Sunday when I had my little overheat issue, I also noticed my electric choke was inop. I only posted on the overheat, thinking "only one thing at a time." lol

The motor starts fine without choking, but I want to fix it. And as it's not time critical, and not imperative to normal operation, I've got the time to look at it myself.

So looking at the wiring diargram...I'm a bit lost. I'm a helicopter mechanic by trade and work on turbines for a living, but I'm not a marine engine guy, or even really a piston engine guy. Where do I start to look for this? I pulled the switch to check wiring connections and look for corrosion, but it's a sealed unit. Has anyone had similar issues with the ignition/choke switch going bad over winter? (Again, stored in a heated garage.)

So moving on from the switch to the other end, I get to thinking, "how do you choke a fuel injected engine?" When you hit choke, and hear it on the engine "choking" what's actually moving and activating? I looked on the wiring diagram, and don't see any kind of choke relay or anything to that effect. Where do I look? Can someone point me in the right direction?
