After half a year I planned to make a flight in my FK14B with a ROTAX ULS 100hp engine. Installed a LIFePo battery with a Silent Hektik regulator.
After applying the master switch all electrical equipment are alive.
Then I applied the starter button and after a few prop rotations all went dead.
All fuses OK including the 20A one.
What could be the problem? Starter relay?
