Service Manual

Test 3 – Output diodes

• Check the four diodes in the bridge with an ohmmeter in diode test mode.
• For each diode, the value should be “open” (very high resistance) with the meter leads in one direction and 0.1

V to 1.0 V with the meter leads reversed.

- A diode is shorted if the value is less than 0.1 V. Replace the bridge.
- A diode is open if the value is greater than 1.0 V in both directions. Replace the bridge.

Note: In each case, common (black) should be on 3.
