The ground wire leads from the negative side of the battery and connects either to the engine block or to the frame of the automobile.
Likely a ground that goes to chassis.
The Chassis is the ground.
Connect it to the frame/chassis -- the major metal parts of the car, such as the walls of the engine compartment.
the hot wire goes to the starter and the ground wire bolts to the engine block.
Negative - (Black) is Ground, Positive + (Red) is Hot. Ground wire goes to Negative (Black) it goes from negative on battery to engine for ground.
That is a body to engine ground wire.
if it is a big power wire ( same size as the battery cable ) then it is the earth wire you should find that the battery has one wire going directly on to the engine or chassis there are different arangements the negative wire could be coming directly to the starter and if this is the case then the wire is just earthing the engine but in a lot of cases the starter is getting its ground from the engine and the engine gets its ground from the battery
There are several ground wires - if you have a specific one in mind, please state which one it is. Some examples include the battery negative to ground (usually the chassis) and the engine block to ground.
There usually isn't one. The vehicle becomes the ground, and since the alternator is physically attached to the engine, the case of the alternator becomes the ground. Note that the battery is also connected to the vehicle chassis, usually at 2 or more points, and that the engine usually has a grounding strap to some solid point on the chassis.
Follow the ground wire from the battery. The ground wire from the battery goes right into the starter/connected to the starter. Passenger side of the engine compartment under the engine.
Sounds like you may have a bad ground. If you have changed the original battery cable ends, the chassie ground wire may not be attached or may have a bad connection. there should be a wire that attachs to the negative cable and goes to the chassis. sometimes they are bolted to the fender well. Another thing you may want to check is the ground wire from the engine block to the battery or chassis.
Connecting the ground wire to the metal chassis of the vehicle.
