Test 20: Entrance/Exit Light Circuit (5 Minute Delay)

Using Harness Adapter (210 589 01 63 00), connect Breakout Box (129 589 00 21 00) to combination control module. Measure voltage between terminals No. 27 and 75 at breakout box. Open any door. Battery voltage should exist for approximately 5 minutes, then voltage should drop below one volt. If voltage is as specified, entrance/exit light 5 minute delay is okay at this time. If voltage is not as specified, perform TEST 17 . If no problem was found during TEST 17, replace combination control module.
