So I successfully found the key off parasitic drain on the peterbilt... I have to say I found quit a bit of difficulty when I tried to use the same tactics I used on the international. I found it by checking the load on the fuses. Then used my meter to check the outlet (where the fuse box lead me). The outlet had no power so I pulled covers off and found a damned resistor behind the ash tray. Hours this week:15. Hours total:40
