Barrett 950 - Transceiver will Not Power up

BARRETT 900 SERIES TRANSCEIVERS
Plug the transceiver into a 13.8 VDC power supply, switch the transceiver on, if the transceiver is totally
inactive:-
- Check voltage on the input power cable on the PA PCB is between 11.8 VDC and 14.5 VDC.
- If using a remote control head, check the cable between the head and the main body of the
transceiver
- Check the 26 way cable between the PA and the RF/Audio PCB's.
- Check the 14 way cable between the Front Panel and the RF/Audio PCB's.
- Check the 50 way connectors are mated between the RF/Audio and the microprocessor
PCB.
- Check the Cathode of D1 on the PA PCB is > 10 V when the transceiver is off and low when it
is switched on.
- If a single relay click is audible on switch on but the transceiver is otherwise inactive the 3.15A
fuse on the PA PCB is probably blown. Check for obvious damage or short circuits prior to
replacement.
- Check all the voltages as indicated in the table next page.
