Q:I changed all the bad fuses, then I changed the switch, then I tested the motor by hooking up a 12V battery pack, and it worked just fine up and down. What else could be the problem and how do I test it?Also, the window and the door lock mechanisms don't work on the passenger front door, even from the master control on the drivers side door.

it could only be a few things. Make sure the new fuses are the correct amperage second check the motor for the window last check the grounds make sure there all tight

Q:I am having a hell of a time trying to find a 1.6 micro mini fuse for a circuit board with wire leads on them. I need ones that are fast acting (so far, I have only been able to locate slow)Is it possible that I can replace the 1.6 fast acting with a 1.5 fast acting? I have a 1.6 slow fuse with leads on them. But I heard that you shouldn't use a slow fuse with sensitive electrical components where there had been a fast acting fuse prior. (I would only be running at most 50w)Thanks for any help you may offer, I am much obliged

I'm sure that your 1.6a fuse will not be running at 1.6a, so I guess that a 1.5a fast fuse (Flink) would be ok, 0.1 amp is not a huge difference. Dont know about the wire leads, could you not fit a fuseholder instead and use this? maplin .uk/Module.aspx?Modu maplin .uk/Module.aspx?Modu

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?

Try recharging the battery first. You probably shorted the battery and may have damaged it beyond repair. A new battery should be all you need to do.

Q:I got infinity kappa 6.5 Components and infinity 6x9 kappa both are 2 ohm speakers, dual 7 inch touch screen tv radio has a 15 amp fuse, mtx jack hammer 4 channel amp which is rated at 400 watts rms x 4 @ 2 ohms birth sheet states 480 rms @ 2 ohms x 4, 800 max birth sheet states 895 max @ 2 ohms x 4 and has 2 35 amp fuse, and rockford fosgate tweeters ran of the radio 22 rms. just bought a die hard platinum battery and upgraded my ground and power cables under the hood with 4 awg cable. two 4 awg cables to the alternator and 2 to the ground and engine block one to the fuse box all 4 awg. my lights dim as the bass hits in idle should i get a capacitor or high output alternator?????????

Not familiar with that brand of battery but deffo go with the alternator, capacitors are little bit of a gimmick in my opinion. they do help to an extent they prevent surges of power being taken from the battery on each note but if your alternator cant keep up the battery it going to get drained and have a shorter life anyway

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.

Q:Every time I buy a little figurine or annual ornament, I am amazed at how crystal clear the glue is that holds the crystal together.Anyone know what kind of glue that is or what kind you think it might be?

NO, but you could call the factory or head office ask what they would use to replace a piece if it broke off I would think it would be the same as what they used to create it in the first place.

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 drive a 1997 buick lasabre and i just replaced the taillights. the brake lights light up, but the tail lights dont, whats wrong? im not a car mechanic so i could really use some help. the bulb is a double filament.

Check your fuse box. It could be you are not getting power from your dash switch to the lights.

Q:I was restarting my computer, and it started buzzing.It was coming from the mobo speaker, and now it won't turn on.On the front of it, the 3 and 4 lights are lit up.Can anyone help me?

It sounds like your speaker fuse blew. Check to see if the fuse is still intact, if it is, then you may have fried a component inside the speaker. Time for a new one in that case. If the fuse blew, you can easily get a new fuse. I had the same problem with an older set of speakers. They were really good ones with a subwoofer and all. I heard the buzz for a few days, then, Pfffft! it went out all at once. Fried components inside the speaker and had to replace the whole speaker unit.

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.
