SYMPTOMS OF A BAD BATTERY CONNECTION -

Having a good battery connection between the terminals and the cable clamps is crucial for having a stable supply of electric power in your car.

If that connection is faulty, it can cause an array of electrical and electronic problems.

Also, and this is very important, a bad battery connection can easily be mistaken for a more serious and expensive problem like a bad starter, a bad battery, or a bad alternator.

So, recognizing a bad battery connection on time may well save you some time and money.

SYMPTOMS OF A BAD BATTERY CONNECTION

1. CLICKING SOUND WHEN CRANKING

One of the most recognizable symptoms of a bad battery connection is a clicking sound when you try to crank the engine.

So, you turn the ignition key, and you hear a frequent clicking that is usually accompanied by the dashboard lights going dim and fading away.

In this case, be sure to check the battery clamps and terminals first.

2. SLOW CRANKING

Besides the clicking sound, there may also be weak cranking.

It much resembles when the battery is dying or when there is a problem with the starter.

Again, if these symptoms appear, check the battery connections first to avoid replacing the battery or starter for nothing.

3. THERE IS NO ELECTRICITY AT ALL

Another almost sure symptom of this problem is that when you turn the ignition key, there is nothing!

No, dashboard lights; no cranking. It’s like the battery is completely disconnected.

If you experience this, besides the battery terminals and clamps, you should check the cables to the clamps and the fuses.

Related to this, and this can be scary, you may experience random total electric blackouts while driving. So, if this happens, check the battery connection first.

4. ALTERNATOR PROBLEMS

A bad battery connection will also cause problems with the alternator and with recharging the battery.

The faulty connection prevents the electric current produced by the alternator from actually getting to the battery.

In most cases, the alternator will still charge the battery, but with a weaker voltage, and may eventually completely stop recharging.

5. FREAK ELECTRICAL PROBLEMS

Finally, you may notice freak electrical problems that cause confusion and may also lead to all kinds of unnecessary repairs and interventions.

Some of these would be dashboard warning lights coming up for no reason, appliances suddenly stop working, and so on.

All electrical and especially electronic installations are very sensitive to random voltage drops or the mentioned complete blackouts.

So, if you notice any of the previous symptoms, react on time to avoid this, as it can damage the car’s electronics.

CONCLUSION

Our recommendation is to always check the battery connections first if you experience any of these symptoms. Also, check the battery cables and the ground connection cables.

If you see a green/yellow buildup on the battery terminals and clamps, if you see that they are damaged or loose, and they haven’t been cleaned in a long time, do the cleaning first.

Just use some baking soda, sandpaper, or a file, and clean the inner parts of the clamps and the terminal, and make sure the connection is 100% good.

If the problems continue, then start diagnosing from the battery onwards.

Again, bad battery connections are notorious for misleading people into changing batteries, starters, alternators, and whatnot.
