New alternator, has been tested. D terminal is getting 7.75V (exciter) 3.75V after starting. W terminal to Tachometer.
B- terminal is grounded. O+ terminal connects direct to battery isolator.
O+ measures no voltage when ignition on and no voltage after starting.
When connected direct to battery (bypass isolator) alternator works.
I have replaced isolator and still no charge.
I believe the o+ terminal has to see 12 volts to operate? Should O+ get input from other source?
