engine brake issue

Clutch or brake switch?

 

being as how the engine brake is designed to come on with the gas pedal off. i don't think there's a clutch or brake switch involved.

 

Is the engine cold when it is doing this? The engine brake does turn on to help the engine heat up quicker unless it is turned off in the programing, but as soon as you touch the throttle it turns off. How do you know its coming on? Is it something you are hearing?

 

Well if everything was working according to Hoyle I'd agree with you. But there's obviously an electrical issue so what's supposed to be goes out the window.

 

We have had some a couple of tractors do that. On ours the tractors idle would drop, then it would blow out a lot of black smoke, and then the epg would shut off and the idle would return to normal. Its hard for me to remember what caused it, but if I am not mistanken we had to put a new egp on it. But I am not certain if it was the EPG itself or the controlller that is mounted to the frameor engine block depending on year. It was a couple years back.
