Here's one for electrical gurus. Help.

It is real simple to check pickup wiring polarity.
1. Check ignition timing at idle with light, assuming 10 deg BTDC.
2. Set the engine crank to 10 deg BTDC.
3. Pop the distributor cap, check were a reluctor tooth is in relation to pickup nub. They should nearly line up, the tooth just a bit on the way past center of nub
4. If the pickup nub is between reluctor teeth, the wiring is wrong in polarity.
