If just #1 is not getting spark, it could be the cap or lead. It could also be the reluctor gap [ likely it has no gap, is touching the pole piece & you get no spark on THAT cyl ]. It could be the gap is too big, but that is less likely if just one cyl is affected.
Use a GM HEI 4 pin module, mounted on a heat sink to the dist body. Less wiring, less connections to fail. Switch to an E core coil, which allows removal/bypassing of the bal res. And a spark with more energy, 0.060" plug gaps.....
Info & pics on the web.
The coil you are using determines whether or not a bal res is reqd with it. The Pert unit is just a 'switch' in this case that switches the coil current on/off. Bypassing/removing the bal res will burn out the coil if it is designed to be used with a bal res.....
No, you can retain the coil for use with HEI but you have to use the bal res with it if that coil is designed to use a bal res. You will not get the best out of the HEI unless you use an E core coil with 0.4-0.6 ohms pri resistance.
The best place for Pertronix products.....is on the shelf at Pertronix.
If you want a better ign system than the Chrys ECU, use the GM 4 pin HEI module. See post #26 & others.
Packard made plug leads for different manufacturers; these had a carbon track that carried the spark current. Very high resistance 10-30,0000 ohms. The carbon was also liable to break & cause hard to find misfires.
I saw on another forum that Packard now make wires with a heli wound conductor...
R/T boy has covered it well. The mixture is less dense as cam overlap increases. More distance between the molecules; flame front takes more time to spread; hence more timing [ advance ] needed to get the most productive burn. With really big cams, up to 50* at idle may be needed...
Semiconductors in the ECU can suffer from something called thermal runaway; basically, they overheat & their electrical characteristics change. They can return to 'normal' when they cool down.
If an ign coil is used with a low pri resistance, say 0.5ohms, then the power transistor in the ECU...
Have not read all the replies. Has the vac adv been hooked up? Every time the VA deploys, it flexes the p/up wires. Eventually the wires break.....& no spark.
I would try a new p/up or different dist.
This thread is a great example of where a little knowledge is dangerous....
OP, you need to get some help ON SITE from somebody who knows Chrys ign systems.
The magnetic pick up inside the dist. If the vac adv was hooked up & working, the p/up wires will eventually break because the wires flex every time the vac adv moves. Disconnect the plug & measure the resistance, should be 100-500 ohms; flex the wires while measuring checking for an open...
