If Your Motor Won’t Crank, Examine These Things

July 21, 2011 | Author: | Posted in Vehicles

One of my customers a few years ago – who was stranded at the shopping mall, once gave me a call for help. Her auto would not fire up, it wouldn’t even crank over. I could drop by to examine her car for her as I was luckily about five minutes away from her. The problem was with the connections involving the terminals of the batteries. There is a quick and easy repair for the battery cables, but sometimes they do loosen over time. That was exactly what had happened in this situation. I was able to just tighten the terminals where they clamped to the bare cable ends and she was on her way. If your engine requires replacement components contact engine parts Atlanta.

In case the motor fails to make any crank at all, the battery is often the culprit. There are many instances regarding unfastened or corroded auto battery terminals resulting in cars being towed. If the auto engine doesn’t crank over at all, the first thing to look at is the battery and terminal connections. Switching on the head lamps and pressing the horn is an useful method of looking at your automobile’s battery. If the battery is any good at all this will be a quick preliminary examine. You could have a look at the wirings around the batteries assuming your horn and head-lamps aren’t functioning. I leave the lights on while trying this so I can tell if I’m making a better connection when moving the battery terminals.

A load test with a battery tester is the next step after checking the connections at the battery. One indication of an aging battery is that the engine doesn’t turn over immediately. At times, you will find that the batteries can go bad quite unexpectedly. Sudden alterations in the weather conditions might result in previously unnoticed issues with battery performance. Significant changes in temperature will effect the ability of a car to start. Batteries will need to have a good charge before they can be correctly tested. Modern battery testers will indicate if the battery has a sufficient charge to be checked.

Alternators that can’t deliver an adequate charge can lead to a raft of problems with the auto. It’s always a good idea to look at the alternator to make sure that the output is within the manufacturer’s specifications. Test related equipment is available in the components store or auto fix shops to look at the alternator output. The will test the voltage and amperage of the alternator output to ascertain if it is functioning correctly, they can also check to see if a short circuit is draining your battery.

Starters can have an open circuit or draw too much amps. After checking to make sure a good battery is installed, look at the big cable connection at the starter which is the 12v one that comes directly from the battery. Then examine at the starter solenoid Maintaining a watch over the power supply when you fire up the auto. If power is going to the starter solenoid but the starter is not engaging, most likely the starter has an open circuit or is binding. At times the starter can be tapped with a hammer while the ignition is in the fire up position to get the car to fire up. This is just a temporary fix to let you to get your automobile to a repair shop. I’ve used this approach many times to avoid the need to tow the auto. You can test your starter to see if it is putting too much strain on the battery. This can happen when the starter begins to drag or bind and puts too much of a toll on the battery. The amp draw is measured with a battery and electrical system tester to see if it is excessive.
