I have a 2000 CC Allure. It has an exhaust brake but did not seem to be operational last trip. I have about 4.7 volts running thru the switch so not sure if that is correct.
I have the wiring diagrams. The diagram points you to a "FRONT RUN BOARD" but I have not been able to locate where that is.
Any Idea where this lives?
Any insights as to what may be the issue???

Thanks for any advice and input you can provide.

Sincerely,

On my rig the Front Run Board is the series of Chassis Fuses and Relays located in the forward basement driver side compartment.

Your rig might be different location.

I checked and did not locate the front run Board in the Driver side front bay compartment. Does anyone have a clue as to where the "FRONT RUN BOARD" may exist on a 2000 CC Allure?

I had an issue with my exhaust brake not working also. If I remember I turned down the idle with the swit ch on the left side of drivers seat, blue switch. I didn't want it pulling so hard when stopped. Well I think when the idle was below 600 or 700 the exhause brake stopped working. Have you adjusted the idle speed lately? Does the light come on on the dash?

I also have had issues with my Jake Brake and looked for the brake relay shown on electrical drawings. Front running board on my rig is everything behind the dash accessed behind the removable cabinet on the center of the dash. Lots of things hidden behind there. I created a diagram (attached) and put it in the cabinet. Nothing is identified so I had to reverse engineer what the function is by wire numbers and the wire number list in my chassis documentation.

The compartment under the driver is called the steering bay or electrical bay.

I do not have a correct drawing for the exhaust brake wiring. My drawing ends a few hundred coaches prior to mine.

The Jacobs Brake is interconnected with the engine ECM and transmission controller making the wiring difficult to trace. The switch alone has 7 wires going to it and is interconnected with the headlights. I replaced the switch and ended up running a duplex cable to the engine from that switch to break the circuit to the rear Jake. I had both Jake units going regardless of which switch position and could not figure out a better solution. Now I have the two stage function for the first time.

Ha here is what I found when I had trouble with mine...

2000 Intrigue

When I had a problem I called pacbreak and they helped me diagnose the problem. In my case they said one of 2 parts were probably causing it. The solenoid. I forget the other possibility but both were about $100.

They thought the higher probability was the solenoid . Turns out they were correct.

Hey folks, I think the OP is trying to find his chassis fuse box or Front Run Board. Can you help.

If you raise the bed and inspect the piston that activates the exhaust brake, you may find, as I did, that the piston shaft is detached. Good lock us53318334

There is an exhaust brake relay in the steering bay in the Allison module, replacing that relay fixed an intermittent exhaust brake on my 2000 Intrigue.
