- Q: I have a toyota corolla 2000. Fuse of my car blown up immediately within five minutes after replacing it with a new one. The fuse is of 15 ampere and its related to EFI or F-HTR. Please help me to troubleshoot the problem to the component level.Thanks,
- You turned your big huge powerful sound system on and because you for some reason used that fused circuit as your power source? or you got real problems. Never put a higher amperage fuse in than whats recommended that's a way to do even more damage.
- Q: I just asked a question about my 2006 trailblazer with 48,000 miles. The service engine light does not come on when I turn the key over, neither does the seat belt light. What worries me is that I see a scuff in the dash where the screw is to remove the dash. The car hasn't given me trouble and I took it to chevrolet to have a work up done on it, and it was hooked up to a computer and no warnings came up, but WHY would that light not work? I am guessing somebody has probably tampered with it, and trying to screw me over, but its actually been a marvelous car so far. Chevrolet told me that the light is tamper proof, but I don't see how. Couldn't they just pull it out, or color it with a marker or something? I hate having the wool pulled over my eyes and it pisses me off to think someone would do that.
- I suspect you're on the right track - it sounds as though a prior owner has removed the bulb.
- Q: I was plugging my tom tom into my ciggarette lighter to charge and a penny fell into the lighter hole. Im driving so I grab a pen to get it out and the pen bursts leaking ink everywhere. I then notice my car radio just shuts off. I try to get the ink out as best as possible and I plugged up several chargers, but none come on and nor will my radio. Did I really screw something up I can't live without GPS or Tunes. Real help only pleaseI'm gonna go to Auto Zone tomorrow to test fuses, but any help still appreciated.
- There's no need to look smart when you take it to the pro's. That's what they're there for. Not everyone is car savvy, you just have to be savvy enough not to get ripped off. Take it to a mechanic right away, most problems only get worse if you keep driving with them. If he can't explain it to you to your satisfaction, take it to a second mechanic for another opinion.
- Q: I currentlyinstalled a new batteryon my Navigator. When battery was installed the radio was not working anymore and completely dead. What is wrong??
- Yep check your fuse. Electrical components age together, when you replace your battery, your adding 100% pure juice instead of the 90% your components aged at. Check your Owners Manuel for location of your fuse box, then check your fuses for burned out fuses
- Q: I just purchased an corsair 750W power supply, and the input is mentioned as 90-264V 10A, Now on the plug that connects to wall socket to power it says 13A 250V (UK Pin) Now i am using it in asia, using an simple adapter but inorder to plug other things like speakers and screen i am buying an surge protector (spike guard).Now at what Amp shall i buy spike guard ? Rated 15A or 10A - As this is what available in my country. PS: The fuse power on the inbuilt fuse on the power plug is 13A. Also inform if i buy a 15A Spike guard and the usage say is only 10A is their a con like, smoking the pc components incase of sum overcurrent?
- It is always ok if you have more Amps then needed. If you go under of what the devices needs then it will simply burn.
- Q: I have an old Lennox unit. The AC still runs fine. Heater quit on me back in March. not sure if the elements or what. winter coming soon and need to get this up and running again
- Check the fuse's first. If they are good and the blower fan motor is running, the problem is probably either the heating elements or a disc limit is bad. The best way to check these components is ohm them out with a multi-meter. If you have not worked with electricity before I would call a qualified service tech to check on this problem as you are working with high voltage and it can be very dangerous. When you find which part is bad you can call a certified Lennox dealer (just look in the phone book) and give them the model number of the unit. Lennox is very good about keeping parts in stock even on older units.
- Q: Hi , I want to know what are the various components which needs to be fitted for putting AC in my non-AC Maruti 800? I want to make sure the mechanic doesn't take me for a ride.
- Wow. That's a lot of work and parts. Start with the compressor, which is expensive for an average car, plus condenser, high and low pressure valves, hoses, lines, sensors, expansion valve, and the relay system which will need to be wired into your existing fuse system, which may have to be replaced as well. He'll have to use new parts because old parts from junk cars will have dry rot and corrosion, plus it's not good for AC systems to sit for long periods with no pressure or oil inside.
- Q: 2003 dodge grand caravan the parking lights wont come on and i can find the fuse! i looked at the fuse box in the engine compartment and all the fuses look good! is there another box ? please help. ps my headlights work and so are the dash lights
- you probably might need to change your light bulbs if they are burnt out or one of the relays is short.
- 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 was just wondering what happens when an electrical component or circuit becomes 'shot' as we term it. Now I am studying engineering, and my field has delved slightly into electricity, so I understand electricity to a point. But anyone out their with a good understanding of electricity, what exactly goes wrong? Thanks.
- Many things can occur to make a piece of equipment malfunction (you may use the term shot, but others don't). Semiconductors can sometimes grow whiskers, tiny metal fingers that can cause shorts. Semiconductors subjected to thermal cycles can die due to cracks in the die, or leads breaking. You can have bad solder connections on PC boards or connectors that eventually fail. Connectors can wear out from repeated use, or the wires can break in cables. Poorly designed electronics can die early due to voltage or thermal stress, exceeding the ratings of the components. The most common failure mode is around connectors and cables. If I think of the failed electronic devices I have seen in the last 20 years, I can list a PC with a bad memory connector, a PC with a broken key on the keyboards, An electric heater not working on HI, with a faulty overload trip, A scanner with a bad cell. A CRT type TV where the screen brightness slowly faded till it was not usable. And that's about all, the rest are due to obsolescence. .
