Flying out of Reagan one night in a Lear Jet in a 30 degree bank to clear the prohibited area had the voltmeter peg out as the left generator went off line. I shut off the right generator and the left one picked up the load with normal voltage. Later I looked through our checklist and found no procedure for our fault. The overvoltage on the right generator kicked off the good left generator. We would have probably fried everything if we had not done what we did. We had some high level Hollywood celebs on board so it would have been interesting if we had followed the checklist.
