- Q: both these components stopped working suddenly on my automatic 2001 toyota Rav4 today. I have had no prior problems until this morning, now both arent registering anything at all. Any ideas what the problem might be, and how much its going to set me back financially to fix it?
- if the gages read nothing i would start by checking fuses.
- Q: Hey all, I just bought a 1981 Subaru GL on Saturday--my first car, yay!Anyways the guy I bought it from said that the headlight fuse ocasionally blows out. Yep, its done it twice since I've had it.The first time I was driving and charging my phone in the cigarette lighter (maybe it can't handle everything at once?). Second time was two hours ago I went to start the car and the lights wouldn't come on.What's the underlying issue here? Fuses are cheap and easy to find but id rather fix it for good than having to buy a new set of fuses every couple if weeks.
- Check your wiring harness. It can be shorting out if there is contact between two bare wires (rat damage) or a wire that is not grounded properly. Make sure nothing is stripped or bare, you should never be able to see through the plastic on wires. Make sure your battery is not corroded and grounded properly. Test light your harness to make sure the hots are hot and the nots are not. There is a lot of stuff on forums for wiring diagrams and such to make sure that no one pieced it together wrong or cut/spliced into something they shouldn't have. If your Lights are spliced with a higher voltage component the wires will get hotter than they were designed for and that will cause a fuse to burn out. Hope that helps. Follow the wires from the back of your headlight all the way to the firewall and make sure connection to battery is still good (will will likely have to pry apart that black slinky looking wire cover to make sure it's all good under the hood). Make sure to check for signs of pests!
- Q: a motor, a generator, a battery, or a fuse?
- Generator: mechanical to electrical Motor: electrical to mechanical Battery: chemical to electrical Fuse: electrical to thermal, so that it melts to protect other components
- Q: A friend of mine has left town for a week, so another friend and I decided to install air horns in his car as a Christmas present/practical joke. We wired the horns to his existing horn button and it seemed to have worked for a short time. Then it stopped. We assume the problem is a blown fuse and we're going back in to check/work on it more soon. My question is what should be done after replacing the fuse to assure no further failure? Obviously the horns are drawing too much power, but will any electrical components solve the issue? Possibly a higher gauge wire?
- Wire a relay into the circuit. A relay is basically a switch that is turned on by an electric current. So you wire the relay into the circuit just like you have the horn wired now, and then run a wire from the battery to the secondary side of the relay and from the relay to the horn.
- Q: I turned the key once for the electrical components and it worked for a split second then it went dead. Then I tried to jump start it and nothing happened, no clicking or anything. just dead. Then, when I unhooked the jumper cables, there were sparks from the jumper cables which would indicate that the battery isn't dead.
- If the jumper cables were still hooked up to the other vehicle, then that is why you got sparks between the two cables. How long did you leave the cables hooked up to your vehicle while the other one was still running? Hook the cables up to a good battery and then to the bad battery. Let it charge for a few minutes and go back and give it another try. If you still don't get anything, then you may have a cable loose somewhere, like between your battery and starter. Could be a solenoid or a relay also.
- Q: Hi everyone, i hope you can help me out but i have a 92 grand am with a OHC quad 4 engine, 179407mi. I am trying to start it up and the engine turns good but not cracking up, Put new spark plugs and reconnect the ignition components back up, except there is a red wire tip clamp that needs to be connected back up, (WHICH IT WAS ALREADY OFF BEFORE TAKING COVER TOP OFF) i look and look and look for find where is goes and cant, also when you turn the key to the ON position i don't hear the fuel pump hums like it usually does, I ran outta gas a few times and wonder did the fuel pump shut off? or going bad? or just a relay/fuse? which i hoping that it is a relay/fuse, so please anyone can you tell where i can find the fuse/relay? and what does it looks like? and any more tips i need to know?
- Sounds like the fuel pump fuse.try looking under the dash or on the side of the dash when you open the door.if it isn't there it will be under the hood.I would reccomend you go to your local autozone and purchase a $15 book on your car!! not only will it help you find those pesky relays and fuses.but it will also have a wiring diagram to show you where that disconnected wire goes.but don't fret if you can't find that because sometimes car manufacturers use wiring harnesses for different cars and option packages and that wire may not be used for your vehicle.although given it's location my guess isthat it goes somewhere.Buy a book if you are going to be doing your own work on the car.it is a invaluable investment!!!!!!!!!
- Q: I am trying to install a additional parts to my car. when i remove the bare PCB with lcd from the head unit. i accidentally grounded the circuit board to the Metal plate, it create a little spark. now the LCD doesn't work. my question are1. is the circuit board fried?2. could it be just a blown fuse?3. after ground the board, could it be just burn resistor?
- Fried! Sorry.
- Q: connectors on the backglass. no damage to the defroster grid. is there an inline fuse in the lift gate that i might have missed, or could the switch be bad and still light up?
- You won't get power to grid because it goes to ground. You'll have to unplug it at the connector near the grid and read the grid with an ohm meter. If it's open, you may be able to see where its damaged. Sometimes when you clean or scrape frost from the inside glass, or maybe when you loaded something the grid got damaged. . The grid can be damaged pretty easy. Your favorite auto supply will have a repair kit for your defroster grid. You won't see wires go from the body of the car to the components of the tail gate.There is a pressure connector that makes this connection. On one side there will be a plate with dividers on it. On the other side you'll see the pins that are spring loaded. They line up and touch each other when the tail gate is closed. They stick out about 1/4 inch. You can clean this plate with a pencil eraser. Do the same with the pins. Use a little di electric grease on them. This is where the tailgate components are grounded. These components are activated by switching the ground. That's why you won't read power at the component.
- Q: Any schematics would be very helpful, or an exact fuse location. I know it should be in the panel, but I do not have an owners manual. No power is getting to the fuel pump, but is getting to the sending unit. Thanks fo your help.
- It is in the fuse box by the drivers left foot. you have to pull the fuse panel off and then the panel that it attaches to. In my car it was the black relay in the front of the fuse box. It isn't marked on the inside of the fuse panel.
- 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.
