    Default Electrical problem?

    I have a 2003 Silverado 6.0L, while driving when I let off the gas all my electrics will dim and sometimes three to four time a day the truck will just stall, it can immediately start up and keep going no problem. No check engine light or warning lights. Also sometimes when I start the truck or come off the gas the horn will flicker. I've cleaned the terminals on the battery but no help.

    How many volts do you have with the engine off and with it idling?How old is the battery?
