That doesn't make any sense at all? The relay turns on when the key is turned off to keep the tank selector valve energized? Seems like that would be hard in the battery? Isn't the tank selector switch a momentary contact that energizes the solenoid briefly to make the valve change while you're pushing the switch? The valve is not sprung it isn't normally closed or opened, it is flipped whatever way the current last ran through the coil isn't it? Not calling the guy a liar or an idiot, it just doesn't seem right and I'm wondering if there is more to the explanation.
