Finally have a little time to troubleshoot. No
clicking relay, just no response at all.
There is no visible damage to anything that I can
see on the little circuit board to which the power
connector is soldered. No smell of something
burned either.
I am looking at the schematic 4-32 in the Op Manual.
Any suggestions as to which device(s) is(are) most
likely to have failed, please?
Thanks! doc

assessment of the potential damage.
I sure appreciate the helpful hints from so many and
will report back to the list what I discover later in
the week.

Symptoms are no response when the power switch is
activated (the fuse is fine).
Time to pack it and ship it to TenTec? ;-(
Wait!
Let us try a more comprehensive diagnosis?
Say, can you hear the power relay clicking when you try to switch on
your Jupiter?
Regarding my circuit diagram of the 538 Jupiter, there is no reverse
polarized diode to protect the power input.
But the mains switch triggers a relay via a switching transistor. Only
when this realy is activated, the main circuits are connected to the
mains power. So you have a good chance, that you only damaged this
switching circuit, not the main transceiver circuits.
