when it cuts out Throttle off Reverser in neutral Underneath reverser the furthest left switch to front flick to start if I recollect. Hold green start button on dash for five seconds or so Flick the switch to run under reverser Back into forwards By now you should hear it throttling up again. Hope that helps.
I actually looked up the class 66 restart and found multiple posts, one of which I'm sure was from you and tried for a good half an hour in vain to get it to restart. I went to the other end and tried there, nope. I tried flicking all main circuit breakers off/on then following procedure, nope. I then watched several YouTube videos of cold starts but whatever I did it wouldn't reset. I did just give up in the end as the frustration was loading having to give up a half hour (minimum) journey 3 miles from the end
Not sure what else to suggest in that case. I'm still chipping through the 66 services so I'll keep an eye on what I do if it happens again. Good luck
ollyweston350 - Just had a quick muck about this morning for you and did the below. Not sure if it helps. Not advocating this is prototypical but it got it started.
