8-pin OCR System
With the key switch in the RUN position, the A1 terminal sends power to:
• The afterfire solenoid
• The OCR module "a1 pwr" terminal
• The headlights
This is similar to the 7-pin OCR system except the headlights are powered by the A1 terminal of the key switch
and the alternator bypasses the key switch to charge the battery. See Figure 7.23.
