electrical question, help,

[jrubicon]

this might be a stupid question... when the key is out of the truck for a long time, is the radio suppose to work?

 

I am trying to locate a parasitic draw to the battery. my problem is there is power in the hitch now all the time, it used to shut off after a moment after taking the keys out.

 

power in the hitch connector should turn off after awhile correct?

No, it does not shut off. The 12V provided to the 7 way socket should be hot all the time.

I just checked my truck, haven't driven it, pressed any key fob buttons or opened any doors since last night. It shows 12V to pin 4.

The radio does work for a while after removing the key and even after opening the door. Maybe to not drop calls if a call was in progress when shutting off the truck?

I still see GMC Intellilink in my phone's Bluetooth for a while after shutting off the truck and getting out sometimes. Kinda annoying actually.

One time after a phone call I took through the truck's radio, it got stuck thinking the call was still active, unable to hang-up, even after powering off my phone!
I had to remove the key and leave the driver's door open for 5 minutes to resolve it.

Not sure if any of that is on point but evidently the radio is alive after removing the key and opening the door.

The 12V 7 way plug should always be powered.
