Generally near the battery. The factory topically anchor the wires within reach of the body ground wire because it all goes in at once.
you have to have the car off the ground and look underneath it and you will see body mounts on the frame, there are approx. 8 to 10 mounts that hold the body to the frame.
Anywhere on the frame, engine, or body (if the body is grounded to the frame in any way).
There are 3 different grounds. Engine to body ground. Engine to frame ground. Engine to battery ground.
Speed is the relative velocity of a body (such as an athlete) given a frame of reference (such as the ground).
It runs from the negative battery post to the frame, block, and body.
On the negative post of the battery. Common computer grounds are on the thermostat housing, back of the cylinder head, sometimes on the intake, then main conductors are body to frame, body to battery, body to engine, frame to engine and frame to battery.
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.
Lifts a trucks body with spacers between the body and frame. Allows for bigger tires. Does not increase ground clearance.
anywhere on the frame or body that is cleaned of paint and rust.
No. That would short out and potentially cause a fire. The negative side will go to the frame or the body to ground.
I'm not a mechanic but typically the "ground" as you call it is actually the mounting screws for the device. The entire frame and body of a vehicle becomes a large return path for electrons used by all electrical devices. If your device has an actual "ground" wire, connect it to any metal connected to the body or frame of the vehicle. Electrically it doesn't matter; you are just trying to provide a return path back to the battery, which is connected to the body or frame.
follow the negative battery cable to the frame that is usually the main ground but there are many body tied ground cables throughout the car
