RE: VECTOR:TECH ESB Pot test

Thanks!!

Swapping in another AD convertor from an old boardset did the trick!

Those Imperial Walkers are dropping like flies!!

Thanks for all your help,

Hi there,

The most easy thing to check is the AD convertor, since this one is
socketed.
Look for a bigger chip on the CPU board, with 'ADC0809' printed on it.
Maybe
reseating it will fix the problem, if not, try another one since they
are cheap.
If this does not solve the problem, check if the chip select input of
the
ACD0809 is changing states regularly (in the yoke test mode) to test the
address
decoder for it. If this line is stuck, the chip is never 'looked at' by
the
processor. At last, check if the X and Y voltages from the flight yoke
are
present at the right inputs of the ADC0809.

Cya !
