A low battery and/or loose or corroded battery cables can also prevent the starter from cranking the engine. Volvo s40key was stuck won't crank clicking from fuse box. This gives a little more definition to the target area as well as providing a good surface to get the 1/16" drill started. The noise usually indicates excessive ripple or AC voltage leakage from the rectifier bridge diodes. This noble engineering feat was fraught with troubles though as the sensor could (and most times did) get attacked by acid and the temp value would be wrong. Positive side will be more likely to have a build-up of crud or bad connection, but check both cables.
Starter clicks, makes a weird electronic sound, then metimes need to try 2 times to start. Volvo s40 won't start clicking noise when starting. Brushes: JN50-52003. I checked the output at the alt. Battery Drain Diagnostics: Response: Ross Gunn] To check to see if there is something draining the battery while the ignition key is removed, remove the positive battery terminal, and with a digital electronics meter set to "amps", measure to see if there is any current flowing between the battery terminal and the cable end.

Again, this will be a case where the engine cranks over, but will not actually run. They can cause probs too, good luck hope this helps. I have looked at the fuses under the steering wheel & on the engine. If you can get the engine started and then apply 12 volts to the excitation terminal, the alternator will charge. Turn up the volume and rev the engine from idle to 2, 000 rpm and back down to idle. Volvo s40 won't start clicking noises. Ppl still look at threads for answers to similar questions that they would have nowadays. Corrosion on battery terminals. Symptom: Rapid clicking sound. Remove both cables, clean the terminals (wire brush), use the red & green felt rings under the cables to preserve the connection.
John Sargent] They all interchange. All is well to and thru the D+ wire. Replacing the starter motor AND the battery solves this problem most of the time. If all that checks out OK, I would suggest you get a volt meter, and when the voltage reads a little low, measure at the alternator: It should be 14. Hot weather batteries? You don't even have to connect the wire. Turn both cars' ignitions "off". You're supposed to clip the OEM chassis harness clip off and crimp the new male spade terminals on and install the late model socket so the new NSS can plug into it... You'll then be given a list of the alternators and starts by model year and application. Then someone told me to tap on the starter and when i did it the car started right up. These were most likely the original cables and the car currently has 325, 000 miles on it. Volvo s40 won't start clicking noise when turning right. When this wire is at ground potential, it is the same condition as before you start the car - hence the idiot lights are on so you can check they are not burned out.

If you did connect it, you will need to disconnect it when you stop the engine else it will drain your battery. This eliminates sparking near the bad battery, which may be outgassing hydrogen and could explode. Car Not Starting: My Car Was Functionally Okay, All of a ..., Page 2. This excites the coils (electromagnet) and the alternator gets the magnetic field it needs to start charging as soon as the engine runs. With all the heat under the hood, the electronics will eventually fail.
Check ground connections, the wiring harness, and battery condition. Simply touching the jumper wire to the terminal will cause the alternator to start charging, and remain so as long as the engine is running. A difference of more than one volt would indicate faulty diodes and the need to replace the regulator. With a fully charged battery, either from your battery charger or the alternator, disconnect the battery and measure the voltage, measure it again 12 hours later and it should be virtually the same, maybe. On occasion it will not start and I get a clicking noise from what sounds like the engine bay area! Do NOT drop the starter, which may fracture an internal motor magnet. Clicking noise from starter, then starts. Don't attach it to the terminal clamp; we want to test the whole circuit from end to end. Check cables for broken or corroded wire strands, worn insulation and defective connectors. NEVER disconnect battery with engine running! It will also happen if the alternator is not generating any current.

Try measuring the voltage at the alternator output terminal and battery pos terminal with all utilities (headlights, rear window heater, fan etc. ) If they look really corroded, you need to clean the battery posts and cable connectors or replace the cables and try to start the engine. A Digital Multi-Meter's (DMM's) accuracy and digital display make regulator/alternator diagnosing and adjusting easy. When looking for the reason, you should start with the most obvious causes that are easy to diagnose: weak battery, and poor electrical connection. On the rear case half, and how is the rear case half attached to the front? Remove it and you'll probably find the two brushes (two black square spring loaded shafts) worn out. It is a microscopic or larger film of corrosion that can build up on both positive and ground connections with a preference to the ground connection, however auto's positive connection are just as susceptible. 4) It could be the battery. Does anyone have any ideas? Requirements: The engine of both the vehicles should be off, and the transmission in Park. Tip from Paul] The book "Bosch Fuel Injection Systems" by Charles Probst notes that after the jump and before cable removal one should put a load on the car by turning on headlights or the rear window heater. In the remainder of these cases, the flywheel ring gear itself is either worn, or has broken or missing teeth.
It cranks right up with no hesitation when it starts. Randy Starkie] To keep the new, loger brushes from hanging up on installation, tip the assembly into place to position the brushes before straightening it up. The starter draws several hundred amps, and a connection that's not 100% is quite likely to drop most of the battery voltage across it. Loose Connector Nut. Corrosion occurs when the battery acid reacts with the metal terminals which can lead to loss of contact and reduced current flow. To know if your S60 starting problems are from dirty battery terminals, you need to investigate them. Charging Amps: With the engine idling and no load on the charging system (lights and all accessories off, battery fully charged), the amperage output should be relatively low (typically less than 10 amps). The regulator has attached to it a set of brushes that contact the commutator. The higher the car, the better, but I've always done it with the car sitting at jack height. You need a 1/2 inch six point 18mm socket (940; 740 may require 19mm) or a swivelling socket, a 1/2 inch universal joint, a large breaker bar, and enough socket extensions (with one about 36"long) to reach back underneath the car to where you can apply the proper leverage to get a firm grip on the bolt head. Adam Stadnick] If you put a jack under the transmission support crossmember, remove the four bolts holding it up, and carefully lower the transmission down a few inches (being careful not to smash the distributor cap if it's a head-mounted distributor) it greatly opens up the access to the infamous upper starter bolt. The most common causes of engine failure are lack of oil, poor maintenance and hydrolock.
