Q: I bought a Yamaha subwoofer from some dud for $40 and the little red and black things don't workthe subwoofer has built in power and umm I tried plugging in 2 different speakers and they don't work.the hole to put in(red n black) is this screw and I'm guessing you put in the output right? is there anyway to fix this?model no. is YST-SW150
Take the bass driver out of the cabinet, take a flash light and look inside to see if you can see any lose wires, or damage if you do see lose wires solder those wires back where they belong reassemble the unit and try it outif there is something else wrong and there are no lose wires, you may have to replace a resistor or relay or it could be a fusedownload a service manual from the Internet and use that to find the fusecheck all components for damage or leakage.if you find something that looks blotted or is leaking look in the service manual for the proper value buy a replacement part of same value and replace it.but just try replacing the fuse firstfuses come in all sizes and shapes so sometimes you cannot tell where it is just by looking
Q: I turned on my truck the other day and suddenly my radio, dome light and power locks did not work. I wouldn't think all of these would be on the same fuse, but I don't know much about that stuff. Could it be a bad ground wire?
Radio and dome light are commonly on same fuse in many vehicles today. Depending on what you drive, the fuse panel could be at the end of the dash on the driver side (have to have the door open to find it) or under the dash on the driver side, or under the dash on the passenger side. Some vehicles have a secondary fuse block in the engine compartment, but this is not where the radio/dome fuse would be. Good luck in the fuse replacement.
Q: 2000 malibu power windows will not work at all. replaced the circuit breaker and still does not work
you may need a new regulator (the motor may be bad this comes with new regulator) have some one with knowledge of automotive electrical systems confirm
Q: I have looked at the circuit board looks fine.Is there a commen component that gets burned out?
Sounds like it blew out a circuit or a resistor or a diode.
Q: I am trying to fix the a/c and i need to find the relay. I have to fuse box but cannot locate the relay and thats where i found the problem to be
You can get a Chiltons and Haynes Manual for or jeep at Auto Zone, Parts Plus or even the part department of a jeep dealer. The wiring diagram is in these books.
Q: I have this hot tub that froze and busted a lot of the lines going to the jets. I replaced all these and turned the power back on with one of the gates still in the closed position. Not usre if I damaged the pump or what but I can't get it to do anything but blow fuses. The readout says it's overheating. I took the motor cover off and spinned the porpelers and they turned good. Also the heat senor has melted out of the inline water heater and was wondering if these are replaceable. THis unit has two pumps and it is a fourwinds model 700 maverickThanks for any help
get two girls, that should unfreeze the tub or whatever i stopped reading after the first 5 words
Q: Hi everyone, i hope you can help me out but i have a 92 grand am with a OHC quad 4 engine, 179407mi. I am trying to start it up and the engine turns good but not cracking up, Put new spark plugs and reconnect the ignition components back up, except there is a red wire tip clamp that needs to be connected back up, (WHICH IT WAS ALREADY OFF BEFORE TAKING COVER TOP OFF) i look and look and look for find where is goes and cant, also when you turn the key to the ON position i don't hear the fuel pump hums like it usually does, I ran outta gas a few times and wonder did the fuel pump shut off? or going bad? or just a relay/fuse? which i hoping that it is a relay/fuse, so please anyone can you tell where i can find the fuse/relay? and what does it looks like? and any more tips i need to know?
Sounds like the fuel pump fuse.try looking under the dash or on the side of the dash when you open the door.if it isn't there it will be under the hood.I would reccomend you go to your local autozone and purchase a $15 book on your car!! not only will it help you find those pesky relays and fuses.but it will also have a wiring diagram to show you where that disconnected wire goes.but don't fret if you can't find that because sometimes car manufacturers use wiring harnesses for different cars and option packages and that wire may not be used for your vehicle.although given it's location my guess isthat it goes somewhere.Buy a book if you are going to be doing your own work on the car.it is a invaluable investment!!!!!!!!!
Q: I have an old Lennox unit. The AC still runs fine. Heater quit on me back in March. not sure if the elements or what. winter coming soon and need to get this up and running again
Check the fuse's first. If they are good and the blower fan motor is running, the problem is probably either the heating elements or a disc limit is bad. The best way to check these components is ohm them out with a multi-meter. If you have not worked with electricity before I would call a qualified service tech to check on this problem as you are working with high voltage and it can be very dangerous. When you find which part is bad you can call a certified Lennox dealer (just look in the phone book) and give them the model number of the unit. Lennox is very good about keeping parts in stock even on older units.
Q: . since then my battery won't hold a charge overnight . the battery's fine, altenator's fine , and starter are fine . personally I was told it could be a fuse or something electrical ?? It run's fine once it's jumped and hold's the charge during the day while i'm using it but something is drawing it over night any suggestion's please ??
Sounds like you've got what they call a parasitic draw. That means there's some component on the car that's continuing to draw power from the battery while the key is off. I can safely say its not a fuse because when a fuse blows it stops whatever current draw made it blow. On an Explorer first thing I'd check is your ABS pump. To check it shut the engine down then listen for a hum just below the master cylinder in the unit mounted on the frame. It'll be the one that has several brake lines coming from the back end of it.
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!
