Dave, I would suggest that your coil is OK and you had inadvertantly wired
your stereo through the resistance wire that serves as a ballast resistor.
(At least that is consistant with the voltage readings you get at the
coil.) Is there a different accessory lead you can tap, off the ignition
switch?

(If need be I can see if the Bentley manual diagram shows which lead to
tap, when I get home.)

Thanks for sharing your results with the List!
