Hello all, I have a 2010 Peterbilt 386 with CAT motor. I have lost all my dash gauge lights and the guage needles are also inactive. I believe they all tie in together and must go through a fuse somewhere. Does anyone know what specific fuse "name needed" and location in the truck for the fuse that handles the dash guage lights and needles. The only guages that work are the speedo and tach. Thank you for any help you can offer.

They are all comuter controlled. Looked for a fuse labeled "NAMUX" or possibly "CECU". They are usually in the regular fuse panel by the clutch pedal, but I'm not familiar with the 386's. If the fuse(s) are good, you'll need a shop with the ESA program to diagnose.

Hey y'all ...
I just had this same issue on my 386. Fired her up and no dash lights. I pulled the fuse and it was fine so I started googling. I tried a few things I read about but nothing worked. Being a former radio op in the Marine Corp and the hours and hours and,more hours of preventive maintenance I thought about corrosion. So before I sent a breakdown call to get permission to go into the shop I pulled the fuse again and using a pencil eraser I cleaned the connectors. Wouldn't ya know it soon as the fuse went in my lights popped on. Just a thought but if you have this issue. This is what worked for me.
Be safe , God bless -
Hey btw this 386 is a 2013 with less then 200k on her. Corrosion is an ugly monster that can show up at aanytime.. Hope this saves someone from an inexpensive shop call
