Q:I changed all the bad fuses, then I changed the switch, then I tested the motor by hooking up a 12V battery pack, and it worked just fine up and down. What else could be the problem and how do I test it?Also, the window and the door lock mechanisms don't work on the passenger front door, even from the master control on the drivers side door.

it could only be a few things. Make sure the new fuses are the correct amperage second check the motor for the window last check the grounds make sure there all tight

Q:I want to add a circuit to my car to hardwire my gps and radar, and to run my rally lights.I have 10 gauge leads with a 30a fuse. I have 3 spst switches to run each. I have the appropraite fuses for each component.so to get to the point, i need to know how, if possible, to wire them in series so the voltage going to each is the same. This is my first time messing wiith electronics, and do i need to add any relays or capacitors?Thanks,Ben

A series circuit is one draw after another. If one doesn#x27;t work none work. Like Xmas tree lights if one goes out the whole string is out. I think you want parallel circuit. One hot lead and separate switches controlling each draw. It would be better to have individual fuses for each accessory. Do have 30 amp fuse on the main hot lead.

Q:I have a 2000 Chevy Cavalier 2.2L Automatic. Tried starting it and nothing works. What DOES WORK are the headlights, horn, door chime, brake lights, tail lights, hazards, and the interior lights. No idiot lights, radio, heater/fan, and doesn't turn over. Battery is charged. I also put a screw driver to the posts of the starter and it sparked, so juice is going to the starter. I know that it is something electrical. What puzzles me is that not even a idiot light comes on, even when I turn on the headlights, the dash lights turns on as well and that didn't come on. Does anyone know what I should look for or check? Has anyone heard of a Relay that goes bad where GM had a recall once? No answer is a stupid answer unless you tell me to check my antifreeze. Thanks!

Ignition switch may be bad. The Radio, Idiot Lights, Heater/fan only work with the ignition switch on. All the other lights, horn, door chime, etc work weather the key is on or not.

Q:I was wondering if anybody could tell me how to find a short circuit in my car because it is draining my battery. The car has all electrical components brand new such as the alternator, starter, battery, voltage regulator and relay. The car is not blowing any fuses but drains the battery overnight. Can anybody tell me how to test for a short circuit? Thanks to everybody that helps.

Use a test light to determine which circut is drawing power. Remove one of the battery terminals from the battery and connect the test light between the cable and tthe battery post. If there is a parasitic load the light should shine reasonably brightly. Remove fuses one at a time until the light goes out. Then you will have your short narrowed down signifigantly.

Q:i am working on a 200 mbz ml320 suv. both power seats will not work. I checked the fuses and they are good. I checked the grounds, and they are good. I even took the seat out of the car and tested itand its good. Just wanted to know if it could be a relay and something else i am not thinking of.thanks everyone.

same thing with my ml320 take the connectors apart and clean them with a little sand paper 100 grit

Q:I have a 30amp fuse that operates my door locks and power seats. I carry around a box of them because sometimes the fuse will last a couple of weeks, or days or hours. Any ideas of an easy fix?

Either you have an intermittent short to ground in the wiring or something on the circuit (motor, for example) is adding resistance and subsequently pulling excessive current because it is binding/starting to fail etc. and causing the circuit to overload and the fuse to pop. Is there anything else on the circuit that you know of? Do the power seats move smoothly and consistently on the tracks? Some cars have several motors that control the power seats so it can get complicated if one of them is the culprit. If it is not in the wiring and a component is causing it it sometimes it is easier to wait for the problematic component to take a sh*t and then just replace it. That's about the best that I can say over a computer. Good luck!

Q:i already had a 600w rms mono amp for my bass and a 1.0 Farad Digital Car Audio Capacitor, and it was fine for a year , a few week ago i install a 200w rms American pro amp to run my door speaker and it happen every morning i had to jump my truck, i unplug that new amp for a week and everything went back to normal during that week i took truck to dealer for a 250 point inspection everything was fine ,i saw that my battery was a cheap factory battery so i got a optima battery i rewire everything 0 gauge front to back and 4 gauge on back to wire both amp and cap.after all my truck die agan , had to jump this morning

It may seem obvious to you already, but there's an issue with your American pro amp. It sounds like the amp is staying on all the time. Make sure the REM input only has +12volt power when the key is turned. The remote lead from the HU is supposed to switch the amplifier on, but if you've got a stock radio you might want to tap a fuse in your fuse box to get switched power. If it's turning off like it's supposed to, it has an internal fault making it a constant drain on your battery.

Q:I have a lenovo model 0768 and I want to know what parts I should buy for it to make it a gaming laptop. I have 700 dollars to spend on it and it still has the original parts in it. Thanks for answering if you answer.

you cant make a non gaming laptop into a gaming laptop. you can do this with desktops only laptop's major components are fused to the motherboard and are not replaceable/upgradable so your only choice is to buy a new higher powered laptop

Q:2.8 manual trans blows ecm b fuse in the under dash fuse box. Changed relays(2), fuel pump and ecm. It might be the fuel pump primer but I don't know where it is located.When I bypass the relay the fuel pump runs but when I try to start the engine while it's bypassed the bypass wire from the positive battery post gets red hot. The engine used to start while wired in this fashion when the fuse would fail. Now the fuse fails all the time.

You have a direct short in the ECM B circuit. When you bypass the fuse you destroy the harness, fuses are to protect the harness and the components they are connected to. They protect the ECM. The B circuit usually is the power circuit for the fuel pump, through the relay. Check the harness for continuity from the relay connector to ground from the fuel pump power supply wire I think it's tan/wht. If there is you have a short and you will need to pinpoint where. but you have probably already melted the harness together. Good luck. It might have been cheaper to hire a professional mechanic shop.

Q:I checked the cooling fan fuse underneath the hood but it is fine, i think that is for the radiator.There is 20 fuses in the hood fuse box. In the interior fuse box there is 25 fuses but my owners manual does not state any mention of an a/c fuse. What # is it?Where is the fuse for the air conditioner?2002 honda civic sedan.

both fuse boxes will have a/c components, and not just fuses. there are also relays
