Just spent 45 minutes chasing a ground fault on a Cessna 172

Turned out to be a chafed wire behind the avionics bay, lost the insulation against a sharp screw. Replaced the wire and wrapped it with harness tape, now the NAV radios come on without flickering. Anyone else find hidden chafe points in the weirdest spots?

Buddy of mine found one in a landing light wire, drove him nuts for days.

Number 47 wire in a Cessna 172 had mine chasing ghosts for three weekends.
