Okay, For the past month I have been experimenting with the 90's mopar electronic ignition and a petronix and coil in my stock distributor and a newer mallory built mopar distributor and I have to be frank, the petronix revs up so much quicker than the other two elect. setups! I do have the ballast bypassed on the petronix and I have the orange box with a .8 resistor for the other elct. setups. But with the petronix ignition the timing marks seems to jump around 2-3 degrees with my dial back timing light and it did annoy me. Can anyone explain to me why this is? Thanks, Dave!

#1, I had it for a little over 3 years and just recent I decided to try it out. What was weird was when i installed it a few weeks ago I used a Mallory high perf. coil for points and the timing marks didn't jump around. Then when I put on the petronix coil that is when the marks started bouncing around.

you have the ignitorII correct?

does it have a fixed airgap?

I have bumped mine when R&R the dist and had issues till i reset the gap at .030

my pertronix in my mallory duel point dist has a fixed airgap.

just thinking out loud.

Then the problem here is the coil , pertronics coils now are off shore junk. Paint the mallory coil black and run it .

Funny as many say the orange box is no good but mine has worked flawless since 2000 when I first put it on my boys Dart. I now run it on my 63 with an Acell coil. When we took it off his car and put MSD on it it did not sound any different and started the same. It also did not go any faster with the MSD. Sorry to hear so many have had trouble with them. Mine never misses a beat and the timing is right on all the time. Good enough for 6500 RPM and 10 second et's. Ron

Put a timimg light on it and tell us what the timing is at 3500 , 4000 , 4500 , 5000 , 5500 ...

I'll say this much , back around 1984 I put an Accel dual point race distributor on my dads duster with a 340 , switched it to mopar electronic after my brother kept leaving the ignition on and burning out points while he was PARKING in the car. The car ran so much better and sounded stronger with the Dual point than it did wit hthe orange box.

Comparing an orange box from 13 plus years ago to something current is not an apples to apples comparison if the old ones do not pull timing out like the current ones do.

I have looked at my timing up to 5000 rpm and it holds good as it does not take timing out. Like I said my boys car ran just as good with the orange box on his car as it did with MSD ign. Yes it is 13 years old but it is still an orange box. Maybe they were better back then as it seems most who have problems have bought their orange boxes within the last five years. I have also never had a ballast go bad on me but yet I always hear about everyone having to replace a ballast resister. Maybe I am just a lucky one John ? Ron

Maybe you are ?


All I know is the orange box that came with my 2005 crate hemi pulls out timing above 4000 rpm.

Could you please explain what pulling out timing means?

instead of just opening the coil primary circuit when triggered by the dist coil pickup it improperly electronically delays that precise moment at higher RPM's which retards the timing (kinda like a dialback timing light does). An ECU is only supposed to open/close that circuit when triggered by the dist but evidently something is electronically wonky in some of the newer orange boxes causing it to do something (delaying the opening of that wire) that it should not be doing

Got it!

Is there any way short of checking the timing at 5500
to identify bad orange boxes?

We purchased ours quite a while ago and haven't installed yet,
I would like to avoid replacing after the fact is discovered.

I still have the conversion pack box, but can't see any date on it.

The part# is 23690428, is that any clue?

Thanks, Joe

It's not necessarily BAD , it's working as designed

The easiest way to know if it's good or bad is to just ASSuME it pulls timing and use something else.
