coil wire arcing

Home / Sin categorizar / coil wire arcing

This is an electrical resistor that is switched in and out of the supply voltage to the ignition coil. Save my name, email, and website in this browser for the next time I comment. It states the rerouting procedure should be performed before other repairs are done for misfires, surging or spark knock. Can you route the coil wire differently so it doesn't arc. See if that helps. It's arcing on the square metal frame that all of them have. You can also measure the resistance of each spark plug wire, but like coils, values may vary between wire brands. Pull the coil pack wire out of its pin connector by depressing the tabs and lifting up. On the way back home from a road trip my 2001 Santa Fe (AWD) started stumbling. happens to the copper wire. Typically it consists of a wire wound into a coil or helix. But we are talking about the LT1 so I suppose it can happen. The reactor of the arc suppression coil extinguishes the arcing ground by neutralising the capacitive current. ed. Continue wrapping it around the screwdriver, making sure that your wraps are as close to one another without overlapping. ed. Just a stab in the dark. Remember this was in the early 70's,but anyway what I did was to use. Car still runs, at idle it will miss and at higher RPM's while driving is "pops" (backfires). I checked the distributor cap and rotor, they didn't look bad. lol No I don't have the stock metal heat covers on them. Coil was arcing, wires were arcing with each other, the coil to distributor wire was arcing out almost it's entire length against the air cleaner. If a coil can't spark it will build voltage untill it can and if it has to blow thru the side of a itself to release the energy it will. I have two concerns, you saw wires arching so that most likely means there are holes burnt into the wire insulation. I can only see it at night when it's dark. Then when cured coat with a good layer of silicon. 4. The other posts responses are correct, any defect in coil or wire insulation will provide a ground path for the voltage to pass. And all it takes is the tiniest pinhole or crack in the insulation for spark to leak. This happens only at WOT. After reconnecting the wire to SP, engine doesn't die anymore, but still arcs sometime and on every WOT(wide open throttle) it … The ballast resistor lowers voltage after the engine is started to reduce wear on ignition components. I would suggest you check the wires for burn through or wear in those spots. At what point is plug wire arcing a problem ? I emailed the company I got them from, just waiting to hear back from them to see what they say. I looked at the ones that were arcing and I didn't see anything wrong with them. My 01 Jetta VR6 with arcing occurring on the coil pack near one of the spark plug wire outputs, happens during high humidity and moisture type … How were you able to reduce it? Are you using the wires with the stock metal heat covers? The overvoltage damages the healthy conductor at some other points of the system. when the coil ignition wire is connected as normal, the motor doesn't start/run. It's done it on three different coils. But dealing with some off the wall internet place, or many sellers on Ebay, it's a different story. alright this is a strange one (at least for me). Running kinda rough, and I heard a crackling noise...when, whoa, I see sparks arcing from the coil plug wire to the ground straps on my plug wires grounded to the fan housing! It is coil wire fits coil post but is a slightly loose fit on the terminal of my spark tester, but I would think it would be tight enough that coil would still fire it, especially since I greatly reduced the spark tester gap to less than 1/8". I'm Bob.. 1994 Z28, A4, Stall, CAI, Cam, RR's, 342 rear, LT's , CatBack, Tuned. Anyone have any idea what’s going on? The capacitive current over 4 to 5 ampere flows through the fault give rise to an arc in the ionised path of the fault. In a three phase line, each phase has a capacitance on earth. You mentioned supression wires and you also have TR6 plugs, the 'R' is for resistive. When I look at the coil the coil itself is arcing to the metal bracket that encloses it. This system has been working fine with the engine. With the formation of the arc, the voltage across it becomes zero, and therefore the arc is extinguished. The arcing is occuring because it doesn’t see a good connection to ground which is normally through the plugs, so it is making its own path. Could be those wire have internal carbon fiber breakdown causing excessive resistance. The grounds look good as well. http://www.youtube.com/user/MysteryBird1?feature=watch, http://www.youtube.com/watch?v=G-DpZpTcJaA, OTVC Top Mount Kit - CC Performance Parts LLC, VerticalScope Inc., 111 Peter Street, Suite 901, Toronto, Ontario, M5V 2H1, Canada. I guess it's possible tho. Work on getting the coil part solved and then go to the plug wires. They were recommended by a bunch of people on here. JavaScript is disabled. Crack the engine and check for a good spark at the spark tester. Show the direction of magnetic field and indicate the direction where the short copper wire will move. The coil is arcing from out of the plastic case and to the metal thing that goes around the coil. I'll try coating everything in silicone. Loosen the four coil pack mounting bolts with a socket. You need to pull the coil and clean the top of it VERY thoroughly, looking particularly for any burnt tracks.

Start near the shaft of the screwdriver so you can hold the wire in place with your thumb. Is it possible that a weak coil would cause this? Definition: Arcing ground is the surge, which is produced if the neutral is not connected to the earth. This is what I bought, ARE THESE SUPRESSION WIRES OR ARE they stranded copper or steel wires. Your email address will not be published. If you did not see a spark, remove the coil wire from the distributor cap. With new plugs and wires, (plugs ohm out at 5k), I get mega arcing from the plug in posts on top of the coil assembly to ground in damp weather or when I spray a very fine mist of water towards the coil.
