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.

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.

Where is the voltage regulating system on a Dodge?
