I'm on an ILS approach going through my GUMP and when I switch my gear down nothing happens. I cycle the switch two more times...nothing! Start troubleshooting and I see the breaker popped. I do a go around, push the breaker, cycle the gear switch one more time and hear the gear down noise. The green light beneath the switch is still off, I check the floor light and it's green. Not trusting I go around again and call the FBO asking for someone to check my belly. They see three wheels, I land safely!
What can possibly be? I left the Mooney at the shop...
