gp controller stuck

[82fordtruck]

My controller got stuck on today. The wWTS light works fine, but the controller stays on. It clicks on when the key is turned, and clicks off when the truck is turned off.

I ran my gp's for about ten minutes before I figured this out. I just disconnected the wires from it, so that I can get where I am going.

Anyone have any ideas?

I appreciate any help, I need to get this done tomorrow so that I can get to work.

Which wires did you disconnect? The large +? Try running a bypass.

There are acoulpe of ways to do this.

ONE: I added a wire (but you should just remove the white gnd wire)from the WHITE wire terminal on the GPC and ran it to a momentary switch on the dash. Then ran a wire from the other side of the momentary switch to groung. This way I can push the button after the Wait To Start light goes out for a few more seconds to heat the GPs some more before I start. It'll still work automatically.

TWO: Take the WHITE wire OFF the GP Controller(GPC), and insulate it with tape. ADD a wire from where the white wire had come off, and run it to a Momentary Switch on the dash near the Wait To Start light,
from the other side of the Momentary Switch to a good ground.
Also cut the Blue/White wire going to the GPC and connect
that to the terminal on the GPC where the white wire was attached(you’ll now have 2 wires on that terminal), that will make the Wait To Start light come on when you press the button to glow up the plugs for however long you hold the Momentary Switch. If you don’t have Motorcraft Glow Plugs, I don’t recommend this procedure.

THREE: Go to www.webshots.com plug in my username (bajajeeper) and look at the uploads I have there. You'll find what you need. OkieGringo

I disconnected the final connection to the gp's in case it shorted out.

Surprsngly, no gp's are out!!

I want to fix it, and will add a manual override to it, along with an indicator light in case this happens again. So, for now, I am focused on fising it right. I did get a lot of information from you when I asked about the manual override though. I will use that when I do it.

This site is the cheapest I've found for new GPC but by the time you add shipping you'd probably be better off and quicker to just go to A/P store and pick one up at around $120. Check your wires the small white wire just might be shorted to ground.

At that price, I've got 2 spares sitting on the bench.

OOOPS!

I just read your handle, and assumed your 82 was a diesel.

well, I just cleaned everythging, and no luck. I'll buy a new controller now i guess. My ground is good, .2 ohms between the battery and the controller.

We just had a post here or over at TDS about just replacing the relay that sits on top of the controller. It's about $52 at Stealership. Might save ya a little money. OkieGringo

the relay is clicking, that wouldn't be the problem, would it?

well, definitely bad GP controller. I bought 8 new plugs too. Didn't want to push my luck, and I know I burned some out. Wiring seems good though - thank God.
