And, as the weather gets colder, there is so much more to cover: how to winter-proof your car, how to drive cautiously in ice and snow, and how to trouble-shoot cold-weather problems. The alternator is meant to slowly charge the battery over time.Anyone with a new driver in the family wants to be sure that they're doing everything possible to stay safe in the road. If the alternator is bad and you managed to reach your destination, the battery voltage will be too low at the next start up. If the alternator isn’t putting out enough amperage to charge the battery, you know you’ll have an issue. For a car that turned off and didn’t crank over again after disconnecting the jumper cables after jumpstarting the car, more than likely there is an issue with the alternator and it should be tested. You should still be able to drive and possibly charge the battery if the battery is dead. The car should be able to run using the alternator. What If the Car Turns Off After the Jumper Cables Are Removed? It’s a good idea to take the vehicle for a road test after starting so the alternator can charge the battery. The goal is not to charge the bad battery but to send enough amps and volts to start the vehicle, where the vehicle’s own alternator should be charging the battery. Some say it’s a good idea to rev the engine on the vehicle with the good battery when jumpstarting, but the alternator is not supposed to provide a good burst of power to the bad battery-It’s supposed charge the battery once the vehicle is started. Start the vehicle and let it run for about a minute. Make sure all electronics like the radio and any switches are turned off. This will prevent too much of a draw that the vehicle with the good battery won’t have issues starting in the future. Start the vehicle with the good battery and let it run for a minute to give the battery a little bit of charge. Start the Vehicle with the Good Battery.Once the destination has been reached, you can retest the battery with the multimeter. This means you can take the vehicle for a drive to charge up the battery. Once the cables are removed, if the multimeter reads around the same voltage, that shows the alternator is still working. With the vehicle started, you can see if the alternator is charging the battery. You can connect a multimeter to the bad battery. Optional: Connect a Multimeter to the Bad Battery.In case the battery has shifted out internally, you won’t have an issue if something explodes. It also lets you know there is an issue with the ground if the vehicle won’t start, and it creates a fused circuit to prevent damage to either vehicles’ computers. Grounding to the engine can prevent an explosion of gases in the battery if the connection arches or sparks. Connect the Negative Cable to the Negative Terminal on the Bad BatteryĬonnect the negative cable to the negative terminal on the bad battery, or find a ground on the engine like a structurally integral metal mount.Connect the Negative Cable to the Negative Terminal on the Good BatteryĪttach the negative cable to the negative terminal on the good battery. Leave the black (negative) cable hanging from any metal it could ground to. Connect the Red Jumper Cable to the Positive Battery Terminal on the Bad BatteryĪttach the positive cable to the positive terminal on the bad battery.Leave the black (negative) cable hanging away from any metal it could ground to. Connect the Red Jumper Cable to the Positive Battery Terminal on the Good BatteryĪttach the red (positive) cable to the positive terminal on the good battery.
