IIRC there is a ltitle electronics in these
cabkits, something like a
linear voltae regualtor to provide the power for the transceiver. Is
it possible that this has failed. Have yuo measured the votlage
ebtween the transceiver power ins on the AUI connector using both the
good and bad cabkits (with the machine powered up, of course)?
Unless I'm grossly mistaken, the only thing that's even close to being
electronics on the cab kit is a fuse. It is otherwise
just wires
(inasmuch as a
fuse is not a wire).
Indeed, there are no active components, just a fuse. The kit is entirely
passive.
My money is on a bad receptacle pin socket. Have you
tried plugging in an
unpopulated DA15 plug (solder cup type) and checking the continuity with
that?

This is the avenue I am going to pursue. This cab kit used to work, but it
has stopped working. I will just have to find a DA15 plug to test with.
