DELETE - DOUBLE POST -Sorting out a manual glow plug question
OOPS - Double posted - SORRY!!!!
Okay, here's the basics: I've got an '85 6.9 - the previous owner put a manual glow plug switch in.
The glow plugs have never worked as long as I've had the truck and frankly the fear of snapping them as they came out scared me off swapping them and fixing.
Finally getting around to it. Couple of questions.
1.Is there an easy way to test if this manual controller/switch system still works? What voltage should I be looking for where?
2. Looks like folks prefer the Motorcraft ZD1a - correct?
3. Is there any chance that the controller/switch would require a different glowplug from the ZD1a? If so how can I figure that out?
4. Best practices for removing these glow plugs? I've got a couple of days because I'm waiting on other parts.
Thanks so much for the help!

on the old style controller that your 85 has, the controller failed in the on position and would burn out the plugs.
thus the reason why people went manual plugs. and yes, motorcraft ZD-1 glow plugs only.
