Q: I remove the negative battery wire, put my multimeter inline with the battery and said wire, and place it on DCV 20 and see if there is a draw with all the lights and components turned off. Then start removing fuses until the draw drops?Additional Details98 ford mustang v6 3.8L manual trans
I would use the meter in current mode, not voltage. Look for the DCA range. You might have to switch the positive lead to another port for testing current depending on the range. Like you said, hook the meter up in series with a battery terminal and start pulling fuses until the current draw suddenly drops. Then you know which circuit to investigate.
Q: I have an old 1998 dodge stratus and it keeps blowing the ignition fuel starter fuse(20A). I replace it 4 times and they failed. Can someone tell me what's going on and I can get over this?
The ignition fuel and starter are all on the same circuit?? Seems odd, but possible I guess. Your going to have to get an amperage draw test done on the individual components of the system and see which one is drawing enough amps to melt the fuse. Could be the components, the wiring (not likely) or the control module (rare). Also could be a short to ground or short to power. Sounds confusing but I bet it's faulty internal starter windings causing the problem. Have the starter removed and professionally tested by a reputable auto electric shop not a parts guy that thinks he's a mechanic. Also if it's a manual transmission car try parking it on hills and roll starting it to verify the problem if this is possible.
Q: I have 1999 Honda Accord. Recently, the buttons on the Climate control panel stopped working. The round knobs controlling air flow into the car and the temperature are fine. It is just that I cannot control where air gets directed via those buttons. At the same time, the clock is not illuminated (the clock is fine). Would like to find out if there is a fuse or an electrical component controlling both (control panel and the clock light) has gone bad? if yes, where can I find it? thanksrajesh
hard situation. research at bing and yahoo. that will could actually help!
Q: Causes 3 amps of current to flow to your stereo? Why is this a good thing?
The sudden surge of 3 amps causes the fuse to burn out breaking the circuit. This stops the flow of electrons (current). Breaking the circuit protects the electronic components of the stereo by preventing too large of a current from passing through them.
Q: Hi everybody, I tried asking somebody to check the engine light on my car, they accidentally jumped the wrong cable which seems to have stopped my sony car stereo from working now. I checked the radio fuse and fuse behind the stereo and they all look fine. I am still able to eject and insert a CD into the system so that means that power is getting to it right? Is there a reason why the head unit doesn't come on?also Is it possible to fry your cars wiring with this mistake? But isn't that what the fuses are for? Is it just my head unit?thanks in advance!
No, fuses do not protect against reversed polarity. They are designed to protect from shorted electrical supply wiring and overloads (excessive current). Reversing the DC polarity to many devices will spell sudden death. Depending on how long the condition existed, there could have been a really huge buildup of heat which has damaged power supply components. One reason that reverse polarity is used with DC welding equipment is that normal polarity puts more heat into the workpiece, whereas reversed polarity puts the heat into the welding electrode.

Q: I have a pontiac Grand Prix GTP, its 2000 the under hood is clean but not clean enouch, Should i just go to a car wash and use pressure water on the engine components? how does one clean these wiers and stuff the dust seems to be every where, are there any pros who do it for you? is yes how much taht cost?Pls helpThank you
After you've degreesed and power sprayed it, buy a couple of rolls of paper towels and some household cleaner. Spend an hour wiping the components and connectors by hand with the paper towels. While your'e in there get the exess water out of there. Use can of brake cleaner on those hard to reach spots. It's worth the hour or so of effort for a nice clean engine compartment, and a must do if your prepapring to sell the vehicle - it says I cared for this vehicle to any used car buyer.
Q: I have a Sony R2400 stereo system that apparently overheated during hours of continuous use. Now, when I turn it on the only thing that comes on is the red light indicating which playback method is selected (tape, cd, etc.). Does anyone know what component would likely be the damaged one causing this? I am an engineering student, so I am willing to make an attempt at a repair if I can figure out what is wrong. Thanks.
the speaker wires may be corroded,too long,or shorted when pos neg are inserted into speaker wire clips,the net needs to allow a refined search so one can find the device itself,maybe the patent prohibits repair people from showing pics schematics,can you post/upload a pic of the thing? one of front,rear,speakers,and aux components?
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
Q: Hi I never used the cigarette lighter in my Lexus es300 1993. . i recently bought a car cell phone charger and it doesn't work. I pushed in the cigarette lighter and it did not heat up. I replaced the fuse and it doesn't work.any suggestions will helpthanks so much,ALex, nyc
there should be another fuse box next to the motor under hood on right side i think,check them i think your supposed to unhook your battery for this but you can call your local auto parts store and ask them they will be able to tell you
