Some Ideas
- To check for polarity of the ammeter wiring: just disconnect the coil output wire to the distributor, so the engine won't start. Then turn the engine over. You should see a pretty significant negative discharge during that time.
- Was everything normal before you made the latest round of modifications? If so you may want to consider the old rule "check the last thing you did." You may have inadvertently disconnected a wire or mis-wired.
- I'm not aware of the need to polarize an alternator. I never have.
