If the 49 dodge truck is still on it's original 6 volt electrical system it is positive ground. All 6 volt auto systems are/were positive ground. All 12 volt systems are negative ground.
I believe they were all built that way, yes.I believe they were all built that way, yes.
No, the Chevrolet Volt is not designed to be flat towed. Towing it with all four wheels on the ground can damage the drivetrain components. It is recommended to use a flatbed trailer or a dolly for transporting the Volt.
Not enough info. The only "12 volt outlet" that is remotely standard is the lighter socket in a car. Most if not all cars have the negative side of the battery at ground, which is the outer shell of a lighter socket. So the center contact is positive. If you are asking about any other 12 volt outlet, you need to check it out with a meter, or get a diagram for the system.
Connect the positive terminal on one battery to the negative terminal on the other with heavy wire and battery clamps. Connect the remaining positive terminal to the metal chassis of the tractor, and run the remaining negative wire to the items to be powered, with any luck at all, through a fusebox.
Voltmeter will give you opposite readings or will not work at all.
All Ford F100's from 1956 forward were 12 volt Negative ground.
All you have to do is turn on the car into ignition area and grab a voltage meter. Find positive first, to do this, find a good ground spot on your vehicle, such as a screw or metal, than with the red meter wire, go around til you find one that makes the volt meter go up... that is your power wire. Now, go from that wire, and check for your ground wire. Hold the positive wire onto the positive spot on your vehicle, and use the black wire to check until the meter goes up, that is your ground. Now you are done.
the module is under the coils, unplug the wires, unbot all three coils and unbolt the module. Make sure to use plenty of dielectric grease for a good ground
Find the cable that is connected directly to the frame or sub-frame of the car. If it is red, then Positive is ground; If it is black, then Negative is ground. More than likely (but not in all cases) the electrical system is Negative ground.
Main Batt far left side. Positive on the left, wire goes up and across top above radiator area and up to connection. (2 wires on Negative)1 Small wire goes up and 1 hooks to frame ground along with negative of left hand 6 Volt Batt. Positive of this Batt hooks to negative of the next 6 Volt Batt. Posative hooks up to 4 wires that goes up the right side of the compartment.
No all cars in the last 50+ years are negative ground to chassis exept for old versions of volks wagen
