Occam's Razor. aka, learn from my mistakes.

 

I was having a bit of trouble getting the wires to stay in the rectifier plug last night, the connectors kept getting pushed out when I tried to insert the plug. I carefully opened the connectors up with a small screw driver, but didn't want to go too far and have too loose a connection. Good time to walk away for the night. 

 

I called Jim this morning and expressed my hate of fast-on/never-off connectors.

Jim: Did you put them in the correct way? Which side is the round part on?

Me: Yes, with the round side to the left.

Jim: Wrong. Look inside and you'll see the ridge the little tab hooks into.Turn them around call me back.

Got back to my hangar this afternoon, pulled them all out, (ok, they pretty much fell out), looked inside the connector with my borescope. Shit.

 

Reinstalled them, and *click*. Perfect fit, and the plug went in on the first try.

 

sigh.... 

 

Me: You were right. 

Jim: Ask me how I know.

 

This is how they should look. Flat part left, round part right. 

 

 Better to find out now than force something and have it fail later because it was improperly installed.
