Question about 1993 Chevrolet Beretta

1 Answer

I had a small fire caused by what I think is a loose ground wire that was not attached to my amp anymore. It burnt the driver side of the back seat and i assume any wiring in that area. The car will not start and i do not hear the fuel pump turning on. I am about to gut the interior of the car to survey the extent of the damage. Any ideas of what wiring harnesses or wires that would be running from inside the care to the trunk in that area that would cause the fuel pump issue? Could it be that the faulty ground that started the fire is keeping it from getting power? I used a ground in the trunk on the driver side wall of the trunk. Any ideas would help me know what to look for as i remove the seats and interior carpet.-Tony Fort Wayne, IN

Amps draw a lot of current so it should have been fused to avoid this problem, but since it happened, chances are the fire damaged the harness and burned through wires. When you take it apart you will see the area of damage. and you will have to repair or replace the damaged sections. the wire that caused the fire was probably the positive feed to the amp, somewhere it grounded out and since it was not properly fused it got very hot and damaged a harness that was close by or touching the feed wire.

    It was fused in two different spots. I replaced all of the wires i saw matches to yet three thicker gauge wires remain. a white one a red one and a black one that has multiple smaller like 20 gauge wires in it. I still have no power to the fuel pump and cannot find anywhere to splice the aforementioned 3 wires. The relay has all of the wires attached and i do not see any other holes in the floor to go to the pump.

    did the fuses blow? Have you checked all the fuses in the cars' power distribution box, and try swapping out the relay for the fuel pump with another relay (like ABS, or horn relay)? just a thought, but when you pull the rear seat out, pull the carpet above the fuel tank and see if there is a plate you can remove to access the fuel pump You'd then be able to trace the wiring from the connector/harness into the interior and maybe find the break. if there is no inspection plate, you might end up dropping the tank, not an easy job especially if it is full of gas. the burned wire needs to be located and puling apart the rear of the interior will find it.

    There was a 20 amp fuse in the engine compartment on the top of the firewall near the relay. It wasnt hard to find once i starting following the wire that left the relay but it was not labeled anywhere. It merely had 2 wires going in and thats it. it was a pain to get it out as it had a push in plastic type thing holding it to the bracket so i just broke the thing off and opened it up. There it was the solution to my problems. Replaced it and it started right up

2002 GET Yukon XL. Drivers side fog light works. Other side does not. Replaced bulb and the connector. Still not working. What should I look for


If you can read an electrical schematic of your car, get one and map the direction/location of the wire harness that sends electricity to your dead fog lamp. Check the wires for current until you find current. then check the wiring between the found current spot and the fog lamp for bends/breaks or any other problems that would cause it to not carry the electricity to the lamp....if you can't read a schematic....just uncover and follow the wires back to your fuse box...carefully....not causing any problems along the way.....removing the wire harness covering and inspecting the wires...physically...by feel or by sight....looking and feeling for a broken connection or burnt wire....use an amp meter to probe the electrical current if you know how to use one......somewhere within the wire run there will be your problem....the hard part is finding it....or if you are electrically inclined....rewire the whole run back to the fuse box....and even back to the switch on your dash.....it could be the switch in your dash is faulty and doesn't make a good connection to the one bad side when switched on....so use the amp meter to find where the electricity stops in the wiring....this will tell you approximately where the problem is....use the sharp pointed probe ends to check the wire conductivity inside the plastic wire wrapping, and make sure to have a good ground spot for the other probe end or other end with a ground clamp to attach to. I like the newer amp meters that open by depressing a thumb trigger and close around the wire to be checked, reading the current through the plastic coating just by being installed around the wire in question....no ground probe and no forcing a sharp end into a small wire stuff to deal with.....

turn the switch for the fog lamps on and start probing the entire system until you find the short or dis connection.... be careful when working on the cars electrical system....any work on wires in or around the area of your air bags should be done with a great deal of caution and preferably with the air bag system disabled. Don't be abusive to any other wires in the process...

Good luck and I hope I was of some help....

Where is the location of the power seat circuit breaker on a 2001 s10 blazer lt?


I think that more than likely wher eit draws the power in the fuse box the circuit feed to the fuse is burnt out ,this is often a strip on the back of the fuse box that runs across the frrd to the fuses so check for a feed in the fuse box on the fuse for the power seat

Second wire in engine compartment fuse box melted? where does wire go?


secondary ground wire fried!!? this tells me that your main ground did lose its contact somewhere.usually opposite the battery side. when this happens, and you try to say, start the car, all that amperage will follow any available ground it can find, usually through the actual wiring harness that covers the entire car. see, most vehicles have 2 ground cable setups..a main, and a secondary.. the main consists of the large cables as well as "ground straps" which look flat and are made of braided wire and run from the car body to the block and areas like that. now if these fail or loose connection, the only other source for grounding will be the loop i the harness which is not big enough to handle the amperage needed to run the starter motor when activated by the ignition key. now since yours burnt up, it must be replaced and all ground wires checked..also check for shorts in the system elsewhere, with a meter if necesary, you can also disconnect the battery entirely and connect a 6 amp battery charger directly to the cables(like charging the car without the battery) and if there is a short, the guage on the charger will peg over without fear of fire you will hear a buzzing sound where the short is (usually)..I have used this trick to find shorted blower heater motors or wiper motors on big trucks..if this ground wire is wrapped into the actual harness setup, you will need to replace it by cutting loose the old one, run a new wire into any part of the system thats not damaged, usually near the headlight fixtures, then run it back to the original starting point ,then its process of elimination as to what will work and what wont, remember, all circuits will function some with the charger attached instead of the battery, you will hear a buzzing or humming especially when checking the radio..good luck

The fire would be caused by the plug not fireing & hence not burning the fuel, the fuel would sit in the exhaust until ignited (lucky hasn't blown a muffler, The only way a piston could hit a plug is if it is the wrong plug (to deep) the conrod bearings are loose or extremly worn or the head has been ground to far. The dieseling probably caused by excess carbon from burning oil carboning up the cylinder this can cause melting of the plugs electrodes & burnt valves. I sugest 1st you take the plug to a mechanic or auto shop & have them tell you what they think based on the plug.

I've a 1996 Jeep Grand Cherokee Limited, both of the front power seats have stopped working, I suspect a short. I have a strong smell of burnt wire or varnish in the vehicle. Is there a master controller...


First of all: Ground your car till you fixed this problem! A short can cause a fire and, believe me you can't stop it!
Next: check the complete wiring for the seat first, then remove the seat and check wiring and switch inside. After that, check the motor(s). If there is no problem with the seat and the wiring in and to the seat, remove the dash board (you need to remove it complete! This will take a day, if you don't do this every day). Use a wiring diagram and check the wiring for a short or broken wire. The electrical system is not as simple as it was in the later 80' . Cars with ODB systems uses wires not only for a special system, like power seat. The same wire can be uses to activate other systems so it is not easy to find the electrical cramlin right at the point you think it have to be! Searching for a short can cost you days or, in some cases weeks.

Burnt ground wire on fuel pump


Burnt ground wire can be caused by loose ground fitting (not screwed in tight to the frame or body). Ground wire too small or ground wire connected to an anti-theft alarm system which use small wire, 10 gauge wire should be used on fuel pump ground.
If you have a lot of miles on your car, use a 5-40 synthetic oil, this will help oil comsumption.
