Yes, unless it is a Porsche built in the 50s.
The earth (Ground) on any car battery is negative while the live is positive.
Negative - (Black) is Ground, Positive + (Red) is Hot. Ground wire goes to Negative (Black) it goes from negative on battery to engine for ground.
The Suburban has a negative ground system.
The 1937 Oldsmobile is negative ground.
To jump-start a Porsche Boxster S, first ensure both vehicles are turned off. Connect the positive (red) jumper cable to the positive terminal of the dead battery and then to the positive terminal of the working battery. Next, connect the negative (black) jumper cable to the negative terminal of the working battery and attach the other end to a metal ground point on the Boxster, away from the battery. Start the working vehicle, let it run for a few minutes, then attempt to start the Boxster.
The ground strap is the battery cable that connects from the negative battery post to ground, usually the chassis.
probably because YOU HAVE LOW BATTERY! Also, to jump a battery, it is positive to negative, negative to ground.
Usually on the Negative terminal of the battery.
You "ground" it or connect it to a negative source that is connected got the negative end of the battery
The negative terminal does not go to the starter on a negative ground system. The negative terminal goes to ground.
The ground is negative
The quickest and best way is to look at the battery. If your positive cable (+) is going to the frame or body, positive ground. If the negative (-) goes to the frame or body, negative ground. I believe that a MF 35 is a neg ground system but use the check from above.
