Hey guys couple questions:

Given my lack of expertise with points I decided to change out my distributor for the new MSD ready to run HEI (8529). I bought the kit which basically comes with a coil, wires, distributor and wire seperators. It has made a tremendous differance and fairly easy. I have a couple questions for the experts though:

1. Is there any sort of resistor required? I remember reading something somewhere but I believe that might have been on a different MSD version whereby you had to install an ignition box as well (not the ready to run version)??

2. Is there anything I need to be concerned with on my generator/alternator? Again, I seem to remmeber reading something about using either a gen or alt with an MSD (or other aftermarket) system or resistor?

3. (Somewhat unrelated), is there a differance in an alternator vs generator? If so, what should I be using? A problem I'm having is that I believe I have an alternator (which checked out fine at NAPA, test bench) but I have a light on in the car that indicates the GEN is not working (and it really isn't charging the batt). Any thoughts??

As info, rebuilt "67" 425 put in a "65" F-85 Cutlass. I'm using AC 45S plugs gapped at .053 (some articles said .045 to as high as .060 - picked the middle) and recurved the distributor with a medium and light spring set up which seems to work good. I've got hesitation out off the start but awesome power from about 1200 RPMS on...... still working out the carb and timing settings/recurve though.

By the way, on the alternator I did check all connections and ran a seperate groud wire from the ground post on the alternator. I also made sure the belt was tight.
