93 7.3 idi glow plug controller ?
I put new glow plugs in today. Still a pain in the *** to start. GPC has 12.3 volts to it(hot side) and 6 volts on the out side (with switch on start)that has the metal ribbon on it. WTS light comes on for about 3 to 5 secs like it always has, its like it never made a difference. I knew the GPs were bad to start with it. But I don't know the correct voltage on the outside of the GPC and I only have 3 or 4 volts at the plugs Is this correct?

They are autolites. I'm on a budget and couldn't afford the Beru's. But they wouldn't burn up on the first start. There is something wrong with GPC I believe or the GP wiring harness. Any trouble shooting pointers other than not using ZD9 is your reason for a hard start. I've read all threads on here I could find about this but didn't see anything about correct voltage readings.
Thanks

So what's cheaper: the right plugs (Beru's) or pulling the head to get a broken glow plug out? I'll leave it up to you....

i have seen way to many sets of autocrap glow plugs burn out after one start. and a few that burned out before even firing the engine once. they should be banned from selling glow plugs.
and i bet you paid the same thing for those autocrap plugs than you could get motorcraft plugs for too. rock auto has the ZD-9's for $9.17 each
before i ruled the glow plug controller bad, i would put the proper glow plugs in to see if that is truly the problem.
these controllers are designed to work with the motorcraft/beru plugs. the other manufacturer plugs will not work properly.
i have seen people waste all kinds of money throwing parts at these engines and finally bring it to me. i pull the garbage glow plugs out and put ZD-9's in and sent it home with the people swearing i did magic to it because they simply refuse to believe it was just the wrong glow plugs that was the problem all along.

on mine I had voltage, but some of the wires were pretty fried. Fixed all the GP wiring, works fine. I hope I put Motorcraft plugs in, but I don't remember.
