[Tigers] Pertronix Ignition

[James Burruss]

On a Saturday drive, my Tiger's engine shut off instantly as if the ignition
key had been turned off.  It would not restart.  I suspected that the car's
Pertronix II ignition had died, as they have been known to do.  Mine had
been reliable for several years, although the car is not driven often any
more.  I had the car taken home on a rollback.

 

This morning, I began a series of checks.  I ruled out the ignition switch
as a possible culprit because the starter, gauges and fuel pump all worked.
I checked the wiring connections, coil resistance, voltage to the coil, and
even fuel in the carburetor; all were fine.  So I connected an induction
timing light to confirm that there was no spark - except that there was!
Then I got in the car and started it.  It ran fine.

 

Which brings me to my question for those who have experience with these
ignition systems:  Are they known to become intermittent due to heat?
Saturday was a warm day, mid-80s, the car had been driven moderately for
about 10 miles and its temperature was normal.   Needless to say, I no
longer trust this system; but I would appreciate knowledgeable comments
and/or recommendations for a replacement ignition for a stock 260.

 

Many thanks!
