I have a Mack Pinnacle daycab from Old Dominon leasing for the next umpteen months. There are 2 switches on the dash I don't understand. One has a picture of the battery on it, and the other has what looks like a key on it.
Whatinthehades do these switches do? Checked the owners manual, didn't cover them.

They lighted when on and located over by your left leg but on the dash?
-
If so they are for the technician....I have a pair on the CH.

Accessory Switches,Battery Power and Ignition Power.
It is under Function of Optional Switches in the owners manual. -
Their not by my leg, they are on the dash with the rest of the switches.
Accessory switches sounds right, thanks! -
one switch is an accesory switch tied to the battery, the other is an accessory switch tied to the key, I have the same on mine.
bottomdumpin Thanks this. -
Do you have to add a wire to the switch? After a brief look there is not a loose pigtail from the back of the switch.

On my truck the battery button controls power to the inverter. I've never figured out the key button.

I have a 2013 CH ad my manual says the battery switch is for "auxiliary power". My mechanic thinks it may tie all 4 batteries together to start the truck if the batteries are down. Only my driver's side batteries are hooked to the starter. I have a switch that has a cross hair looking emblem with a circle behind it. Anyone have any idea what it does? Doesn't say in the book. It's a momentary switch and doesn't stay in the on position. Haven't hit it with the ignition on yet
