I'm installing the ignition thingy into the distributor and a new
Pertronix coil. The old coil said "use with an external resistor".
The new one has that built in. I don't see any resistor anywhere in
the engine compartment. What am I missing? Is it built into the
wiring from the ignition switch? I don't need 2 resistors.

By the way, the instructions for the new coil say it should be 1.5
ohms. It registers 1.7 and the old coil registers 2.1. Are they near
enough that I don't need to worry about the resistor?

The Pertronix needs full battery voltage to operate properly, so you
definitely need to replace the coil with a non-resister type. Then, look at
the wire attached to coil + terminal. If it is pink, it is a resistor wire,
and that too should be replaced. I think R engined cars had a Black/green
non-resistor wire to a ballast resistor and from the ballast to the coil.
On those cars you would only need to bypass the ballast.

You may have a resistance wire in the harness, not sure. If the coil
primary wire is pink and feels different than the other wires in the
harness it is likely a resistance wire, you need to run a new wire from
the ignition switch in that case.
good luck

Well, it doesn't matter right now anyway. They sent the wrong kit. It
was for the dual point distributor. Talked to the tech at the factory,
says they don't have one for the Prestolite IBP. So I can either just
put the points and condensor back in (I'm still gonna use the new coil)
or get a Delco.
I think of it as an adventure.

You should use the "Flame Thrower" coil from Pertronix along with the
distributor module.

I'm gonna...that was my original question.
I bought the super coil along with the Pertonix unit. (The Pertonix
unit that DOES NOT work with my distributor.) THAT Pertonix super coil
has the resistor built in. The instructions for that coil say you
don't need an external resistor.
On the other hand, the Prestolite coil (the one that was originally on
the car) has a notice printed on it, "use with an external resistor" I
don't see a resistor anywhere in the engine compartment so my original
question was: Is the coil resistor built into the wiring from the
ignition switch?
So it looks like I need a Delco distributor so I can get a Pertonix
unit that will work. What models used that one?

Use the new coil and most likely, your car has a "pink" wire from the
distributor to ignition switch. Replace it with a conventional wire.

Gotcha!! Thanx.
