Subject: [FlyRotary] Spiral core
wires
I have 8mm spiro pro blue silicon plug wires
from my Jeff rose elec ignition setup which isn't being used. I will be
using a msd-6a ig plus 2 Chrysler igs for trailing. can I run
these wires? I will have to cut them to length and put one end on [other
already installed]. do the different powered ignitions need different
wires? kevin [I'll bet Lynn knows the
answer!]
If those are inductive spiral monel wires,
then they are required for the MSD to keep the electronics alive, and on the
stock amplifiers probably won't hurt a thing, as those were run with the
ghastly carbon dust wires.
Also needed if you want to hear anything on
the radios.
Keep the MSD powered wires dressed away from
ground and secondary wires for the trailing plugs. The excess energy can burn
through even fat silicone wires.
I love my MSDs.
The MSD will fire the coil(s) once when you
turn it on, and once when you turn it off.
This is not your Fathers ignition
system. (The Kettering field collapse system)
One day I was warming the race car and decided
to tension the oil pump belt at the same time.
The last thing I remebered was a 2 inch bright
blue arc leaving the back end of a silicone plug boot and lighting up my Timex
with the Twistoflex band. If you look real close you can see that
Twistoflex imprint on my wrist today.
If you have any Stents anywhere or a
Pacemaker. Never get near a MSD. Those things can leave you sitting on the
ground trying to remember your name. Hire a person who is already a bit
on the dull side to move wires around for you.
The MSD puts 450 to 500 volts into the coil
primary winding. Not 12 volts. So, don't get between the MSD and the coil
either.
The MSD consumes one amp per thousand RPM.
Some coils will not survive the MSD. There is a list of suitable coils on the
MSD web page. Coils with internal resistors have amazingly short
lives.
On the other hand the MSD will light the spark
plug, not matter what.
I run my sensor wires (Crank trigger
distributor pick up wires or whatever you might use) through dash 4 Teflon
lined braided stainless hose with the braid grounded at each end. This keeps
noise out of the trigger circuit, and helps prevent cross fire. Keep primary
wires away from secondary wires.
Never touch a secondary wire if the engine is
running or the ignition system is powered up.
Never power up or shut down the MSD with no
spark plugs hooked to the coil wires and grounded. It can destroy itself that
way.
I love My MSD-6ALs.
