Solar controller shows zero and I’d like to explore. Is there generally a switch or breaker to turn it off before I fool with it? Can’t find one.

I had that exact controller on my last boat. PWM. I recall seeing 0 amps at times, with a full battery.

a. If the battery is full, solar amps may be very low. Run the battery down 1/2 and then see what happens. Even then, they will not be full rated amps, because the battery is still partially charged, the panel is not at 90 degrees to the sun, and we don't know the solar declination at your location.

b. If there is no switch, cover the panels completely with a dark towel. That will turn them off.
