That's the wire that goes to the tachometer to show you the RPM of the engine. It's one pulse per spark. You set the number of cylinders on tach and it's then divides by that number to display the RPM of the engine.

First you need to dislodge it. I would use something like this tool: Then, before you go to remove the spark plug, take a shop vac and vacuum the piece out of there. If you hold the shop vac's hose half-way over the hole, the air turbulence should remove the small piece of debris. Also, if the piece is ferrous in nature, the hook I showed above should ...

Although this question can raise differing opinions the very basic answer is yes you can use non OEM parts. In some cases they offer better warranties than the OEM brand. Aftermarket parts are in general made to the same specifications as the OEM part. You do want to be careful with your sources of aftermarket parts. Buy only parts from reputable suppliers. ...

This varies a lot by model, era etc., but a general overview: The first thing that happens is the ancilliary electrical systems are powered: Lights Radio (often the radio will be permanently wired, but this varies) Windscreen wipers Dashboard gauges Fans Anything that runs off switched ignition but also the Engine control unit, or ECU, which is what ...

This sounds like there is an issue with the ground at the battery. Sometimes it appears there is a good connection there (especially when using side post terminals), yet there is only enough of a connection to allow the low amperage stuff to work. Then, when you turn the key, the starter starts to engage, but then continuity is lost because there is not ...

The purpose of turning the wheel one turn is to put the wheels at a cant (other than straight). This is especially important on standard shift vehicles so it cannot just be put into neutral and moved. It just gives one more weapon in the arsenal against car thieves. The action of applying the club should be, before you turn the ignition off, turn the ...

If your motorcycle uses an electric starter (as opposed to a kick starter), the starter will draw far & away more current than the ignition system - like perhaps fifty times as much. A bike with only a kick starter only needs a tiny battery, while one with only an electric starter requires a big one. When battery capacity is too low, generally both the ...

My only suggestions would be: Use compressed air, as Zaid suggested Use a narrow screwdriver Make sure you don't lose it - worthwhile getting a closer look at it to see if you can identify where it came from!

The answer was that the battery was bad. Apparently it was a cheap battery and the failed alternator drained it. Once it had been drained, it would no longer hold a charge. Replacing the batter with a new, good-quality (VW) battery fixed the problem entirely. One clue was that when I jumpstarted the car, all the symptoms went away -- no blinking lights ...

Something which might help you diagnose the issue better is to do an old school trick on your just replaced distributor cap. This would be to generously spray the inside of the cap and the rotor with WD-40. Many people use this as a lubricant to help with stuck nuts and such. The WD in the name actually means Water Displacement. By spraying this inside, it ...

When you turn the car off and remove the key, make sure the steering is not turned to one side. If you leave the car with the wheels turned you may load up the steering lock as the steering geometry tries to straighten up. You are able to get round this in the circumstances you describe by 'rocking' the steering wheel to relieve the loading on the lock as ...

Your mechanic seems to have repaired the fault by replacing the alternator. A faulty alternator will drain the battery as you describe and can be quite dramatic in causing other symptoms.

It will wear the engine internals more, as there is less lubrication. It's roughly equivalent to pulling the coil wire on a distributor and just spinning the engine for no reason. At that low of engine rotation speed, the oil pump is not providing sufficient oil. There's also possibility to cause extra wear to the transmission, as you're shifting into gear ...

I don't think it's good for the car, but I don't think you are doing any irreparable harm. I don't think mechanically it is causing you anything major, but you are probably causing spark plugs to foul sooner, carb (I'm assuming this is an older vehicle since you didn't specify) is probably getting gummed up, and probably more along this line. This would be ...

This code means you have faulty wiring/coil pack. Usually means a new coil pack. To find the coil pack, look at the top of the engine. Between the engines top cover and its manifolds, at the rear, you will see a manifold wide black block. It has a grey plug entering it from its right hand side. (Viewed from the front of the vehicle). This is your coil pack.

I did some research and found this can be caused by a dirty throttle body. I removed the air intake piping and cleaned the butterfly valves with throttle body cleaner. All good now!

The click sound means there isn't enough current (amps) supplied to the starter to physically turn the motor. Try hitting the starter (give it a decent smack with a wrench or hammer) while a friend turns the key. Check battery voltage (12.6 volts) AND cranking amps. check for a voltage drop and a parasitic draw. It could be a ground issue but I'd start with ...

Put a cell phone with video recording 'on' in the glove box and close it to confirm if the light goes off. Measure amps on the battery and then start pulling fuses to see if you can determine the system causing the drain.

An old PARKER'S guide to the Uno known starting faults says: Failed distributor vacuum unit. Two small wires inside distributor break after 8-9 years or 60K-70K miles. Crankshaft position sensor.

On the side of the distributor,youll find a little modem.This can also be a problem and need to be replaced every 30,000 ks to be on the safe side.I did not know some Unos came out with points very interresting. One of the most reliable cars really fantastic.

It sounds like you've got a pretty good idea what you're doing already! I'd start by replacing the points & condensor and regapping them, that way you can eliminate one potential problem immediately. The same with the fuel filter - all are quick and cheap and will need doing anyway... Do a compression check as well, to make sure that is good, and ...

The idea of turning the wheel is to have the wheels turned to prevent movement of the car. After you park, turn the wheel prior to shutting off the car. I would suggest turning them towards the curb. If the ignition is removed by the thief the wheel will be unlocked. If the wheels were straight he would be able to drive the car albeit only in a straight ...

It sounds like your car already has a built-in steering wheel lock so The Club would have no benefit other than a visual deterrent and in that case it wouldn't matter how you put it on

Bad crank sensor Well, it turns out that the 2nd bullet on my list of things not wrong was incorrect. I had "assumed" that the crank sensor was fine because I had just put a new one in not 3 months ago with a brand new harmonic balancer. Plus it looked perfect as far as a visual inspection. No odd wear or corrosion just a little soot built up on the ...
