[6pack] Pertronix failure

[John Mitchell]

    I had my Pertronix unit on my TR6 fail this evening.  I've had it 
less than a year.  Luckily I had a backup unit in the boot.  A quick 
switch and all was well.  At home I checked the wires going into the 
sensor for continuity and both were solid all the way.  The only 
difference in wiring, was that I had the red lead connected to the fuse 
box and the black lead to the negative side of the coil.  I did it that 
way to hide the extra wire and make it look original.  Could this have 
effected the longevity of the unit?  Thanks for any insights.   John
