Kenworths.... Check battery box. Look under the hood? And may not look like your standard relay. May look more like a solenoid. Older KW's had constant power relays in the battery box. Can't remember if those were for ignition or not, and not sure if the newer 800's have them.
Okay, thanks. I know it had an extended idle shut down timer but that had been turned off with a laptop at some point. Obviously I am just guessing at this point. Thanks to all yall with the experience that take the time to help us.
