Why does my battery have intermittent starting difficulty?

If the battery has an intermittent inter-cell connector problem, the voltage will drop to very close to zero yet if the key is released the voltage will mysteriously go to nearly a full charge condition or whatever it was when the ground cable was reattached as mentioned earlier. I hope this is helpful.

Why does my Car start intermittently after starting?

A faulty alternator is typically intermittent, which would explain the intermittent issue you’ve described. Barring that, and assuming the battery and starter are indeed fine, I would next check the spark plugs and finally fuel injectors.

What should I do if my battery won’t start?

If you run into this type of problem a cheap voltmeter can become your best friend. If you have no starting current, check the “open circuit” (ground cable removed) from the battery and the voltage checked at the battery’s terminals. It will almost always be normal. Reconnect the ground cable and re-check the voltage.

Do you know the signs of a failing starter motor?

Knowing the signs of a failing starter motor, can help you diagnose the problem. When Diagnosing starter motor problems, always start with the battery. So, for your starter motor to work properly, your car battery has to be in; excellent working condition and fully charged.

What does intermittent no start mean on a car?

Share it! An intermittent no-start condition references any time where starting is possible sometimes, and other times the engine will not start. This implies that the difference between starting and failure to start is not understood.

When to know if your alternator or battery is bad?

If you check hours or days after the fact, then you won’t be able to smell anything anymore. Before you go out and order a new battery or alternator, test some of these different systems. If your alternator, coil, battery, or starter is bad, the car probably won’t start, and it definitely won’t be drivable.

Why does my car not start after a new battery?

Positive cable is brand new. It is not a battery issue since it is fully charged and brand new. The car would not start after the new battery was put in and the starter was put on. How does this affect a alternator? My old battery was six years old and junk, so we replaced it and boom all of a sudden now the car will not start.

When to replace battery, alternator, or starter?

When you check these three, always start with the battery. It’s most often the part that failed, and it’s also the cheapest part to replace. A car battery should last about four to five years. It is not made to hold a charge for that long, so it gets recharged by the car’s alternator while you drive.

What causes a car starter to not engage?

5 Causes of Starter is Not Engaging 1 Low Battery Voltage 2 Faulty starter motor solenoid 3 Starter motor Plunger or Pinion 4 Faulty Wiring to starter 5 Flywheel damages More …

Why does my car not start with a new battery and alternator?

With a new starter, battery, and alternator (assuming you have not drained the battery attempting to start it), the starter should attempt to crank over the engine. If the starter does not make any noise when the key it turned to crank over the engine, you have an issue with the fuses, or the circuit.

What happens when the starter relay is on?

When the starter relay is on, the starter rotor will start to move firing up the engine. The first thing you must check is if your battery has enough voltage to power up your car’s engine.

Is the positive cable on my new Starter brand new?

The new starter is in. And the positive cable is brand new as well and all other cables are tight and clean. There was a build up of corrosion on the positive terminal and cable so we replaced the cable and cleaned the terminal.

When do intermittent electrical faults occur in a car?

Intermittent electrical faults are the bane of the auto repair business. If an electrical component has failed, or there is an open or a short in a circuit, you can usually find it fairly quickly because it isn’t hiding from you. It’s a persistent fault that can be isolated by a systematic process of elimination. Not so with intermittents.

What should I do if my car battery is intermittent?

If it’s not the battery, be prepared, intermittent battery issues can be a pain to diagnose (and to live with). We had a stuck AC valve which would drain the battery in a night, but would only stick once a month or so…took forever to figure out.

What happens when there is an intermittent electrical problem?

If an electrical component has failed, or there is an open or a short in a circuit, you can usually find it fairly quickly because it isn’t hiding from you. It’s a persistent fault that can be isolated by a systematic process of elimination. Not so with intermittents. Chasing intermittents is like chasing ghosts.

What causes a short circuit in a car battery?

Removing corrosion from the battery terminals can prolong the life of your car battery A flat battery is among the most common causes of car breakdowns, often resulting in the need to book roadside assistance or for an emergency battery replacement. Short-circuited cell due to failure of the separator between the positive and negative plates.

What causes a car battery to go flat?

A flat battery is among the most common causes of car breakdowns, often resulting in the need to book roadside assistance or for an emergency battery replacement. Short-circuited cell due to failure of the separator between the positive and negative plates.
