glow plug problems

went to test the glow plugs but the wires dont seem to want to come off easily, #2 came off easily but the rest of the plastic connectors are all corroded and pretty much fell apart. Also looks like one is missing #3 (or broken off) I believe. can anyone tell me how to properly test and/or remove them? thanks

the relay clicks on and off constantly when I turn the key to on position. lasts about 30 seconds. Is that an indication I need a new relay or is it just the glow plugs?

Sounds like you need a new relay I would go ahead and replace the Glow plugs too.

if this is for the 93 listed in your profile, use the motorcraft ZD-9.
you can get them from rock auto for around $10 each.

To test the gp's take a 12 volt test light and hook it up to B+ then touch the end of each glow plug. If it lights it is good if not it is bad. I had to remake my gp wiring harness because connectors where bad I used 8 gauge for the main run with 12 ga for individual gp wires and female bullet connectors. all soldered and shrink wrapped.
