Hi to the group
I am working on a KPA100, page 43 manual, here the KPA is connected to
the K2 with the ribbon cable, power to the K2 but NO power connected to
the KPA100.
page 43 list a series of voltage tests ""ground to test point". my
problem is with D13. I do not get any voltage at D13 banded end. Also
U4 (MA1406) pin 8 has -28V manual calls for -5 to -25 V TP1 has
correct result, J3+lead (red) has.03V manual calls for 0V.
During the resistance tests of the KPA100, page 41, manual I also had
problems with the D13 measurement. At first I had no reading,
reheated the connections for D13, had first intermittent and after
several tries the correct resistance. When I did not get a voltage
reading at D13, I disconnected the ribbon cable between KPA and K2,
attempted again to get a resistance reading at D13. This time I could
not get a resistance reading at D13. DMM show an open circuit.
Does anyone have any suggestions?
Thanks Hank WA9QJH
