Reviewerst Jump starters Why my car won’t start with jump

I think everyone ran into a problem when the dead battery won’t jump start. Unfortunately, this happens quite often. Many different factors affect battery discharge, such as age, cold/freezing weather, and overnight use.

Fortunately, it is easy to tell if the battery is low with an external power source. But what if even an external source does not help and the car won’t start with jump?

It often happens that when the battery is completely discharged or damaged internally, it can be difficult to start up again. In any case, the procedure should be described in the manufacturer’s instructions. It is very important not to disdain this and follow it.

In no case should you try to get into the battery yourself. In addition to technology, it also contains acids, which, as everyone knows, can cause severe burns. You can work with it only if you have protective gloves and glasses.

Jumpstart Not Working

Main reasons why cars won’t start with jump

First of all, you should understand that, like any device, the battery cannot last forever. Several minor factors affect its wear. Batteries are most sensitive to temperature extremes, climate and obviously driving conditions. No matter how expensive it is, it needs to be changed every 4-5 years.

Terminal connections also require care and attention. There is always a big use of the fact that they are corny, rusted or too dirty. In this case, the current supplied by it will be reduced in the amount of which, in fact, is not enough for charging. Double-check the quality of the connection and, if necessary, clean the components from rust.

The next candidate for consideration will be a generator. Its main task is to restore the electrical power of the battery, which was spent on starting the car. What’s more, the alternator also supplies current to electrical accessories when the engine is running. If you see a decline in energy, feel free to go to a specialist because your car won’t jump start for sure.

It is also worth considering the presence of an emergency switch. In fact, that’s the thing that prevents a car with an automatic transmission from starting if it is not in parking (P) or in neutral (N). If you are driving a car with a manual transmission, be sure to depress the clutch before starting the car. However, if the safety switch is damaged or fails, the engine cannot be started from an external source.

The last on the list of problematic items may well be a faulty engine. If you hear clicking or grinding sounds when starting or jumping, it is obvious that you have a problem with the starter. Do not even try to fix it yourself, rather trust a specialist.
