Hey everyone, so my truck has been running perfect until today. I went to start and had no power at all in the cab except for a “Charging System” red light on the dash. My truck has battery disconnect near battery box and it’s always stored in off position. Today I turned the switch as usual and the red light came on the dash, I have never seen anything on the dash light up before without turning the green power switch on dash on. I then turn the green power switch on and Nothing, no power to anything, no buzzer for low air and no crank or clicks from relays. I have charged all battery’s and they at 13v. I have also checked all power connections and seems to be ok except im only getting power to one side of the solenoids after the battery switch. I have attached a drawing for reference. Can someone please help as I have never had a 0 power issue before. I have also attached picture of rely board but my sticker showing what relays do what is missing so I have no idea what to check. Thanks for the help I really needed to use the truck today and am completely stumped by this.
