If oil temperature

let the lubrication system cool down. After that try a restart of the engine
and check the oil pressure after starting. If the oil pressure warning light
comes up again shutdown the engine and prepare an emergency landing.
Electric failures
Before trying to
reactivate the generator search for the reason of the fault. Possible reasons
could be an airstart with a running generator (overcurrent) or an airstart
while the generator charges the battery. This mostly also causes a complete
electrical fault of the battery, essential and nonessential busses.
