Where do you connect negative clamp?
Clamp the negative cable (black) to the negative terminal of the good battery. Clamp the other end of the negative cable to a clean metal part of the engine (like a bolt head or bracket) in the car with the weak battery. Keep the clamp away from the battery, any moving parts and the fuel system.
How do you charge a negative ground battery?
Connect the negative, or black, cable from the battery charger to the negative battery terminal by squeezing the alligator clip at the end of the cable so that the jaws open. Place the jaws over the terminal and slowly release the clip so that it is firmly attached to the terminal.
Is it safe to use the negative terminal of a car battery?
Your question is a bit unclear but the negative terminal of car batteries has always been wired up as ground. It is easier (and generally safer) to use the chassis frame ground as sparks are hopefully far enough away from the batteries to not ignite a hydrogen explosion from a charging battery.
How do you connect a car battery charger?
How to connect a battery charger: Verify that your car battery charger is in the off position before starting. Connect the positive lead from the car battery charger to the positive terminal on your battery. This will likely be red with a plus sign. Connect the negative lead from the car battery charger to the negative terminal on your battery.
How do you charge a battery with a negative cable?
The only way to charge the battery when the negative cable isn’t connected to the terminal is to attach the negative clip directly to the terminal. If you don’t want the cables connected then you’ll be forced to clip directly to the terminal.
Is it better to ground the chassis or the battery?
It is easier (and generally safer) to use the chassis frame ground as sparks are hopefully far enough away from the batteries to not ignite a hydrogen explosion from a charging battery. The hook up order I was taught was “positive to positive, negative to ground”, where the “ground” meant the chassis of the dead car.
