it is certainly posisble, Boscoe has posted of this many times.

the buzzer is easily heard by pulling the safety lanyard while running!

or - before the engine is started: it will sound once you begin to "crank"


I think the water-in-fuel is easiest to test, if you so wish
since the engine does not need to be running to activate the alarm
disconnect the bowl sensor
use a piece of wire to "short" the contacts on the engine harness side

the over-temp and oil warnings can be somewhat model specific and a bit more involved

lets see what Boscoe says for your model....
