Can You Jumpstart a Car with a Bad Alternator

A bad alternator will prevent a car from starting because it didn’t charge the battery while the car was driving. Luckily, you can jumpstart your car with a bad alternator so you can get it back on the road and drive it to the nearest auto repair shop.

Make Sure The Donor Battery Are In Good Shape: The first tip is meant to be an easy one. When you get a jumpstart with a bad alternator, you’re going to want the other vehicle’s battery to be in good shape and have a full charge. The explanation is that your battery is going to draw a lot more energy from this other battery than it would usually be when you jumpstart your car.

Connect Jumper Cable: Connect the positive (red cable) on the opposite end of the jumper cables to the positive terminal on the car with the good battery.

Connect the negative cable (black) to the negative terminal on the car with the good battery. Connect the other end of the black cable to a place on the engine as a ground. This can be anywhere on the engine block that is clean and not painted or chromed. Never place the negative cable of the car to be jump-started on the battery.

Make Sure To Run the Other Car At Least 5-6 Minutes: When you need someone to give you a jumpstart, your car needs to be switched on and running for at least 3 or 4 minutes. Make sure that the jumper cables are still attached when this happens. Your car should also be switched off during this period. After those minutes have passed, try starting your engine, which has a bad alternator in it.

Turn Accessories Off: All your car’s electronic accessories need to be turned off (air-conditioner, heater, radio, phone charger, GPS, etc.) so you can conserve all the battery power available to you. Remember, your car must effectively engage the fuel injectors as well as its computer system. This means the jumpstart won’t work in anything less than sunny weather (windshield wipers and headlights will suck too much battery power). After you’re sure everything is off, you can start the jumpstart.

Remove Cable Of Bad Alternator Vehicle: Remove the black cable from the engine block. Remove the red cable from the positive terminal on the car with the alternator problem. Keep the cables away from each other while removing the black cable from the jumper car, and remove the red terminal.

Get To A Mechanic Immediately: If your venture proves successful, you should drive immediately to a mechanic. Note: You may only have 5-10 minutes, so if the shop is too far, you’ll need towing service. Also, avoid highway driving or major interstates. You need to drive slowly to maximize efficiency.

Here is the Answer of all suggestion:

Most usually with jumper cables, you ‘re going to have to keep them hooked up for a few minutes with the donor car running to charge the dead battery enough that the combination of the amperage from the jumper cables, plus the amperage available from the car’s much more charged battery, is enough to start the engine.

Unlike some others, the engine won’t stop as soon as you take off the jumper cables. It will continue to run until the battery voltage is so low that the ignition system and any other electrical systems needed for operation are no longer working correctly. This, of course, happens even faster if you have a high electrical charge, such as the high blower motor.
