Remove the magnetic collar from the distributor shaft, and make sure all 6
magnets are present. If you rotate a small nail around the outside diameter
of the collar you should feel six distinct areas where magnetism is present.
If you do not count a total of six magnets, you are either missing a magnet
in the collar or it the magnet has no magnetism. Call Pertronix and ask for
a new collar. Even if they are all present, call Pertronix and have them
send you a new collar. Why? Because you may have one or more magnets which
are not of the proper polarity. I ran a Pertronix when my previous employer
wanted to stock them, I had four magnets of the proper polarity and two
which were not. My TR6 ran horrible. Feeling it was an isolated case we
sold them for about 6 months, in which we had about 30 units returned to us
for problems that neither we or Pertronix could resolve.
My personal opinion of Pertronix units is that they are very poor in
quality. Not only do they have problems with the magnets, but in a
customer's vehicle the glue which holds the cover on the collar to stop the
magnets from coming out, came unglued and magnets were lost. They typically
are for people who do not want to rebuild their distributors with new
bushings. A distributor with no shaft wobble and properly gapped points
will give you every bit of performance and smoothness that the Pertronix
does. With proper maintenance you will experience reliability on par with
an electronic ignition, or if you get a bad Pertronix unit, you will
experience better reliability with the stock components.
Pertronix usually does not mind sending out replacement collars, they're
cheap to produce. They rarely ever sent out replacement hall effect sensor
modules to our customers when we suspected that was the problem. Pertronix
has or had the opinion that the sensor modules are almost indestructible and
never fail.
These Pertronix units belong in a JC Whitney catalogue and that is about the
only place... check the MG list archives for some more horror stories.
