Glad I moved over to Poly Trucking

Push in the yellow break button, while keeping the red break button pulled out. Make sure you trailer breaks are adjusted.

 

I tried that and it shut off in 15 minutes .
Another driver showed me a way with the cruise control button, the words "engine throttle" illuminate on the speedometer. I tried it and it worked but a few minutes later down the road it didn't work. I will play with it throughout the day.

 

I drove a 4 yr old KW T680 that I could keep running by jamming a stick on the throttle so it would idle around 700 rpm. Ran all night. Newer ones won't.

 

Yes some are designed to shut off once the truck motor idles at below a certain amount of revs the idea is you'll need to keep the revs up to a higher level I'd usually adjust mine to about 1100 rpm as running an engine to long at low revs is not good for the motor.

 

Tape a hand or pocket warmer to the temperature sensor on the mirror

 

This is a bobtail friendly grocery store close to the yard, turn onto nw 10th off of Main street.
