Removed the valve cover off of one of the engines at school that is equipped with a Jake Brake. We ran the engine but could not get the engine brake to engage, so we disconnected the solenoids on one side of the engine that are used to activate the brake. We then placed wire leads on the solenoid and activated it manually to see the brake work first hand. It was a very useful demonstration for me as I never truly understood how the brake was activated/de-activated. This video animation caused the light bulb to finally illuminate.
