[Healeys] coils

[Michael Oritt]

I have been running a Mallory Unilite distributor and an MSD Blaster coil
with power routed to the coil through a 1.5 ohm ceramic resistor in order
to lower current and protect the ignition module.
At one time I wired a bypass around the resistor to deliver full current
for starting as Mallory suggests but I found that the car starts fine with
the reduced current so eliminated the bypass wire.
