Losing my mind. Arcing problem
possible fix. out there checking everything i can i was removing grounds to clean etc. I go to the stud over by the power distribution block and started to loosen it. Sparks flews and the stud broke. Hoping thats my issue. just gonna put a bolt n nut setup, sand up the contact points and pray to god i found the issue. Ill report back
why would i ground the positive lol. theres a ground stud by the power distribution block and it broke. i just replaced it but the car still appears to be running the exact same. doubt the arcing is fixed. ill know for sure in the dark tonight to. until then ill still be thinking of wtf.
actually with some posts ive read on here i could see why you are telling me not to ha

Im getting an arcing problem from all wires. I noticed the porcelin on the spark plugs glowing. Then following that got under the car to notice a laser light show. Arcing everywhere to the entire wire flashing bright white. Now ive noticed coil wire and even the coil itself is arcing out. coil is arcing to waterpump and to even the opti vacuum line.
new wires, new plugs, tried 2 coils. im losing my mind. just installed afr heads and a cam. started afterwards. grounds seem fine. i dont even know what to do now im out of ideas. anyone else ever solve this?
Thanks guys

ive got nothing else to try other than swapping the tune back to stock and or opti. dunno how the tune could do this though or opti. guess ill prayon one of those is it. when i feel like letting myself down ill go out there and try some more lol. thanks for the help guys

Kinda like what that car-talk forum said. Arcing means a lower resistance path to ground than through the plug gap. Take meter and measure resistance of each plug wire (<100 ohms for good wires), engine block to battery negative (<1 ohm), every circuit path u can think of. U could also remove the wires one at a time from the opti cap and measure to the spark plug anode (center electrode) <100 ohms then to the threaded case of the plug (open circuit). Did u drop the plugs onto the hard floor when installing? Wasting your time with computer tune but maybe not the opti.

didnt drop a single plug. the fact it did this on brand new wires on 2 seperate sets to me is crossing out wires. ill go ahead and ohm them. i got less than an ohm on all my grounds.

FYI, there are plug wire/cable testers made for aircraft:http://www.easterntech.com/e5.html. Not cheap though and i have seen them in use to find a problem myself so know they work. Don't know any auto motive wire testers that do the same job.
That high voltage charge ain't making it to the plug gap for some reason. Could polarity be wrong? I would look at the coil or opti having wrong polarity for some unknown reason.

I have heard a lot of talk of plug wires not being what they used to be just a few short years ago. I've used Taylors since my first plug wire change in my car over a decade ago and they have always been great. Bought a set last year, put them on and there were a few signs of arching out of the box. Something about the insulation quality going to ****/China made/ blah blah blah...
Post up a video. Would love to see it.

pulling wires off and ohm'ing them
old msd wire, one ohmd out at 120ohm then next one i check 1.100k ohm.. that dont sound good right? just pulled a taylor off thats on the car. the coil wire itself is at 1.170k ohm. arnt these supposed to be like 50ohm a foot or so for wires???

Heres what i found, take a look MSD:http://www.msdignition.com/page.aspx?id=3302 are like 50ohms/ft
and Taylor:http://www.taylorvertex.com/spark-pl...sal-wire-sets/ for like 350ohm/ft.
But we need to find out what is burning them up.

hmm at 350 a foot is what i have in those taylors. but the coil wire is what 6-8 inches? my msd coil wire ohmd out at 60ohms which is in their spec. i might try swapping coil wires and see if the coil wire itself quits arcing.
from what im reading plug wires are fine at 6000-7000ohm. now thats for stock wires. I dont know if a wire that is supposed to ohm at 200 and then ohms at 1000-2000 makes it bad or not?

I bought some name brand wires once a while back. After i put them on, i also experienced a power loss and rough running issues. Major light show at night. I pulled them off, and found that they were covered in dielectric grease. I cleaned it all off the plugs and wires and it fixed it. It ran fine for a while. But eventually bought some cut to fit wires.

Do you use anti-seize? if so how much? We had a guy come in the shop with missing issues and arcing, he just changed his plugs and put a **** ton of cheap anti-seize on them to where it wasnt even making a good ground.
Also have you tried a set of jumper cables from the battery and jut move your (-) around while looking for change?

Don't get discouraged man. U have a unique problem and are sorting things out. The more items u eliminate the closer u get and the more expertise u gain with your own car.
Hang in there and if u need to take a cold beer break to get back and try the six foot view of things.
