Since I am using Delco 1-wire alternators, there is no field wire connectors to unplug...

I don't think it is the fan itself, since the 100 amp alternator was causing a misfire with the fan on or off. The smaller alternator must just make less interference at a given amp draw. FWIW, my fan runs off a relay. The power wire comes right off the alternator, through an in-line fuse, to the relay and to the fan. Those wires are not near anything else, they run to the passenger side of the car (where the alternator is).

That's my thinking anyway.

Is MIKESDUSTER having MSD misfire problems? I will look for his post.
