Took me 3 hours to chase down a bad pin in a cannon plug today
Kept reading open on a fuel quantity circuit and I swore it was the LRU until I pulled the connector and found one pushed pin. Ohm check pin to pin showed 0.2 ohms the whole time but it wouldn't hold under a wiggle, classic intermittent. Anybody got a trick for spotting backed out pins without pulling the whole run apart?
