Answer to: Knocking Noise from Engine BayWhat are you doing going flat out for 10 minutes, trying to blow up your engine? Were you watching the engine temperature? So it doesn't make the tapping noise while stopped with the engine running. Not very likely it's the engine then is it? It does make the noise while you're coasting in neutral speeds up and slows down when you speed up or slow down. Sounds like drive train. I suspect the U joint on a drive axle. If so, the noise is usually louder when you are going around a tight turn. It's not a difficult fix. Lucky you, I hope.
Answer to: Do brakes and wheel bearings need to be changed at same time?I agree. I'd also stay away from the "mechanic" who told you this. I would have somebody else check the rotor runout. It's a simple thing and will confirm the reason for the pulsating. Who knows, maybe you do need wheel bearings, but it's pretty unusual, and warped rotors are pretty common. If they are warped, replace them, don't have them resurfaced. They are not expensive. You'll have to replace the brake pad too. Why did this happen? Maybe you are one of those drivers who keeps their foot on the brake while they drive, overheating the rotors and ruining your gas mileage too??
Answer to: What's stopping my starter from getting power?Part of the starter circuit involves having the automatic transmission being in neutral or park. There's a switch on the transmission that has to be closed by the linkage. Try moving the shifter while you are trying to crank the starter. If you've got a manual transmission, the clutch may have to be pushed in, and again there's a little switch down there somewhere. If you have a voltmeter, you can see if you are getting 12 volts to the big starter terminal, probably not, and if you are getting 12 volts to the big relay on the starter that closes the circuit to the motor. Perhaps you forgot to hook up the wire to that relay? Or if there is just a big connector plug, take it apart and clean it, blow it out with compressed air and try again.
Answer to: Ground wire getting hot and meltingYou seem to have hooked up something backwards or a component is shot and is shorting. If you melted the ground wire, I suspect the alternator or the starter motor. First, I assume you've disconnected a battery cable while you are sorting this out. Using a charged battery with proper polarity, try touching the battery cable to the battery terminal with everything turned off and with a good ground cable. Does it spark? I like to use a clamp on DC ammeter for this kind of thing, so you can see what kind of current is flowing. Maybe you can borrow one. But it shouldn't spark, and if it does - disconnect both the starter motor and alternator wiring - they might be wired up backwards or something??? Now does it spark, or does the meter show current flow, because it shouldn't. The melting ground wire means something big time is wrong, but using a meter and disconnecting various circuits, especially the ones you messed with during your rebuilding, should show where the problem is.
Answer to: URGENT! Whirlpool refrigerator does not get cold at all?The usual things that go wrong with refrigerators are losing their "coolant" which would probably have to be replaced by a technician; the compressor going bad (same result) or the relay that runs the compressor dies. The last item is pretty common. What I do is listen for the compressor to come on when you plug it in. It makes a humming noise. If there is no humming noise, it's not running. Assuming you are not afraid of electricity, it's time for the volt meter. Is power getting to the compressor motor? Take the panel off the lower back of the fridge, clean off all the dust with a vacuum cleaner, find the power coming in, going to the relay and from there to the motor. Measure it at the motor first. If it's got power but is not running, wack it. Give it a tap with a block of wood and a hammer. It might be stuck, and sometimes this is all it takes. Not a good sign, but at least you'll know it's the motor and not something else. If there is no power to the motor, rejoice, it just got cheaper. Measure in and o...
