Review of installation procedures and performance review of Pertronix III electronic ignition conversion kit.
My friend Pat Skelly finally had enough of the points issues with his '62 GT Hawk.
The new Echlin points he put in a month ago 'broke' while down in Daytona Beach over Thanksgiving weekend.
After getting the GT Hawk home, Pat ordered a standard Pertronix kit for his Prestolite distributor.
Turns out the kit sent was not correct for his particular Prestolite.
(Note: Always get the Prestolite distributor tag number before doing anything)
When we determined that the standard Ignitor kit as a no-go, we did the homework.
Turns out Pertronix does not make a standard Ignitor kit for Pat's distributor.
However.... While on that page it was noticed that Pertronix does make an Ignitor III kit for Pat's distributor.
When looking at the spec sheet, it was noted that this kit also fits a stock Chyrsler Hemi V8 distributor with dual points.
A call to Pertronix confirmed that Pat's distributor number uses that kit, so Pat ordered it (along with the matching coil).
This morning we put it in. Here's the skinny....
This kit consists of the pickup module already mounted to the upper distributor plate, and that plate is mounted on a swivel bearing to the lower plate.
Remove the vacuum advance.
Remove both the points mounting plate and the plate under it (attached together).
Cleaned and lubed the mechanical advance mechanism underneath.
The new Ignitor III assy slipped in and was mounted using the existing screw (the distributor cap clip mount screws also mount the plate assy).
The new wires were pulled through the body hole, and the length of the red/black wires were adjusted in the grommet to allow the advance plate to move without binding the wires up.
There was a little braided wire ground strap that needed mounting to the lower plate.
Simple screw deal, but I did put a drop of Loc-tite on it...just to be sure.
Vacuum can reattached onto the new plate pivot pin and the microscopic danged clip (that has a mind of its own) gets reinstalled.
Installation of the distributor is straight forward (especially if you have marked the distributor body position, and the rotor position.
Slipped right back in...
Put hook ends on the red/black wires (rather than the ring ends)...
I'm sick of dropping little things under a car in the driveway with leaves underneath...
Mounted the new coil. Checked the wiring.
The Ignitor III takes a full 12v wire from the run terminal on the ign switch to the + side of the coil (instead of the pink resistor wire).
Double checked the wires were installed per the instruction sheet.
Snugged the distributor mount bolt and then loosened it just enough for me to be able to push the distrubutor around by hand.
Put the air cleaner back on...
Had Pat hit the key.
Engine immediately started and purred... SMOOTH.
Blipped the throttle a few times and listened to it.
Readjusted the idle mixture scres a bit (mostly just to feel where they were at).
Hard blipped the throttle to feel the timing adjustment and played with the base timing just a little bit.
Liked the way it felt and locked 'er down.
Did one more idle screw adjustment (just to make it look like I was needed)....
Buttoned 'er up and sent Pat out for a test drive.
I could hear Pat's engine from a couple blocks away when he 'got on it'.. You could hear the AFB secondaries..
His 1-2 shift brought an audible chirp.
Pat came back with this huge grin on his face...
'Nuff said.
Conclusion: Kit is real nice.
Even has an adjustable rev limiter built in (factory pre-set is 5500 rpm, so we left it alone).
Made the engine noticeably smoother and a mid range spark scatter issue disappeared.
IMOHO... This kit is worth the money.
So... If your listing offers both the Pertronix Ignitor base kit AND the Ignitor III kit.... I'd look real hard at the Ignitor III kit.
Took a couple of videos of the drive by, and of the ride along... Will try to post them later.
(ad copy)
- Adaptive dwell maintains peak energy throughout the entire RPM range, reducing misfires while improving engine performance
- Peak current level is reached just prior to spark for maximum energy without the heat build-up, increasing coil performance and module reliability
- Adjusts spark timing at higher RPMs to compensate for the inherent electronic delay
- Senses startup and develops more energy for quicker, easier starting
- Senses crank orientation from either the distributor cam lobe or a PerTronix magnet sleeve
- Thermal clad surface mount construction for high performance reliability
- Memory safe function for user settings
- LED user feedback for rev limit confirmation
- Built-in reverse polarity and over current protection shuts down the system, preventing component damage
- Legal in all 50 states and Canada (C.A.R.B. E.O. #D-57-8)

Pat's dist'r tag # is IBP4108 which shows no Ignitor kit, but does show an Ignitor III kit (see pic)
And... Here's the Chrysler listing in the app guide (for IPB tag's)
Now, Pat's is a single point dist, so perhaps this fills a hole in the Studebaker world...Maybe?

Here's a mediocre video of the first drive after install....
