Q: I have a 1988 Jeep Comanche Sportruck and all of the gas, speed, etc gauges are not working. The lights that lit up the gauges used to work before I recharged my battery, since the jeep was left sitting for a couple months. But ever since I had the truck none of the speed, gas, and all the rest of the gauges have been reading/ working anything at all. What could the problem be and how could I fix this myself before having to go to a repair shop? Thank you for your help I've had this problem for so long and it's just time for me to fix this.: Check fuses, if not a fuse, replace the dashboard gauge circuit board. DISCUSSION: Check the simplest and cheapest things first (fuses). If it is not a fuse problem, the easiest (and possibly the cheapest) step is to replace the dashboard gauges with parts from a junk yard. You might have blown the voltage regulator on the dash board (not the voltage regulator associated with the alternator). The difficulty of getting out the old dashboard gauges, and replacing a single component is slightly more than the difficulty of getting out the old dashboard gauges and replacing the who dashboard gauge circuit board, gauges and all. You might have also blown some gauges, so even if you fix one component, you might have to go back in to fix more. It is better to recharge the battery when it is disconnected from the car (to avoid the possibility of blowing out sensitive electronics such as dash boards).

Q: i was taking off my car battery and when i touched the screw with the pilers, sparks flew and all the electricity in the car is not working now! what did i do?: You have popped some fuses, or perhaps burned up some components, like voltage regulator or relays, or worse, burned some wires. You have generated some business with a car repair shop.

Q: I dont really know much about car electrical systems, im only 17 and im trying to learn. I only know a little about wiring (like pos and neg from physics class last year) I want to install 2 neon tubes, one underneath the driver and passenger dash. The fuse box is to the left of the passengers foot (2008 vue) I opened it up and all i see is a bunch of little plastic squares for each component (for example, power windows, On Star, radio etc) There are also 2 that say spare which i think i could hook up to, or even the power seats fuse because i dont have that so it wouldnt have anything right? What are the next steps? I dont understand where you actually hook in the wires??Thanks!!: your car dont have power seats but if you look under ye seats you should be able to find the conectors for the power seats as the car is wired an then the seats are put in at the factory so if its got power seats they plug them in if not then they just leave the plug or tuk it under the carpet,you will have to find out which is live and so on and make sure u use the right amp fuse,but it should be pretty easy to do.the other way is buy some think at pound land with a cigarette lighter connector an wire it up that way just hide the wire under ye carpet then plug them in an when u get sik ov them pull it out

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 have honda accord 1995lx.i was asked to change the fuse cause the window was not shutting down .I changed it and it worked.but the speedometer was down.the next day,my ignition switch broke down .i think there might be some electric short which damaged the ignition switch.ii replaced iti and it works now.i was wondering whether the electric short can damange the parts or not?will appreciate the response.thanks.: Yes an electrical short can cause damage to other parts. A short produces a power surge on the line and can burn out other parts in the same circuit. Unfortunately you may have to unwrap your wire bundles to find it. Or it could be as simple as having a fuse that is shorting.

Q: i have checked the fuses. they are good. can i just replace the bulbs or does the whole component need to be replaced?: you don,t have to replace the whole lens, just the bulbs.

Q: I was told to replace the distributor and check the fuses. Also to check the wiring from the distributor to the alrenator. Where is all this stuff at and how do I check it The car just stopped and sounds like it is going to start but won't. Thanks: Best to take it to Mechanic or garage dealing with Toyotas and Japanese autombiles but we use to have a 1993 Toyota Camry LE (kept it like 12 years and had 211,000 miles when my wife and her sisters upgraded to SUVs as she now drives 2005 Toyota Highlander 6 cylinder AWD) and FYI replacing the distrbutor itself is very expensive part for just the electrical component itself plus labor and yes it does eventually go If you are planning to keep this 1993 Camry for some time in excess of 1 year, then my advice would be to pay extra for genuine Toyota distributor part rather than just OEM substitute bec I made this mistake before and the OEM part itself was $200 and died in month 13 after the parts warranty expired. I had previously replaced the distributor cap, 4 spark plugs and spark plug wires myself before with genuine Toyota parts but basically my mechanic confirmed my worse nightmare when the distributor failed again and had to be towed saying that there was no spark coming when he pulled the wire Again this can be costly repair so best to take to reputable garage as they will stand behind repairfor 90 days on labor and part 12 months. Hope the Above Info Helps!

Q: I have an 85 Mustang 5.0 convertible. one day, the stereo stopped working. At the same time, the fuse for the gas door, courtesy lamp and key warning buzzer blew (one fuse). If i try to put a fuse in, it just blows. Does anyone have an idea of where the short could possibly be? or can a component on that circuit fail and cause a short?: If the an aftermarket radio was installed, the wiring may of been done using just electircal tape, as some fly-by-night people do. Over time the wires may become loose, and hit a ground. Take the radio out and look to see.

Q: Any ideas what th FL5 50 amp fusable link is for, thanks in advance: Give the abs unit a slap with your palm.I had one of thes e with a stuck solenoid causing the unusual current flow What follows is not related to your problem but the info about FL5 follows:- If you have a Range Rover Classic or Discovery 1 that is getting up there in age and has had its share of use, not to mention exposure to western New York winters, you may soon find out how a fusible link works. Sometime in the 1992 Model Year, Land Rover introduced the fusible link as an added protection to the electrical systems in the Range Rover. This system also was used in the Discoverys. If you experience a number of sudden and simultaneous failures of various electrical systems and components, there is a good chance that you have blown one of these fusible links

Q: I have a 50cc scooter/ moped and for some reason none of the electrical components work: lights, signals, horn, fuel level dials on the dash, brake light, etc nothing electrical works.Yet for some reason the electric start still works? Why would this work and nothing else?: if you have fuses it might be that. if that isn't it, remember that all these accessories must all run from the same electrical point. trace one of those wires back toward the off/on switch until you find the problem.Have you checked the ground. some time the starter is a grounded alone. also turn one of these things on and check to see if you actually have power to it. its tough to answer this in a good way to get right to the exact problem partner.
