A high power pump (the mechanic said it is a 0.75HP induction motor) is mounted on the old well using those huge bolts driven through the stone. During the recent rains the grounds were water-logged, and the well overflowed too. There is now a layer of silt a few millimeters thick at the base of the pump. There are also signs the water may have even reached the axle of the pump.
There has been little sunshine during the week since the device was waterlogged. I'm sure there was some ingress of water during this incident. Understandably I'm loath to apply power to the device, as this may potentially burn the coil, blow the kit-kat et cetera.
I've applied an analog multi-meter to the supply terminals - it shows 0 resistance. The multimeter needle does not budge when the probe is connected between the supply terminals and the body. This is pretty rudimentary testing though ...
How do I determine whether the pump is safe to use? It would also be good to be able to determine whether the water within has evaporated.
p.s. The linked image is merely a rough simulacrum of what is mounted - not an exact replica.
