Obviously, Pete, you have been studying these systems for awhile. I am like
that too. I like to know everything I can so that I am at least knowledgeable
enough to keep from gettin hosed by an unscrupulous mechanic.

Thanks for all your indepth analysis. You have been a great help is dispelling
some of my fears on this motor coach.

Jake Brake or Jacob Brake is a particular brand of engine brake
manufactured and sold by Jacobs Vehicle Systems, Inc. While the term
Jake Brake technically only describes Jake Brake brand engine brakes,
it has become a genericized trademark and is often used to refer to
engine brakes or compression release engine brakes in general,
especially on large vehicles or heavy equipment. See Wikipedia for a
full entry at:
<http://en.wikipedia.org/wiki/Jake_brake>

The magnetic retarder used on some earlier BBs is similar to the
technology used for "dynamic braking" on diesel-electric railroad
locomotives. The diesel-electric locomotive is actually a diesel
generator (up to 5000 HP) that powers electric motors to drive the
engine. On down grades, the motors are electrically switched to
become generators, and the power produced is directed to very heavy
duty grids and discarded as heat. Realize that these things produce
600 amps at 600 volts and that's a _lot_ of heat! (Great for toasting
marshmallows.)
