NO!!!!!!
No.
When charging a car battery, you should always disconnect the negative terminal first. This helps prevent any short circuits or sparks that could occur if the positive terminal is disconnected first while the battery is still connected to the car's electrical system. After charging, reconnect the positive terminal first before reconnecting the negative terminal.
The a sensor is bad, removing the cable resets the ecm
with the car running disconnect the negative terminal from the battery if engine dies alternator is no good
Hook up the positive first and the negative last. Unhook negatives first when removing.
To charge a dead car battery, you'll need a compatible battery charger or jumper cables and another vehicle with a working battery. If using a battery charger, connect the positive terminal of the charger to the dead battery’s positive terminal and the negative terminal to a grounded metal point on the car. If jump-starting, connect the positive terminals of both batteries first, followed by the negative terminal of the working battery to the dead battery's negative terminal. Allow the dead battery to charge for a sufficient time before attempting to start the vehicle.
It will vary from car to car, but the neg is usually black, and has a "-" sign. Normally the positive terminal is larger than the negative terminal.
To charge a car battery with a DieHard charger, first ensure the charger is unplugged. Connect the red positive clamp to the battery's positive terminal and the black negative clamp to the negative terminal. Plug in the charger and select the appropriate charging mode, if applicable. Monitor the charging process and disconnect the clamps after the battery is fully charged.
The car grounding system is typically connected to the negative terminal of the car's battery, which is considered the ground or negative terminal. This means that the polarity of car grounding is negative.
No, that is definitely not normal. You have a problem. Take the vehicle to your local auto parts store and let them test the charging system.
disconnect the negative (black) first then positive (red).
In parallel. IE: Positive terminal to positive terminal, Negative terminal to negative terminal. Same as boosting a car batery.
