I used the Troubleshooting manual that Michael Posted earlier (Thanks Michael!). Not being sure how long that Manual will be available online I posted it here under Documentation along with my hand drawn diagram ***This Manual is for the 71 and 92 Series Detroits as well as some Cummins and Caterpillars;

I think that if I have another issue with the Jake I would start at the Fuse and then go straight to removing the Valve Cover. The Operation is fairly Fast so I couldn't use my nifty Digital Meter to Check the Voltage so I had to go to my trusty Simpson 260. But better still is that you can actually see the Solenoid Pull In and then Release! The valve cover seals are rubber so they are reusable with no issues. ***The Components inside the Valve Cover are Hydraulic, but don't let that scare you because as I have been able to find out most of the Troubles with these Systems are Electric.
As 77 stated you do NOT want this Engaged when the Throttle is Depressed and I would NOT want it Engaged when at Idle. Still really easy to lift the valve cover on the passenger side of my 6V92 and watch the System Operate.
PS The Manual suggests that you Adjust the "Buffer Switch" at 100,000 miles and with only 125,000 miles I can see why.
