Yea, that's what I figured. Even a hack like me should be able to set it up. I pulled the old one at no 1, dropped the new one in, but the rotor is pointing at say 60 degees different because the tang is not ground the same but I figure no big deal because I install the no 1 wire on the tower lined up with the new location so no 1 is no 1. I had to move the rotation on the disty because it's a little bigger than the stock one, no big deal, no 1 is still no 1 right. The rotor is still at no 1 and the wire above it on the tower goes to no 1. It started up ok, actually hit it at -10 from the get go. Easy, seemed like all was well except it didn't sound so good and the car was shaking like it was missing. Checked all the wires with a timing light and they are all firing. To get it to smooth out I have to advance it up to at least -20 and -30 is even better. I am wondering if the pickup tape is off or something? There isn't much to screw up on a disty change if you get all the wires where they go (which I triple checked) so I am a bit stumped on this one. Voltage to the coil is good, and like I said, it runs great at -30....

I'm running a holley 3310 with the acc pump tweaked and have it jetted and spring'd for my engine. Eddy air gap RPM manifold, eddy performer RPM cam, head work on stock heads, don't know compression ratio exactly as I didn't build it, but compression tests put me about 190 psi cyl pressure.
It's weird, it's like my no 2 cyl is "off" some. It smooths out once I have my advance set up to about 25-30 before (yikes)checked degree on camshaft last year when I replaced the timing cover and that was good. There's a noticeable difference between the old disty and this (high performance) one.
Any chance you broke/bent the #2 plug wire? Wires laced correctly?
Check the rotor and make sure it's on correctly. Remove it and turn it upside down. Look underneath near each of the screw holes are. One side had a small male square, the other side a small male circle. Make sure they're oriented correctly on the dizzy. Check the PN on the module while you're at it and confirm it's correct
You're capping the vac pot while setting the initial, correct?
Going by your combo you probably ought to be near 15* initial w/ silver springs and the 20* limiters.

Yeah, it should be simple as pie...
When you checked coil voltage , did you do a loaded test or did you just turn the key to the RUN position and check it?

Yeah, pull the rotor off and turn it upside down. Next to each screw hole you'll see either a small male square, or a small male circle. You'll see the circle and square holes near the weights on the dizzy. Make sure they're indexed correctly on the dizzy. It's likely not the problem, but it's good to make sure it's on correctly. And you're jumping the neg. side of the coil to ground, and the black meter wire to ground? Yep, it should be a half hour job. I'll check back later, I've got errands to run. Maybe check the PN on the module against Pertronix's list.

on my igniteII,I can see the magnets in the tape thats what I lined up with the rotor pointing to #1 I used another napa rotor and had bad luck till I put the pertronix one back on also had trouble one time when the gap was off on the hall cell...it came with a .030 piece of plastic I reset it and its been fine recheck it when I change caps,still orignal rotor so maybe check the gap on the hall cell and look for the magnets to line it up for #1 pug termenal on the cap looks to be chivy guts for a mopar dist I think I will stay with the stock dizzy and ign II and 40,000 volt flame thrower coil been 14 yrs and have not had a prob out of it on 4 cars now...

could be defective,missing the magnets but you said it run,just missing on #2..correct? maybe its missing the magnet in there tape,or out of phasing/idexing does the reluctor thing with the tape come off? I been looking at one hard and this is the most I have seen/read/learned sorry its at your expense what did they say about a return for another? it looks good from the pics...but? I thought they made a billet one that looked more like the stock one or a mallory the Gm looking rotor is funny looking along with the hall cell on the back side like its 180* out have you tried turning it 180* and rewire it? never know with the GM crap...

This IS the supposed billet mopar replication. It is also kind of tall and one wire actually is so close it is REAL tight against the wiper motor. I could try indexing it, the guy at pertronix told me as long as it was pointed at no 1 it wouldn't matter. Who knows. To be honest, I don't think it's worth 260 bucks. I only paid that because I wanted to be able to change things around when I drop a different cam in down the road.
I bought it from Summit. They told me I could send it back if I were not happy, might take them up on it tonight! I will drop the old one back in and if it runs back to normal they can have it back I think.

I never worried about lining up the magnet. I'm using the Pertronix ignition on a 550HP combo and it runs fine. It probably could use a CD box, and I would have no problems using the Pertronix unit.
Have you pulled #2 spark plug to check for gap and fouling?
Try exchanging the #2 wire with one from another cylinder. You might be arcing somewhere and not see it.
I had issues with mine a while back and it turned out to be the coil. I'm currently running their 60,000v coil and haven't had any issues.

man what a bummer
does it use a stock cap on it?
must be like one of the DUI dizzy I have seen
post back how it goes for ya with the old dizzy back in there
might want to take them up on it before the time expires on the meter...its beeping now
good luck
I checked the no 2 and it was good except for the fact it is mashed under the wiper motor.... maybe thats it but I did not see any misfire etc in a dark garage. Plug looked good and it fired the timing light ok when I hooked that up to it.
It runs fine with the old disty back in it. No the cap is proprietary to the distributor. You would have to buy one from them for a replacement. Since the old one runs fine I am sending the unit back to summit. They seem to be fine with it since I did talk to Pertronix tech and we came up with nothing. Who knows, it could have been a bad mag on the tape.
Now I need to get my disty curved so it's not as much of a slow advancing bone, and do some slot welding so I can run with more advance.
Thanks all for your input.
