we remove the wires all the way from the solenoids to the heaters. the industrial 5.9 does not have heaters. cummins part number with out the heater is 3922484. it will throw two different codes. the green control wire to the solenoids must see about a 20 ohm load that is why most leave it connected. the second code works like this, once you turn the key on the wait to start light comes on regardless of temp. this trains you to wait to start. only when the temp is below 55* does the ecm trip the heaters and the ecm watches for the voltage drop to ensure the heaters are working. simply do not wait to start.
