Only one grounding wire is actually needed, just as you can actually hold up your pants with either suspenders or a belt. Most guys wear just one, and most cars have just one wire grounding the battery to the frame.
Where do you connect the engine ground?
A basic ground system is as follows: Always use a heavy ground cable and connect one end to the negative battery terminal, and the other end to the starter motor or engine block as close to the starter as possible. This will insure the correct ground path to the starter motor.
Why does my car have two ground wires?
The reason for the rubber mounts is to isolate the engine vibration and the resulting stress from the frame. Some older vehicles did use a single ground to the block. This required a second ground wire from the block to the frame or chassis.
What is PCM ground?
To answer your question the PCM gets it’s ground on the radiator support behind the drivers headlight. The motor is grounded directly from the battery and the second smaller negative cable from the battery goes to the radiator support.
Can a bad ground cause transmission problems?
Even more, bad engine grounds can also cause damage. If too much current tries to find proper ground unsuccessfully, it will choose an easy path through transmission components, transmission cable, throttle cable, wheel bearings and narrow ground wires, causing severe damage to these and other components.
Can a bad ground cause a parasitic draw?
A bad ground would not cause this. This is called a parastic loss. That is when there is too much current being drained from the battery with the key in the off position.
Does a 12v battery need to be grounded?
Yes your – wire should be grounded to the chassis, you can use some #8 wire for that, find a good place when there is a screw, or you can put one in. You need to scrape off some paint for a good connection, and then scew down one end, connect the other to the battery – terminal.

- Slipping or burned out AC compressor clutch.
- Intermittent failure of sensors.
- Damaged throttle or transmission cables.
- Hard starting.
Where is the best place to ground a car battery?
The best ground would be as close as possible to the starter or even to the starter itself. Iron, like the block, conducts well enough that there is no big loss in having the ground a foot or two away, as long as it has a good, solid connection.

Where is the voltage regulating system on a Dodge?
The voltage regulating system is a control chip in the voltage regulator circuitry that’s inside the PCM and cannot be repaired independently, the entire PCM must be replaced. helpful? I guess that Dodge must lie then. These are the wiring diagrams for that vehicle and both show that it has a fusible link (A111 Dark.
