Don--
My comment was about a Mallory Unilite system, not a points system. If you
go to the Mr. Gasket/Mallory/Unilite site
(_http://go.mrgasket.com/pdf/Unilite_Wiring.pd)_
(http://go.mrgasket.com/pdf/Unilite_Wiring.pd)) you'll find the
following caveat:
"Before installing the UNILITE. Distributor, make sure that your vehicle is
equipped with an ignition ballast resistor (or loom resistance wire) in the
wire between the ignition switch and the coil (+) terminal. Check a service
manual for your vehicle to locate the ignition ballast resistor (or loom
resistance wire). If your vehicle is not equipped with an ignition ballast
resistor,
install a Mallory Ignition Ballast Resistor Part No. 700 in the wire between
the ignition switch and the coil (+) terminal. Failure to use an ignition
ballast resistor will eventually destroy the UNILITE. Ignition Module."
The idea is to bypass the resistor and provide full voltage on startup, then
when the switch is released the feed will come through the resistor and the
voltage will be lowered to something less than nominal 12VDC.
The resistors are only a few bucks whereas the modules are considerably
more. I'm sure that Mallory would be happy to sell modules rather than
resistors....

Certain coils are designed for specific applications, and the differences
are in the resistance values of the windings within the coil and the internal
design. I used a MSD Blaster on my Mallory dual point but had to use a 0.8
Ohm ballast resistor to keep it from overheating. I ended up changing back
to the Lucas sports coil because it performed better and has the ballast
resistor internally. Most of the electronic ignition manufactures will list
what
coil to use and I would follow their recommendation.
