8.
Remove the cable from connector XP on the pulse transformer circuit
board.
9.
Check the gate cathode junction of the field SCR/dual diode module.
With the digital multimeter set to “diode test” measure the resistance
across the modules (lead orientation is not critical). See
If a low resistance is detected, replace the SCR/dual diode module.
