Component Test Procedures 2-9

Gate Interface Resistance

Measure the gate interface resistance for each output power transistor. The

resistance from each gate and collector pin to the branch emitter pin should

be about 500 ohms. If any of the gate interfaces fails this test, replace the

appropriate (left or right) Output Power Module per Power Structure.
