So are you saying the alternator is OFF the first 20 to 30 seconds the motor is running?
You disconnected the alternator output and ran it through a ampmeter to verify no alternator output?
If true, I'll have to get my electrical diagram out and see how Ford cuts off the alternator. I assume they interrupt the exciter field voltage.
