I once had a short circuit of some sort following engines start in a 212 that resulted in a total loss of electrical services; lots of lights came on the CWP and then went out coupled with loss of intercom and radios. More important was that we could not now shut the engines down: the idle stops are electrically operated, as are the fuel valves that the T-Handles operate!
After shouting over the din for a bit with the P2 I managed to establish that I would try and shut them down from the outside, which fortunately is relatively straightforward if the cams are not jammed too hard against the idle stop (caused by the pilot trying hard to close the throttles). It's very odd being in a cockpit that to all intents and purposes is as if it were shutdown, but with everything turning and burning.
