[T3] Coil Resistance and Heat

[Jaime Gurrola]

I ran a new SVDA Pertronix distributor with Flamethrower I yesterday 
with the FT III coil.  The coil got ridiculously hot then the car just 
stopped running after about 10 minutes of running.  The coil reached 
+250 F degrees.  The rest of the engine was at normal temps. I replaced 
the coil with the Bosch Blue coil but haven't been able to re-start it.

I measured the Bosch Blue coil resitance between the + & - terminals and 
got 4.5.  I measured the the resitance in my Pertronix Flamethorwer III 
coil and it was 1.4 ohms and the box it came in says  .32 ohms.

Have I damaged either the coil or the ignition module or both? Why did 
the coil get so hot?  How does a change in resistance affect ignition 
system?

Thanks,
