Took an unexpected "lightning strike" in the Dash early one morning enroute BUF-PIT. This was back in the day when the main bus tie was only used for battery starting the #1 engine. Even without the mains tied, we lost both DC gens, and the left main bus. Losing the left main bus takes out things like the #1 DADC (which feeds the CA Altimeter), RNAV, Wx Radar, TCAS, GPWS, illuminates a whole bunch of lights on the caution panel, and kills half of the lighting in the passenger cabin. Had to quickly transfer flying duties to the FO, call ATC to advise them of our "situation", and figure out how to use the red book to put the airplane back together.
I didn't want to deal with the essential power issues listed in the Dual DC Gen Failure checklist, so I stopped that checklist and chose not to turn off the battery switches. I treated it like a single DC gen failure instead, cycled one of the DC Gen switches at a time, and got one of the two DC gens back online. With an operating DC gen, the left main bus came back online too.
Contract MX in PIT couldn't find any exterior damage to the aircraft. They MEL'd the one DC Gen that would not reset, and sent us on our way to MDT and then on to PHL. An Air Whiskey crew was deadheading on our next flight out of PHL, and the pilots stopped up front to see how 1980's Bombardier/DeHavilland technology of a Dash 8-100 compares to the 1990's Bombardier/Canadair technology of the CRJ. When discussing the ruggedness and durability of the Dash, I mentioned to the Air Whiskey crew that "we had a lighning strike earlier today, and we're still on-time!"
