What is a 6 volt positive ground system?
What is a 6 volt positive ground system?
A 6-volt positive ground system runs the positive side of the battery to the frame of the car, causing the frame and chassis to carry the current (this was thought to reduce corrosion). When an accessory is wired back to the ground side of the battery, it completes the circuit. A 6-volt negative ground is the opposite.
Is my car battery positive or negative grounded?
Check the battery and identify the large cable that is attached to the chassis. For vehicles with two 6V batteries, only one will have a cable attached directly to the chassis. This is the ground cable. Follow it back to the terminal and check for a (+) or (-) symbol.
What kind of battery does a positive ground car use?
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.
Can you read 6 volts from a positive ground system?
The positive terminal of coil will only get a ground connection through the points or possibly a trans kickdown switch. With the ignition switch on, you should be able to read 6 volts to the negative terminal of coil. I think I see what you do not understand. With a positive ground system, the polarity is reversed from a negative ground system.
When did a car go from positive ground to negative ground?
Most cars switched from 6 volt positive ground to 12 volt negative ground together. One exception to this was the 1955 Packard, switching from 6v to 12v but not switching to negative ground. All British vehicles imported to the U.S. after World-War-II were positive ground, and many stayed that way until the 1960’s.
Where does the coil go in a positive ground car?
The positive terminal of the coil goes to the distributor (points) in a positive ground car. The positive terminal of the coil has another wire on it. This should be suppling -6 volts to the coil and distributor?
How does a positive ground system work on a car?
A positive ground system works by directly connecting the chassis of a vehicle to the positive side of the vehicle’s battery. This system effectively earths the vehicle as the chassis attaches to the battery using a positive battery cable. The cable is tethered to the battery at one end and the engine block at the other.

When did the positive ground system become common?
The positive ground method was common before the year 1954, and many vintage or classic cars, especially those from the United Kingdom, adopted the positive grounding system.
