Don,
I made some diode voltage checks and here is what is got:
Anode Cathode
D9 ref: 1.41 (13.6 actual) ref: 13.8 (13.3 actual)
D10 ref 0.0 (0 actual) ref: 14.1 (13.6 actual)
Anode
D11 RX 0-10w ref 14.1 (actual: seem floating in mv range)
RX 11-110w ref 1.5 (actual: seems floating in mv range)
D12 RX 0-10w ref 14.1 (actual: 1.4V)
RX 11-110w ref 1.5 (actual: 3.6V)
D13 RX 0-10w ref 14.1 (actual: 13.6V
RX 11-110w ref 1.5 (actual: 1.4V)
D14 RX 0-10w ref 14.1 (actual: 13.6V)
RX 11-110w ref 1.5 (actual: 1.4V)
Visual check doesn't show anything wrong. Any thoughts on what could be
going on here?
Thanks for the help
Sam
