Q:I have 5mm LEDs that Im using to make automotive tail lights with and I need to know what I use for surge protection.

Figure out the current draw, and use a slow-blo fuse in series. Why do you need surge protection in an automobile ?

Q:i changed abad bulb indash all was good until i ran the car now no lights

check the fuses one may have blown. if so change it and see if it blows again. if this happens, take the instrument cluster back out and check for a pinched or naked wire

Q:I put an aftermarket radio in a 2002 pt cruiser and at first all was good until I noticed a fuzzy ness to the radio stations so I messed with the antenna cord and all of a sudden the radio wouldnt power on at all. The fuses seem to be all good. All lights on dashboard work. It also says no fuse on the dash. Everything works but the radio and I think the power locks.

Check fuse #18 (20amp, yellow) in the Power Distribution Center box under the hood. This fuse has a plastic pull-tab on it. It's used to control Ignition-Off Draw IOD. The fuse is pushed in when you take delivery of the vehicle. The owners' manual explains that it's used to keep the battery from draining during extended storage. If it's blown, you will need to determine what caused it to blow. This 20a fuse won't blow unless you've added a load to the circuit or there is a component failure. It doesn't take much to blow the fuse, the addition of a stereo or alarm, or even the power window modification, if you wired it into that circuit. If you haven't added an additional load, and the vehicle self-tests check out OK, dealer service will need to diagnose the problem.Also check the fuses in the fuse box by the driver's left knee inside the car and a 40 amp fuse up in the power distribution box under the hood.

Q:Any place I can find a fuse schematic for a 2005 Honda Met 2? My daughter crashed hers and ,as I was cleaning it up looking for damage, I found a fuse loose inside her radiator and I see an empty slot in the fuse box by the battery (which could be normal - I don't know). I'm guessing it'scondition that it has been there for sometime, but there is no way for me to be certain and I also want to ensure all the electrical components work as they should.She bought it used so she has no manual. Is there somewhere I can find out which types/sizes of fuses belong in each slot without buying a $50 manual? I've never had a problem getting this info on a car, but can't find it for a scooter.

The honda dealer parts dept can look up schematic 4 - you

Q:I have a friend with a 1993 Chevy Lumina and it will not charge the battery for some reason. He just replaced it with a new alternator and had it checked to make sure it was good at the store he bought it. When we jump it off with another vehicle it cranks fine and runs.but then when you drive down the road it will die if you step on brakes.then try to crank it.and it is deadwill not crank.like a dead battery. We had the battery all charged up as the battery is only 1 year old. Even bought a new battery. Why won't this thing charge? It there some kind of other electrical component keeping it from charging properly? What about fuses or some other regulator or realy somewhere? The engine on it by the way is a v-6 and a 3.1liter.

There is an alternator fuse in the under hood fuse box . If that is not blown check the battery wire on the back of the alt for battery voltage .

Q:I have checked every single fuse under the hood and under the steering wheel. Still no radio, clock, or dome lights.

Double check the fuses tor the dome light and cigar lighter, its easy to miss a bad fuse If you have a test light or DVOM (multi meter) use it to check both sides of the fuse for power, obviously an open in the fuse is going to cause one side of it to have power and not the other. You will need these tool to verify the fuse is getting power, check the condition of the fuse, and trace the power to the individual components on that circuit. For backyard mechanics, Harbor Freight has these tool for the $5-10 range that work great for occasional use. Good luck man! If you need any further help with open / short diagnosis just let me know.

Q:1. What are the most common electronic components I would need to understand to be able to develop circuits and invent innovative electronic products? I know theres a resistor, capacitor, transformer etc.2. What are the functions of each one of them?

Resistors okorder

Q:I changed the bulb cause it was blown, checked the fuse but nothing. Is there another fuse or a seperate fuse for each reverse light. And where can i find a new board?

It could be the reverse light switch. I had one go out on a Golf with manual transmission. It was mounted on the transmission. The part was cheap and I replaced it myself, but it wasn't much fun. Pretty hard to access.

Q:I have a 1987 ninja 750. i bought it and it turned on with an old battery but needed to be jumped to start. i bought a new battery . a duralast the one you add the acid in and charge. but now it wont turn on. a battery before that i added a new battery but i mixed up the terminals (pos on neg and neg on pos) did that mess up the electrical stuff or fuses or am i doing something wrong. hope to hear some help.

james is right you MUST have blown a fuse or two and a blown fuse will keep electricity from getting to any thing and everything so double check all of your fuses and uhhh do something about your terminals i am hoping the reason you mixxed them up is because they arent marked and so you should mark them so you dont take a chance of doing even more damage

Q:I live in Klang Valley, Malaysia
