Can you jump start a positive earth car from a negative earth car?
YES! Of course you can jump start it – and yes you must make sure it is connected +ve to +ve and -ve to -ve – just make sure the two cars are not touching each other. So the earth on the donor car will connect to the battery -ve on the Minor, and the earth on the Minor will connect to the +ve terminal on the donor.
What is a positive ground vehicle?
On positive ground cars, the cable that’s attached to the positive post of the battery attaches to the engine block or chassis. The connections are opposite on negative ground cars. When charging positive-ground cars, put the positive cable on the ground and the negative on the battery or starter lug.
Which car do you ground when jumping?
The positive (red) cable should be attached to the positive terminals on each battery. The negative (black) cable should have one end attached to the negative terminal of the dead battery, and one end grounded.
Why do you jump a car when grounding it?
3 Answers. “Ground” is just a code word which, in this case, refers to the “current return common” circuit node. There is a complete circuit because everything electrical in the car, such as the starter motor, also connects to ground in order to return current to the minus terminal of the battery through the ground.
What is the advantage of positive ground?
The advantages of positive ground lie mainly in the sacrificial anode being the vehicle itself. A few grams of lost iron is less devastating than the loss (or corrosion) of the brass or copper connections in the vehicle.
How to jump start with a positive ground?
Re: How to Jump start with Positive Ground. 1. connect the cables directly to the battery on the car with the good battery, being certain not to allow the opposite ends to touch. 3. connect the negative cable to a good clean ground on the car with the bad battery, preferably directly to the engine block.
Can you jump start a 6 volt positive ground car?
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. 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.
How to ground a car battery positive or negative?
The person connected the jumper cables to the respective terminal on each car’s battery. When I was putting away the cables I noticed the instructions said to ground the cable on the car of the dead battery, and then indicated that the car would either be positive or negative grounded.
Are there any cars that are positive ground?
As noted, newer cars are negative ground, but there are still old cars on the road, mostly collectors or classic, that are positive ground, and to protect themselves from a lawsuit, the manufacturuer of the cables included that pos/neg part to cover there rears!

Can a positive ground vehicle be a negative ground vehicle?
Jack of All Trades, Master of None! yes just use the positive on the positive terminal and the negative on the negative terminal on the battery and the powered vehicle doesnt know that the non powered vehicle is positive ground, 12V D.C. is still 12V D.C. positive or negative ground.
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
