Aircraft
While at cruise at FL410 we lost the right generator. I pulled out the QRH and began running the generator failure checklist. When we got the generator to reset; we had a CUR Limiter [current limiter] light and a Mach Trim light. We had initially declared an emergency but when we were able to reset the generator; we requested a diversion to a nearby airport for a precautionary landing. Approximately 40 miles out we received an ELEC amber message. At that point we were on Battery power and declared an emergency. When we landed; the right engine was turned off first and we had power. When the left was shut down; we lost all ship's power.
A Learjet crew diverted to a nearby airport utilizing battery power only when they suffered an otherwise complete loss of electrical power.
