If your headlights flicker or dim while under a load such as large amplifiers or blinkers then you need to track your grounds. Battery to Block then from Block to Chassis replace with larger gage wire or add more grounds.
Which ground wires? Most of them ground either to the chassis or the body. Any fastener which you can get a good ground with will suffice.
Most likely through the bearings. Since the column shaft is in constant contact with the bearings, which are in constant contact with the column body which happens to be bolted to the chassis, the center of the column has no problem finding a good ground.
I take it to my mechanic and say, "it's broken. Can you fix it"?
I had the same problem on my '95. First check the fuses under the hood. Second, check the switch on the steering column (google "how to check pathfinder headlight switch). Third. Ensure the Black wire from the headlight bulb connector is a solid ground (mine wasn't...) and I had to cut the wire and make a new ground connection. Apparently the ground goes to the chassis, and in my case, that chassis point was rusty... good luck..
put lemon in your hair and go outside with it on for a good hour or 2
I might start by checking the ground wire of the taillight assembly. Make sure there isn't any rust that is preventing a good electrical connection to the chassis ground.
try checking you ground for a good connection. may try to ground radio to chassis. you can also buy a noise filter at an audio store that will take it out.
Yes you can if the battery is the problem. connect the red on car with good battery to the positive ( + ) terminal, then the red on the dead battery, connect the black to the negative ( - ) on the good battery and the black to a good chassis ground( exposed metal in engine bay ) a good spot is the strut mount bolt.
Check the ground wire between the socket and the vehicle chassis and make sure that the connection is good.
Well it engine isn't that good but my mom has one and loves it:)
Sounds like you may have a bad ground. If you have changed the original battery cable ends, the chassie ground wire may not be attached or may have a bad connection. there should be a wire that attachs to the negative cable and goes to the chassis. sometimes they are bolted to the fender well. Another thing you may want to check is the ground wire from the engine block to the battery or chassis.
Check for a chassis ground behind the carpet under the tail lights(some cars have a threaded stud there). If not, use a self tamping screw and drill in to the unibody/frame in a location out of the way(like near the seats or near the bumper), so cargo can't damage the connection.
