Our Tech Tip this week is from Carl Gwyn
I have been using the Pertronix Ignitor Electronic Ignition for a few years now
in my '68 MGB. I think that they are a great little unit; however, when
installing care must be taken to make sure that there is enough play in the
wires inside the distributer so that the vacuum advance is not hindered.
Having been careful to do this, unfortunately I had a little too much wire and
the insulation on one of them got "nipped" upon putting the distributor cap
back on.J This cause the unit to short out.
To avoid this in the future, I installed a new unit and placed the wires around
the inside of the distributor. Then with a felt tip pen, I made a mark outside
of the grommet (which may need to be trimmed some depending on the distributor
cap for a good fit - jz) where the wires exit the distributor. Now the wires
can be pulled through the grommet so they move well away from the side of the
distributor for installation of the cap. Once the cap is in place, the wires
are pushed back into the distributor so the mark lines up once again with the
grommet. I tried this a few times and each time I opened the distributor, the
wires were nestled comfortable against the side of the distributor with the
maximum amount of clearance for the motion of the advancing mechanism.
