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.
Can you touch the positive terminal of a car battery?
Always undo the ground (negative) first. Otherwise, if the spanner touches exposed metal whilst still attached to the battery positive, it can create a circuit through the car body which is connected to the negative. Also to know, is it OK to touch car battery terminals?
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.
How to tell if your car has bad ground connection?
Disconnect the negative battery cable and connect the probe ends of a digital multimeter — set to read volts DC — to the negative and positive battery terminals. Record the reading; you should get something in the neighborhood of 12.6 volts.
How does a positive ground car charger work?
The cable that attaches to the negative post of the battery attaches to the starter solenoid. 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. Diagnosing Positive Ground Electrical Systems

Can you run a 6 volt car on positive ground?
Positive goes to positive and negative goes to negative. This makes a parallel circuit. But make sure neither car touches each other! You can use a 12 volt battery to jump a 6-volt system with two precautions. Do not run the vehicle with the 12 volts, and have someone ready to yank the cables as soon it starts.
