ignition coil mounting screws glow blue

[heehaw80]

opened the hood in the dark to check something, engine was running and before I turned on my shop light I seen that two of the four mounting screws were glowing blue!!!! Also that everywhere that all eight plug wires touched metal where arking!!!! I know I need plug wires but would that cause those screws to glow????

Hooooly hell I've never heard of this before lol... What engine do you have?

 

[MustangChris]

woooooooooow. replace your wires NOW. if they are arching through the insulation, they've been neglected for some time.

 

[heehaw80]

it has a 5.0 and the wires are only two years old

 

[MustangChris]

what brand wires?

 

[heehaw80]

X act advance auto brand they were put on the engine two years ago right before I got the car the receipt was in the clove box says that there life time warrentied

 

[MustangChris]

how are the grounds? battery corroded?

id still replace those in a heartbeat.

 

[the5.ohh]

get those off asap.. get a set of ford racing 9mm wires and be done with it. I have longtubes and I have no issues with my wires, and longtubes make everything a lot hotter than stock manifolds.

Not sure its the wires myself. How old is the coil?

 

[heehaw80]

about a year old

also check you chassis/motor ground... All your grounds really...

 

[heehaw80]

I have a ground wire going right to one of the starter bolts, put that on a week ago with the new rt o2 sensor

 

[ttocs]

sanded the paint/connection on both ends prior to installing it? I would double check it and your other grounds.

Cheap under hood glow. . If wires are arking replace them. I have some pretty much new. Also a coil..
I think your coil is grounding off the bracket. Check all your grounds. Specially battery to block..

I had the same thing typed out in my last post before I deleted it. Shouldn't it ground to the chassis just like anything else does?

I use to have my coil zip tied I don't think the coil is grounded at all. .

awww pics would have made this post even wayyyyyyyyyy better

The glowing is probably residual radiation from the Fukishima meltdown if I had to guess.

damn it, you bastard.

i was looking forward to solid tech.

*sigh*

 

[heehaw80]

replaced the wires with 9mm wires and no more arking and no more glowing screws must of bin from the spark jumping to ground and the coil already being grounded
