BE-84 BODY ELECTRICAL SYSTEM — Cruise Control System Vacuum Switch (7M-GTE only) INSPECTION OF SWITCH INSPECT SWITCH OPERATION (a) Check that there is no continuity between terminal and body with a vacuum of 170 ± 10 mmHg (6.69 ± 0.39 in.Hg, 22.7 ± 1.3 kPa) or above. (b) Check that there is continuity between terminal and body with no vacuum. If operation is not as specified, replace the switch. Vacuum Pump (7M-GTE only) INSPECTION OF PUMP INSPECT VACUUM PUMP OPERATION (a) Connect a vacuum gauge to the ACT side of the pump. (b) Connect the positive (+) lead from the battery to terminal 1 and the negative (—) lead to terminal 2. (c) Check that there is the vacuum of 200 mmHg (7.87 in.Hg, 26.7 kPa) or above. If operation is not as specified, replace the pump. Speed Sensor INSPECTION OF SWITCH INSPECT SENSOR CONTINUITY Check that there is continuity between A and B four times per each revolution of the shaft. If continuity is not as specified, replace the sensor.
