Dome lights, cb, cigar lighter no power

this is battery protection relay if someone remove the batteries or voltage is low then it will cut out all the excess drains on the batteries. The way i take care of this issue is simple take a jumper wire and connect from a good power source to that fuse row when the vehicle is running leave it for about 5 min and it should reset itself and everything go back to normal

 

this relay shoul be located on left hand of fuse box it has a yellow sticker on top

 

Battery protection relay is located in the sleeper heater control unit. If resetting doesn't work, look into the relay itself.
