3.8 TESTING PROCEDURES

3.8.1 Testing AMP draw for components

When checking functions of individual components, place amp clamp over black (power)
wire coming in from the generator to the CCU board. (As shown in below.)
When cross-referenced with the "AMP DRAW AND VOLTAGE CHART", the components
should show the same amp readings.

3.8.2 Testing Voltage and Hz readings:

When checking for 120 VAC at the CCU board, the probes are placed at the black wire
terminal and the white wire terminal.
When APU is running there should always be between 110 – 130 VAC present.
When APU is running the Hz reading should always be 60 +/- 2.
