Electrical sytem positive ground
red is positive on a negative ground system
There are 2 battery terminals. A positive or hot and a negative or ground. The positive is slightly larger than the negative.
Batteries are neither positive nor negative ground. It is the circuit itself that determines the common ground. For example: If I have two circuits, one needing 6vdc negative ground and the other needing 6vdc positive ground, the battery would be installed the same way in both circuits (positive terminal on the battery to the positive connection in the circuit, regardless of whether the circuit is positive or negative ground). The reason for labeling the ground as Positive or Negative has more to do with how the circuit is wired up, than the actual voltage source. The explanation for that is beyond the scope of this answer.
The 1937 Oldsmobile is negative ground.
Cars in which the positive terminal of the battery is connected to the chassis. They require specially designed components built for positive ground cars. The usual configuration is a negative ground (the negative battery terminal connected to the car's chassis).
Red cable to positive, black cable to negative.
The Suburban has a negative ground system.
The earth (Ground) on any car battery is negative while the live is positive.
Remove the ground cable. Remove the support arms that are in the way.Remove the positive cable. Take a ratchet,a 12" extension, and a 13mm socket and remove the holdown fixture located at the bottom of the battery. Install new battery. Reverse procedure. Done.
I doubt it but I am not 100% sure. It is unlikely in 1983 BMW was using a positive ground system. You can easily find out. Trace the negative battery cable and see where it goes. It is is attached to ground then it is a negative ground system.
Yes connect the positive first to the positive battery post, and then connect the negative ground to the engine somewhere and not to the battery.
Negative - (Black) is Ground, Positive + (Red) is Hot. Ground wire goes to Negative (Black) it goes from negative on battery to engine for ground.
originally 6v poitive ground
simple answer is ground wire is not properly installed
Center terminal is connected to the positive from the battery. Outside is connected to ground (-).
positive goes to the battery and negitive goes to a ground clamp on the frame..
You can test the fuel pump by touching the positive wire on the positive post of the battery. You will need to ground the ground wire.
In a negative ground system, hook the vehicle ground (frame) to the negative of the first battery, positive of that battery to negative of second battery and the positive of the second battery back to vehicle positive. ( starter or starter solenoid) If you are hooking 2 12 volt batteries in series you will have 24 volts.
Connect the positive clip of the charger onto the positive post of the dead battery. If the battery is located inside of a vehicle, connect the positive charger clip to a grounded surface--like an engine block--on the vehicle.
I connect a spare battery to the system with jumper wires, positive to an accessory post on the vehicle and the ground to a good engine ground. Keep in mind the vehicles positive battery cable will be hot even after the vehicles battery is removed.
Red is positive black is ground.
Answer Red cable (+) goes to starter solenoid and Positive side of battery Black (-) cable goes to engine ground. When disconnecting a battery always disconnect the ground cable from the battery first. When connecting a battery always connect the ground cable to the battery last.
