Thanks 77, you stated that there is NO CONTROL BOX? then that is why I couldn't find it! Do you have a link to the correct Jake Brake Page?
Sounds like my problem would be the Buffer Switch and since the Adjustment hasn't been messed with I'll start by checking it. From what you stated the Buffer Switch is a normally Open or Closed Switch that is Activated by the Governor (+ 12 Volts DC to the Dash Switch, then when On +12 Volts DC to the Buffer Switch, then when Switched +12 Volts DC to the Solenoids?)

Advice as to where to get a new one?

***Quick Update***
Found what appears to be a Limit Switch with a Plunger type Assembly on the Governor. Had Detroit Slobber on it so I cleaned it with a Electrical Cleaner. I used my Volt Meter on it and have + 12 Volts DC coming into the Switch. Started the Detroit and brought up the RPM and then let off of the Throttle to try and read the Voltage when the Governor went to No Fuel but the Digital Volt Meter isn't fast enough to get a good reading so I'll need to wait until I get my Analog Meter on it.

The Rubber Boot on the Limit Switch looks to be in poor condition so I will be replacing it when I return from this run.
