Spark jumping king lead onto coil terminals
I cant figure out why this is happening. Car in question is a Vauxhall C20LET I know you may say what the hell you doing on here but its a common known thing that you ford guys know your stuff. ANYWAY!!!!
I thought i had a dodgey coil but i changed it for another one and its doing the same
Symptoms are - slight rough idle and misfire
Reason - Spark arcing from king lead onto the terminals of the coil. You can see and hear it plain as day jumping from one to the other.
Now the car is running off the power of its own battery just now due to myself waiting on correct alt bracket but i have had it idling from jump leads.
Parts new are, Leads, Rotor arm, dizzy, plugs (gapped correctly) just had a full engine rebuild and still waiting to run the dam thing in.
Also checked to see if earth was dodgey so i got a jump lead and connected it to the battery GND and the other to chassis - No joy
I changed the king lead for another one - Still no joy...
Video of how its revving is here - http://www.youtube.com/watch?v=7RYPmUbg_bk
Now we all know it takes the easiest way to earth.... i can think where the resistance is coming from.
Any ideas guys?? im a patient man but im slowly losing it with this thing!!!

to right its a weird one... im just gonna have to bite the bullet and order new bits.... The aint genuine GM but i think thats what il do this time.
Il swap the leads for magnecors.

Testing the future
i would make sure that the rotor arm is the correct one, and is timed correctly. if the gap is too large between the rotor arm and the terminals on the cap, the energy has to go somewhere and will as you say take the path of least resistance

Just swapped the leads and rotor arm for genuine GM equipment. Dizzy i am getting tomorrow... still doing the same. She's timed spot on so its has to be down to the dizzy.....
if not im gonna burn it. lol
