Customer Question
2000 2.3l kompressor lost...

2000 2.3l kompressor lost power to the rear coil which i resored by splicing the 2 grounds together. before it would start for a couple of seconds now it sounds like it jumped time

Mechanic's Assistant: Is the power loss consistent, or does it fluctuate?

Consistent

Mechanic's Assistant: What is the make/model of your car?

Mercedes c230 2000 model year

Mechanic's Assistant: Are you fixing your C230 yourself? What have you tried so far?

Restored power to the rear coil which did not have power by splicing the black and black/white wire to the front coil which had power

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Could this cause the engine to sound like it jumped time?

Hi,My name is Jay

When you spliced the black and black/white wires you caused the coils to all fire at the same time and will cause the rough running problem. you will need to disconnect the splice and do further testing to see if the computer is turning on both coils on black and black/white signal wires.

The black wires are not grounds but both go to computer and computer uses them to turn on and off the coils as it needs to.
