OK Guys, after checking all the circuits, removing the glow plug, testing it and the circuit for proper resistance and having everything check out, I surmised it was the glow plug controller. (Part number 68149041AB).
I pulled and replaced, as I wasn't sure how I could check the relay since...
OK, I put the glow plug back in. the circuit to the number 2 cylinder checks out. I'm guessing it must be the controller. Will order one and replace and see if that fixes the problem. Will reply back with the results.
I tested mine with a battery and a multi meter. The plug lights up using only 4-5 amps. plus it ohm's at about .2 ohms. I think the plug is OK. i'm now thinking maybe the module or a bad connector / wire. getting ready to run out and do some circuit testing.
Finally got some time to work on this. I got the plug out. took about 20 min of back and forth with a lot of PB Blaster. I checked the GP with an ohm meter. it's showing about .5 ohms. I'm trying to rule out the plug or the glow plug module. Does anyone know what these should test at?
Hey guys, I have owned a few diesel trucks over the years and one diesel car that I still have. overall, I've had pretty good luck. I recently had a problem with my Ram Ecodiesel with glow plug failure. I joined the forum as it was the only place I found that helped me identify where and how...
