What causes positive battery post corrosion?
Battery corrosion is caused by hydrogen gas being released from the sulfuric acid inside the battery. As the gasses react to the ambient atmosphere, it begins to produce a corrosive environment. If battery corrosion is present on the positive battery terminal, this is a symptom of overcharging.
Which battery post is grounded?
Which battery post is grounded? Find the negative terminal on your car battery and if it is attached to body of vehicle then it is negative ground.

How do you ground positive battery cables?
Connect the positive cable of the deactivated charger to the positive post of the battery. Ground the battery by putting the clamp on the other end of the negative battery cable onto the negative post of the battery. Fasten the clamp by tightening its nut with the insulated pliers/wrench.
What is the difference between positive ground and negative ground?
A positive ground system works by directly connecting the chassis of a vehicle to the positive side of the vehicle’s battery. Most modern vehicles use a negative ground system that involves wiring the vehicle chassis to the negative side of the battery, and this has many advantages over positive ground systems.
Is the negative terminal of a battery ground?
The negative terminal of the battery is connected to your car body, so you can connect your siren’s negative terminal directly to your closest ground point (car metal body). There’s no reason to have multiple cables on your battery’s terminal. Cable harness will be more organised.

Can You charge a positive ground car with a negative battery?
When charging positive-ground cars, put the positive cable on the ground and the negative on the battery or starter lug. If you want to jump start a 6 volt positive ground car, the best way is to use another 6 volt battery of either polarity.
Do you connect a negative battery to a positive battery?
Whenever you connect another battery to yours (or a charger), always connect negative to negative, and positive to positive. Whether you have positive or negative ground, this rule always holds true.
What’s the difference between positive and negative ground charging cables?
The connections are opposite on negative ground cars. When charging positive-ground cars, put the red (positive) cable on the ground and the black (negative) on the battery or starter lug.
