I had the infamous relay 109 failure, I decided to crack it open and see what was up. It is a nice solid relay with good components, the flaw is a weak (cold) solder joint on one of the contact points. You can just resolder the points, and it is a great relay.

Amazing how a simple little solder point can shut down the whole machine.

That's awesome. I'll have to remember the fix and throw my butane soldering iron in my glove box. When I was an Army pilot, I carried my butane soldering iron with me everytime I flew. I saved us several times repairing broken connectors.
