Thomas MVP Fast Idle Switch
Hello all! This post is regarding a 1993 Thomas Saf-T-Liner MVP ER.
So we are working on our skoolie. Currently halfway through putting up outer sheet metal. But today we figured we'd go ahead and fire it up and make sure it'll still run since we haven't turned it on since February :P I was only somewhat familiar with the fast idle switch, which I knew that the left switch. After a couple minutes of it running, I wanted to turn on the fast idle. I flipped on the left switch, and I assumed the right switch was to adjust idle speed, but the switch broke very easily.
My question isn't so much asking how to fix it, but I am just trying to verify what the right switch in the Fast Idle controls is used for. If it is for idle speed setting, then I can't adjust the speed and is currently stuck at 1500rpm. I'll attach an image. Thanks a bunch!
