Vent: Chasing a bad ground on a King KX 165 took me 6 hours when it should have been 20 minutes
I spent an entire Saturday tracing a faulty ground wire on a Cessna 172 that turned out to be a corroded connector hidden behind a firewall blanket, and I still can't believe it took that long to spot.

Started with the firewall ground block and saved myself three hours.

...and the worst part is I spent the first hour blaming the King unit itself, like "oh this old radio finally gave up on me." Pulled the whole tray out, checked every pin, cleaned contacts twice. Then I start poking around with my multimeter and find voltage drop at the ground lug, but only when the engine's running, which is just cruel. That hidden corrosion behind the boot cowl blanket is always the culprit, always. I swear avionics gremlins specifically wait until you're 6 hours deep before they reveal themselves.
