Reply to "No spark"

Hello, the issue was voltage drop below 10.2 volts at the trigger wire when cranking on the starter causing the 6AL to not operate but, when spinning the distributor by hand out of the engine with the key in the run position sparked like a MOFO to the plugs. Running the 30 amp circuit to the dual cooling fans, A/C condenser, blower motor and lights was to much draw. When I install my new non electronic distributor today I will check the out put on my alternator. This was a tough nut to crack and hopefully this will help someone in the future because I thought as  well as everyone else this was a loose wire, bad connection or a grounding issue, I learn something new every day. I have a brand new 6AL, 8560 MSD ( I think that is the model #) distributor with 8MM wires (like new) and a 6A box with 1,900 miles on it for sale at a very reasonable price if anybody is interested.
