Jake brake failure

John, that guy is yanking your chain, the new engines most have a 3 speed Jake brake, and Volvo has their own system similar to the Jake. 
The exhaust brake will cause problems sometimes had 3306 Cat that exhaust brake system would break the compression ring on it   good luck

Hey, hey, glad to hear you got it fixed!

Side note for all RE Jakes:
Living in CO, I wouldn't dream of owning a coach w/o Jakes.  But I use them all the time on the flats, too... slowing down for curves, speed zones, red lights, etc. Consequently, there's hardly any wear on my rear service brake linings I put in about 10k miles ago. They didn't even need adjusting when I was under there a few weeks back.

Once adjusted and in proper running order, Jakes should give you MANY miles of worry and maintenance-free (and safe) driving. And if you get out of your depth or comfort-zone with troubleshooting and maintenance, I suspect most HD diesel shops can help service them, since they're so common in the trucking industry.

My $0.02,

This is one setup I would love to see how it it wired no way should he have power to the Jake's at idle if wired according to Jake and a broke wire with a bad solenoid under the valve cover make a Jake engage    good luck

What happened when the wire broke and shorted out it also damaged the control switch, the one that the wires come off to go to each bank. This wouldn't allow the jakes to come completely off. I was still having a little trouble this morning and took it to Cullen DD in Cranbrook. They pulled both covers off and some time previously two solenoids were replaced with 12 volt ones. We replaced the switch and all four solenoids with 24 volt ones. Hats off to Cullen they sent a mechanic (not a technician) out to the parking lot and he diagnosed the problem in a couple of minutes. Pulled me into the shop and had me going in less than an hour.
And I agree unless I was a flatlander I wouldn't leave home without my old friend Jake... Nothing worse than a sign that says 7% grade for 10 miles...

Some form of engine brake is pretty much standard equipment on all your new big trucks. They are integrated from the drawing board these days.

happy coaching!
