Technical Support / Re: Check engine light reset

Tom,
The ECU should shut it off if it is detecting normal operating conditions but it sometimes takes awhile. Cruise control can sometimes affect it so be sure CC is off and run engine or drive it for a few miles and see if that does it.

Technical Support / Re: Fast Idle switch Engine Brake

« Last post by David T. Richelderfer on February 20, 2026, 07:40:39 PM »

Please put your coach's year and model, and your engine in your display info.  That would allow owners with similar equipment to help.

Is your engine brake a PAC Brake or a Jake Brake?  If it's a PAC Brake, then it may need servicing - like greasing, I think is what they do.  It runs in the exhaust stream, so it requires regular maintenance.

Our coach has a two-position Jake Brake.  The rocker toggle for it has three positions; the down position to the rear is the little Jake, the center position is Jake off, and the down position to the front is the big Jake.  I believe the little Jake position uses three cylinders versus the big Jake uses six cylinders.

Our coach does not have an engine-idle-increase switch to my knowledge.  I use the cruise control and accel buttons.

Technical Support / Fast Idle switch Engine Brake

« Last post by Nicholas Soldevere on February 20, 2026, 03:22:03 PM »

Ok guys , I have another one for the Beaver Wizards here, all your help is much appreciated btw. 

My "Fast Idle" switch on the side panel does nothing. In probing it, I can only see 3.6vdc, in my mind it should be 12vdc. Is it supposed to be 3.6?   I can find no wire print related to this system. Does anyone have a wire print to it. BTW, I can go to fast idle using cruise control switch which I suppose is an alternate method.

As an aside, I was working on Engine Brake system yesterday. It has been a very INTERMITTANT system since I owned the rig. As we all know that's not good. I found where the previous owner had wired the eng brake to receive power from the brake light relay using a nice wire salvaged from an old computer power wire. Anyways, after removing the po's mess, and on test drive I found the engine now activates when removing my foot from the accelerator. I suspect this is the reason they wired it like that.

I know there are 2 stages to this engine brake, can anyone explain the differences from the switch forward position and the switch back position?

    Hey Chuck,
  Great news! I am really happy you found the issue. No power in equals no power out! Sure beats buying another Inverter/Charger. Thanks for getting back to us with the results. Some folks solve a problem and then go their merry way and the forum does not if it accomplished its purpose! Blessings, Fred

Well I’m back up and running . It looks like the inverter was replaces in 2017 . The black 120v wire was burnt and was not making connections. Pulled it out and cut it back to good wire replace the wire nut and checked all the others and replace the electrical take and all wire nuts .

Chuck,
If you have to replace the inverter, consider a Magnum Pure Sine Wave unit. I replaced my Xantrex with a MS-2012 unit after having issues with my Samsung reefer. It worked flawlessly and was easier to operate than the Xantrex unit. That said, if you are not planning on ever installing a residential reefer and are satisfied with the operation of your current electronics, a modified sine wave unit is probably sufficient and less $ than the pure sine wave unit.

It is most likely the inverter pass through, I’m going to pull the cover tomorrow and see if there is a fuse. Google says it’s not worth repairing, I’m going to be the judge of that … thanks for all the help I’ll let you know what to find

OK I am about to give up.  The last post was only partially populated and the site keeps going to the other BAC site that has nothing to do with us.  Check your resettable breakers if you have a freedom inverter, also check the manual online here.  Hopefully this will post

Chuck,

To follow up on Fred who has forgot more than I ever learned, what type/brand of inverter do you have?  My old Freedom in the BAC members only section.

Hopefully it will turn out to be something simple.
