VOLTAGE TEST
Engine running, headlights & heater fan on high:
Alternator post to alternator frame = 13.5-14 volts (verifies the alternator output)
alternator post to battery (+) = 0 volts (verifies the primary + wire)
alternator frame to battery (-) = 0 volts (verifies the primary ground)
Turn off the motor, but leave the lights on.
Battery (+) to battery (-) = ~12.5 volts and holds steady. (verifies battery)


Hmm - it's stalling - so the idle adjustments may be wrong.

The basics:
The rotary engine has very low torque at idle.
More than half of the hoses, solenoids, & sensors on the motor are for idle speed control.
You need to patiently go through the idle setting procedures in the factory service manual.
I have a link to an on-line copy of the FSM in my sig.
Download & print the "fuel & emissions" section.
