ATA 80

Starter Sequence Troubleshooting


1. Select voltmeter in cockpit to Generator position

2. Press and hold the ammeter/voltmeter and press the start button to read the start buss volts.

a) If you receive voltage on the meter this tells you if the starter is receiving voltage and the continuity is correct-(starter is getting power but not turning, brushes, bearings worn etc.)

b) If no voltage is present, than starter is probably OK. Starter is not getting power (RCR, SR-1 etc.)

3. Depress and hold the Start Button in.

4. Bring Throttle out of idle cut-off.

a) If ignition light comes on, then the power is good thru the GCU and SR, or the GSC may be bad.

b) If opposite buss-tie opens and buss goes dead then ASR pulled.

c) Release start button.If ignition light stays on when start switch is released, then the SR is good.
