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.: the light needs to be working because the computer system will not close loop until the circuit is complete. this is true no all the rest of the computer Components. now it might act like its running fine and it might run fine for a long time. but you will not get the emission to pass if you have to have it inspected. and one of the first thing the inspectors looks at.

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!: Check your fuses. Those that are under the hood and inside your car. If they are good then you'll need to test the power in your power distributor box to make sure the proper amount of electric charge is being sent to various fuses.

Q: I have checked the voltage at the disconnect and the breaker. They are fine. I have checked the display connection and that is okay. Where do I go from there? Any help would be appreciated. Thanks: there are fuses inside the spa pack that help PROTECT different components. if 1 or more are defective (BLOWN) then that can affect the top side controller. do you have a G.F.C.I receptacle on the spa pack? some times they trip also BUT they also protect the COMPONENTS of the spa system ! you need a QUALIFIED spa repair man to check for grounds in the spa system.

Q: I have a variac transformer rated at 7.5 amps but the fuse burned out. I want to increase the rating to 20 amps, can I do this by replacing the fuse with a 20 amp fuse?: Unfortunately not. If the current rating of a supply is 7.5amps, that's the max your gonna get. Putting a 20amp fuse in it will just possible cause the supply to burn up or possibly cause a fire. I definitely would not do this. If you were in a pinch and just want to test the supply, possibly you could, but again I wouldn't. Sorry

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: I have no idea what this component is or where to get one. It's from a sleep comfort bed pump and I need a replacement part. Here's a picture of it and the pump label.: I think it is a 1.6 amp fuse. Judging by the black streaks on the board, however, something else went wrong, and blew the fuse with a serious overcurrent. That is to say, just swapping the fuse is likely not to fix the unit; it will probably just blow again. Whatever blew the fuse is probably still wrong, unless you know what that was and have fixed it. You can probably just solder in a fuseholder in its place if you cannot find an exact replacement. One with wires at each end will probably be simplest. I suggest you ask the manufacturer how much for a new board. I am guessing that this is for a vinyl air bed. If so, if the mfgr wants too much for a new board, Coleman makes a very good inflator, included with their airbeds, but I think available separately for $15 or so, and you could probably kluge it into place, though you might need to remote the switch.

Q: I'm currently in the market to purchase my first washer and dryer set for my family of 4. We are looking to spend no more than $1,500 on a complete set. What are your recommendations? Obviously we are looking for longevity in the set. We do between 4-6 loads per week. Thanks for your help!: If you want longevity and value get a traditional style of washer and dryer rather than the so-called high efficiency models. Most HE washers are not made with water-safe metals; they turn into electrodes in water that slowly fuses components together, turning an appliance that used to be a 10-15 year investment into a 4-5 year expense. LG and Samsung in particular are notorious for this. High-end brands like Miele and SpeedQueen are great, but they also cost a small fortune. The top-loaders that don't have a traditional agitator are notorious for tearing clothes and leaving large mechanical grease stains/burns from how they agitate and spin clothing. For the best bang for your buck, get a traditional top-loading washer with an agitator tower in the middle and a traditional matching dryer. As tempting as it can be to buy those swanky gloss-black or red numbers at the hardware store, even the most expensive models will not last longer than a decade. Besides, ***no one will see them but you!*** I have a Whirlpool set at home, and they work great. My parents have Kenmore, and it's the same deal. Both sets are a decade old and still trucking along.

Q: I installed my brand new battery in backwards, it was late at night and i couldn't see what i connected. When the terminals connected, a green wire connected to the starter popped in smoke. I took my truck to a mechanic and they said i fried my computer and that i needed a new one.or a used one. IS this seriously what i didbecause this is a $500.00 F*** Up.: surprise! the computer is not fused on the ground side. when you power it from the ground side, the power does not just run in reverse, it burns out components. youll be lucky if you didnt fry every piece of electronics on the car. usually the first thing to take place in an electronic component is power regulation. when you hit it from the backside, your hitting all those resistors and diodes and chips backward with a full 12v load.

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.

Q: i have a pyramid ps52kx power supply and its powering a car amp for my room(dont comment about the set-up it works) but its drawin gto many amperes my question is can i just put a larger amperes fuse in so it wont trip?: Nope. That would be unsafe. Fuses are sized for safety. Oversizing a fuse will cause the supply to overtheat and possibly catch fire, of not weaken the components and produce less current than they do now. What you want is a power supply with more peak power.
