher faulty switch
Blown bulbs. Blown fuse. Faulty wiring. Faulty relay. Faulty switch.
Yes.
Could be low on oil. Oil pump could be faulty, have to check the oil pressure with a real gauge. Or, just could be the wiring or a faulty pressure switch.
