Cruise control

Recommended Posts

I have a 2013 Mack GU713. Just a little back ground, this truck is a hot oiler that has a secondary throttle control on the side of the truck so the operator can control the engine from the outside. The throttle control is tied into the cruise control so you can idle the truck higher or lower from the out side. Anyway the operator tried to replace the external throttle control on the outside and arced the power wire on the box in the process. After that happened the cruise control quit working completely. I have looked at both fuse box diagrams and cannot find a fuse or relay that says it is supposed to control the cruise control. Also I have tested all the fuses and haven't found a blow fuse. If anyone knows what relay controls the cruise control please let me know. Any and all help would be appreciated.

Fuse 17 powers the cruise control switch. Its a 10 amp fuse located in the upper bussed electrical center.
