Q:i have a cb base on my home i was connectin the cb on my power supply and i put the wired rong i switch the way is supost to go and know the power swich goes on the cb wont go on i check fuse on power supply its good and radio is good in the fron of the power supply i have 2 button for positive and negative i think the problem is there fuse never burnplease help my question thank you god bless you

Does the power cord coming from the cb radio have a fuse? if so, it is probably blown. If it does not, then you may have fried a diod or other component on the cb radio circuit board.

Q:I want to add a circuit to my car to hardwire my gps and radar, and to run my rally lights.I have 10 gauge leads with a 30a fuse. I have 3 spst switches to run each. I have the appropraite fuses for each component.so to get to the point, i need to know how, if possible, to wire them in series so the voltage going to each is the same. This is my first time messing wiith electronics, and do i need to add any relays or capacitors?Thanks,Ben

A series circuit is one draw after another. If one doesn#x27;t work none work. Like Xmas tree lights if one goes out the whole string is out. I think you want parallel circuit. One hot lead and separate switches controlling each draw. It would be better to have individual fuses for each accessory. Do have 30 amp fuse on the main hot lead.

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 have a 150cc 4-stroke scooter , At first it was starting fine but over time the stator fryed and hade to be replaced and after replacing it did not give any spark. so i tried changing the cdi and ignition coil . AND STILL NO SPARK any advice?

You got an open circuit somewhere, do you have VOM, tester?Did you replace or test the fuse?

Q:I have a (optimus stereo amplifier mpa 250) Every time I turn it on the fuse blows, I have it connected with the right stuff so I am not over ridding it. I disconnected everything from the amp and it still blows the fuse every time I turn it on. Not sure if I miss connected something when I dis-wired it again. Please guide me with this issue, I've been threw Two fuse bags and can't afford to go threw more. Should I get it checked by a professional or what? Please help out someone. Thanks.

That fuse collection is saving your amp. You've got a short circuit in it somewhere. Needs checking out. Take the cover off and look for burn marks in the mains-in part and on the circuit boards. You might have a burnt-out resister or capacitor somewhere or a badly screwed up transister especially in the output stage. Power transisters can get hot. They have heat sinks they get bolted to and heat paste to make a good junction so the heat gets transfered better, Check the wires all round for molten or burnt insulation. Sometimes it's just dust that builds up inside that causes the problem especially in vintage amps that may have running twenty years without a clean out. Sometimes it's insects that get burned to a cinder and form a carbon bridge between components. Carbon is a good conductor and then you get a short circuit. Make sure the plug is out of the wall socket and give the amp a brush out with a vacuum cleaner nozzle held close to the brush. A 1-2 inch house painting brush works fine.

Q:I accidentally put the wrong terminals on my Honda Accord 2002 EX. All of a sudden the alarm system starting going off and I immediately took the cables charges off the battery and the alarm went off. Now nothing inside of my car worksit is completely dead. I checked to see if my battery was dead but it still has some charge in it. There was no smoking from the fuse box or battery. Can anyone help me figure this out or tell me what could be the issue?

Check your fuse box. Maybe blown all fuses

Q:explain

They are used to protect the circuit from overloads, this prevents fires and protects components of the circuit.

Q:I got a new engine put in my saturn about 5 months ago, about 3 weeks after I got the engine put in the power locks and dome light stopped working. The alarm on my car would randomly go off if I set the alarm on it and then about 2 days later they just stopped working. I checked the fuse by my passenger seat, it is fine. I am not sure how to check if the relay is good though. If is not the relay what would be my next course of action?Thanks so much,Jordan

If you are sure that the fuse is still good, it could possibly be a relay but I'd probably guess that it's going to be a damaged or broken wire. Take a voltage meter and take your dome light out. Check to see if it is not getting a positive feed or a ground. If it's not getting the feed, follow the wire back to the relay and make sure the relay is getting the feed to it and that you get a signal to the relay when the door is open. Then you can determine where to start searching and if the power is getting to the relays or components. You should be able to find a wiring diagram on the internet if you can read them. Good luck.

Q:can fresh jump starting of battery (2 hours/10miles) or burnt fuse of horn/lighter cause this problem?thanks for all answers

it can even be the gas cap needs to be replaced thats how i fixed my problem

Q:Hi, I've had a lot of problems with my bike and I know I need a new one. Don't need to be told that. I own a 2005 R50x 50cc scooter. On my way home, the lights went off and the 'dash' went off including the rpm gauge. The horn, starter and full beam still work though. The fuse is fine and it isn't the battery. If anyone has a clue please let me know and the location of the components that may be affected. FYI, all the electrical bits are in the front not under the seat. Many thanks

make confident the two events are not basically coincedence. because of the fact the different adult adult males stated, with the ignition change off, there could desire to be no juice going to any of the lighting fixtures fixtures. With the change off, the only place wires would be energized is between the starter soleniod and the change. i'm doubting that's a shorted cord on the grounds that could in very almost all likelyhood blow the top-rated fuse. If the fuse did not go, you may fry the shorted cord and at perfect you have got a melted wiring harness or at worst a charred bike. i've got had shorted wires and that i'm speaking from journey on that count. If this subject happens returned, i could verify the ignition changeperchance squirt somewhat WD-40 down the keyhole.
