[Kenwood] TS-440S - Un locked Antenna tuner / installation

[Ziv Amit]

Hi 

 

I got a used antenna tuner which seller promised is in a working
condition (he still agree for full refund) and installed it in my
TS-440S. the problem is that the tuner do not lock because can't "see" a
reasonable SWR. When I bypass the tuner all work fine and SWR is 1:1 (I
am using a dummy load)

All connections/wire where checked and assembly was according to Manuel
instruction.

 

Any idea what could be the problem??

 

Thanks - Ziv 4Z9GAB
