I'm burning up a couple of glow plugs(sometimes same, sometimes different ones) every time I start the truck in the past week. They seem to cycle correctly. But i have 24 volts from the resistor to the top of the solenoid. I figured I should have 12 volts there, since thats what the resistors are for. Could somebody check theirs for me? When they cycle it does drop to 12 volts under load. I just emailed SSDiesel about some 24 volt instant heat glow plugs, and may get rid of the resistors all together.
