L7-65 wont spin now

Worked fine last week now no.

Pulls good vacuum, cools fine, tach works if you spin shaft. Motor wont start at all not even low speed start check. Checked all connections and boards for obvious damage. The 347186 board lights for Drive circut, only left one blinks rapid on start attempt and Diff pump relay clicks on and then off. I notice on my L7-55 both lights blink rapidly in start up ?? Was getting odor after 6 hr spins when i open chamber. Also what is the Beckman Drive oil spec or Beckman oil number for that thoes drives? Is it the 302411? Thanks Rudy
