not sure what your working on but no positive never grounds unless you are attaching batteries in series. but if you are using one positive and one ground then red is positive and black is ground. positive is the power feed direct to the unit being powered and black is the ground and if there is a white it is usually a neutral wire which then is also used like a ground.

There should be 2 cables to your battery, a positive and a negative. Negative is ground.

Positive ground simply means that the positive (+) cable bolts to the frame. HTH. -Jim

For the record there were cars that used a positive (+) ground system. Cadillac, for example, used a positive (+) ground system through 1942. After World War II the 1946 models were negative (-) ground. HTH. -Jim

The 1978 MG-B is negative ground All the MG-A series and before were positive ground. They also had two 6 volt batteries. Most all English cars of the 50-60's were positive ground.
