Make sure starter relay has a good ground connection.
Not possible. The block heater has it's own cord that runs from it up to the front of the truck. The end of this cord plugs into an extension cord coming out of a 110V receptacle. Those are two completely different electrical systems.I’m thinking the block heater may be opening the limit switch on the starter. What do y’all think?
How do you bypass the switching valve?
