Electronic Distributors From Rick Ehrenberg

I appreciate the suggestions. I am pretty sharp with some matters but electrical stuff is not one of them! I do want to learn more so that I won't just be a parts swapper when the car won't start.
To me, a talented dude diagnoses while a simpler minded dude just replaces parts until the car runs again.
Currently, I am the latter with electrical problems. I do have another alternator to swap in, a "Tuff Stuff" unit. It is supposed to charge more at all rpm ranges. For now, my voltmeter will dip below 11 volts at idle with the headlights and high beams on and pressing on the brake, turning on the A/C drops it further. Once I rev up to 2000 rpms, the gauge will come up to the 13 range. With no lights or A/C going, it holds a steady 13.8 to 14 volts at 2000 rpms.
