Why the truck clock radio won't turn off when engine is not running

Alternator may be faulty and not charging the battery or you may have a voltage leak to ground which is discharging the battery like a clock or radio light or some other faulty electrical component leaking power.

The alternator is the easiest to check. Does the battery go flat as you drive it? If not its probably not the alternator. You could check it with a current meter when the engine is running.

You could do the same with the battery when the engine is off to see what the current drain is. This might give you an angle on the thing which is draining the battery.

it might could be the starter im not 100% sure try getting it check

Check your fuses, look in your owners manual to find exact location. Usual places are on the sides of the dashboard, underneath dashboard, or it may be in the engine bay.

The radio and BCM needs read for codes. No reason for the radio not to work after a FOB program. Just a guess, but if the battery power was to low, radio is locked out.

look for main fuse panel under hood, there should be a charging circuit fuse check it

Check your alternator by starting engine and removing negative battery cable while running. If engine stops, replace alternator.

Check battery ground wire or get a new battery.

Radio and clock/interior lights are two different circuits. Check your fuse block to see if it has power.

I found a paritally blown fuse. When the fuse blew metal pieces ended up partially making contact. After replacing the fuse everything worked great.
