you're welcome. If you measure with a voltmeter from coil+ (the wire that goes from ballast resistor to coil) against ground, you'd probably read 8 to 10V instead of 12 with ignition switch on.

and this is the book you want (all else is crap!)

however if you can get your hands on the book version not the CD, try to grab that. It's a lot handier than printing pages for the garage ;-)
