Hi Eric,
     I learned one thing today, and I suspect You will too. For me it's that 
a 76 TR6 had electronic Ignition. I thought my 75 was the same as a 76. That 
is that it had a Points, Condensor, and Ballasted Ignition system. I think 
what Randall was refering to was having a 6 Volt Coil running on 12 Volts. 
I don't claim to know the effect on the Pertronix module, but I think it's 
possible to damage it from such a mistake.
    The Ballast is inline in the wiring from the Ignition Switch on my 75 
TR6.
