When my KAT500 started acting strange I opened it up. There are two
thick, green insulated wires that cross each other on the PCB, and the
top one had sagged down and got close enough to the bottom one that it
had arced through the insulation. I'm guessing I had a less than
optimal match!
Thought I would report the solution, tried a different power supply to the
tuner.that was it.

I leave the KAT500 on 24/7, several years of perfect operation.
Today I sent the usual 15 watts tune carrier on 75 meters the tuner started
cycling
all lights on and off. Turned the tune carrier off but the tuner continued
to cycle.
Tuner will only turn off by removing power. Plug power back in
