Spark at Boot

[aakate]

At night I can cut all lights out and look at each spark plug boot and see blue fire jumping off boot. I m bout out of options here, ive tried 2 sets msd wires 1 set fairly new fms wire and count less spark plugs. The problem still exist. Also everywhere the wires touch ground you can see blue like spark coming from wires.

My ign. set up is msd 6al, msd dizzy, blaster coil.

Also heads are alum. which each are grounded to block and from there to chasis then to battery.

Think ive done been through basics which are msd is wired straight to batt., tried different msd and coil, pickup ohms out, also get good ohm reading from msd ground at batt to coil ground at coil, tried 2 different rotor buttons and caps. Each set of wires have ohmed out good. I also get different characteristic when i swap pick up coil wires and eighterway the problem still there. Would gap cause spark not go to ground correctly, currently at 50 thou. Also dizzy has been phased in.

And currently using autolite 3924 plugs. Fuel has been cut back little to cut down on detonation. Timing is at 35 36 full advanced. Engine seems to have good idle and vac around 10 12. I can also feel the engine missing as rpms go up. Spark plus reads timing to be close but that read would not be correct if all the spark aint gettn to plug.

Has anyone even experienced this problem before.

I maybe tackleing all the wrong things.

Any suggestions would be highly appreciated.

Did you put the wires on the plugs dry?

[aakate]

I tried it both ways with and without silicone grease, same results

[banditmwp]

are you using new plug wires?

[EHardy1971]

Are any of the plug wires brand new,or are do they all have some time on an engine?

ha! Beat ya to it

[aakate]

After both sets of msd wires didnt cure problem, I took them off and got money back on them. As of now I put my old set fms on just to crank it up

fter 13 years in the automotive parts business, I have seen MSD's wire quality go to crap. get you a new set of FMS or Taylor wires, or even just a set of OE replacements to see if that takes care of it.

This is normal on high output ign. This sound stupid but start it up turn the lights off and run your hands over the wires you should see the spark following your hand. Its like the electric ball in Spencers. Thought the same thing about preston car last year. Call MSD they claimed that to be normal.

Damn your OLD:jester:

fixin get new set wires still in debate on which ones to use maybe taylors or race moroso or something like that

not my fault I needed a JOB in high school :slap:

and u can fell vibration in wire too

Yep I think we were darning each other to grab a wire to see if we'd get the shit knock out of us:jester:


I'd pull the rpm up to where the miss is pronounced and pull one wire at a time off the dizzy. If none change show a miss suspect a injector

:werd: I have Accel super stock on mine (not the cheapo base model yellow ones),with the boots bonded onto the wires.$40,and 5 years later,still no problems!:nice:

Try routing your wires so that they are not laying on anything metal, try setting your SP gap @ .040, and make sure all your factory grounds are still intact.

yea i like that feature, the moroso race wires are like that, $120+ though at summit

ok, i agree that was going to be my next move when i get wires in, waypastcrazy suggest 45, so somewhere in there should be close

fixin get new set wires still in debate on which ones to use maybe taylors or race moroso or something like thatI have a set of Accel 300+ wires and a set of ford racing wires,Both do this, you dont have a problem if the motors not missing or skipping.If it was arching off something metal when you touch it it will shock the hell out of u.Its just a lot of voltage goin through the wires.

I agree with the guys who say it's not a problem. My current car doesn't do it (stock coil and ignition), but my last car had a 300+ accell ignition and boy would it ever show the lights under the hood at night. Engine ran like a sewing machine too.

Taylor wires here and no problems, Use dielectric grease and route the wires away from each other and use wire seperators/isolators.

the grease really helps bind and concentrate the energy

No light show here, running a 6A and B'laster II with taylors.
