GP Resistance Ribbon Loose?
Been fighting my glow plug system since the beginning of man. Tried tightening nut on the Z shaped resistance arm and it just twisted around on me—the nut is stuck on its post that comes up from the controller and it’s loose enough to allow the Z arm to move when I try to tighten it. Can I test the resistance here to see if it’s working somehow? Do I need to get this connection more secure or is it supposed to have give?
More fun issues: At the large + terminal (2 ylw wires) on GP selinoid my reading is about 2v less than battery power—around 10.4 when battery reads 12.6. Possible culprit? Problem? And smaller post reads same with key on. Do I have a draw?
Also just changed my GPs with an OEM set off ebay. Im getting resistance of around 7-8 ohms on these, but on the one ZD-9 I put in (stripped one OEM) it’s more like .2. Are the OEM’s just crappier? Are they crappier enough for me to want to change them out asap for all zd-9s? Am I so dumb and cheap that I need to overhaul my overhaul?
Some glorious day I will stop wrestling this issue, or learn to tackle it in the summer when my hands wont freeze to my ratchet. Until then, please help.

ZD-9/Beru plugs are the only oem. If they don't say Beru get rid of them.
Check the connection between the engine and fender, that plug is notorious for overheating, corroding, etc.
I would also replace the controller or rig up your own stud, a loose connection will have resistance all over the place.

agreed. oem glow plugs are motorcraft/beru ZD-9's and the only ones to put in a ford 7.3 IDI .
if the stud in the controller is spinning so you can not tighten it up, my bet is the connection on the bottom inside the controller is broken off the stud and the controller will no longer work.
