I have six NOS single ballast resistors 2275590 These are the 0.6-0.5 ohms when hot. They are used on allot of points cars. Asking 18 shipped lower 48.

I believe this is the number used in the original electronic ignition conversion kits, yes?
I'd like to get back to the "correct" ballast as well as a corresponding coil.
Can you hook a fella up with both, sir?

Probably give me the year, and motor. If you have it the distributor number would be great.

1968 440, Mopar electronic distributor, 4 pin ecu. Has electronic regulator retrofitted as well.
If I recall correctly, the same coil was for either points or electronic, correct?
Also IIRC the points ballast was rated 0.55ohm and the one supplied in the conversion kits
was rated 0.8ohm?

Depends which ECU you got with it see the charts. Now if it is a orange box that says "replaces xxxxxxx" can be anything it was out sourced. The dual was .5/1.2 ohm the chart says .5.5 it is wrong.

Some one added that they did not have them untill 1972 except a few 340's in 71.

Mopar electronic ignition sorry.
Yes, I'm well aware; means nothing in my case, however.
Are you actually reading what I've been posting?
I'll try one last time...
My '68 GTX had the ignition system replaced by the previous owner with a factory setup from an
early 70's 440 electronic ignition. Wiring, ballast, distributor, voltage regulator - the whole bit.
It has a dual ballast included in all that, but only needs the single one (other leg was never used).

I'm currently running a Blaster II coil, older MP orange box and a ballast of around 0.4ohm.
I have the original Chrysler distributor from the swap, along with a new one (A1/Cordone I believe)
and an MP one that I can swap out as needed.
The coil is showing signs of leaking around the crown, so it's gotta go.

So....
The question remains - is the stock coil in the original factory electronic ignition of the day the same one
as the stock coil in the late 60's points-style ignitions?
Are the stock ballasts the same as well?

Thru 1974 , the same coil was used , Prestolite #2444242/2495 531 - So yes the electronic ignition used the same coil as the points systems

Do you need the coil specs ?
Primary - 1.6 to 1.79 Ohms
Secondary - 9400 to 11700 Ohms

After 1974 ? Have not looked for part numbers

The Ballast Resistor like mentioned went to an Dual Ballast design with the electronic ignition
The Factory #3656 199 Dual Ballast Resistor 1972 - 1974 used the same OHM Value on the Primary Coil Positive side as the points system 0.5 Ohms to 0.6 Ohms
Auxiliary Side 4.75 Ohms to 5.75 Ohms

Got ya thought the regulator was retrofitted. Coil as stated above ,4 ohm ballast is a bit low but fine. here is the factory ballast numbers depending on the ecu part number it should help.
