CONTINUITY READINGS FOR SWITCH CARD & HARNESS

Model 3801

The following is a list of checks that should be made on the switch card and harness assembly before

replacing the switch card or wiring harness. These checks are to be done with wiring harness

REMOVED from the printed circuit board.

1. ON-OFF SWITCH

A. With the switch in the “ON” position, continuity should be indicated between the yellow

terminal on the 10 pin connector to the orange terminal on the 10 pin connector.

B. With the switch in the “OFF” position, no continuity should be indicated between the yellow

terminal on the 10 pin connector to the orange terminal on the 10 pin connector.

C. With the switch in the “OFF” position, continuity should be indicated between the red

terminal on the 10 pin connector to the orange terminal on the 10 pin connector.

D. With the switch in the “ON” position, no continuity should be indicated between the red

terminal on the 10 pin connector to the orange terminal on the 10 pin connector.

2. AES FUNCTION SWITCH

A. With the AES function switch manually depressed, continuity should be indicated between

the blue terminal on the 7 pin connector to the black terminal on the 7 pin connector.

B. With the AES function switch NOT depressed, no continuity should be indicated between

the blue terminal on the 7 pin connector to the black terminal on the 7 pin connector.

3. AES FUNCTION LAMP

A. Measure resistance between the brown terminal on the 10 pin connector to the brown

terminal on the 7 pin connector. The proper resistance is approximately 65,000 OHMS.

4. AC/GAS FUNCTION SWITCH

A. With the AC/GAS function switch manually depressed, continuity should be indicated

between the blue terminal on the 10 pin connector to the orange terminal on the 10 pin

connector.

B. With the AC/GAS function switch NOT depressed, no continuity should be indicated
