Need Help Guys

[Drey]

Ok fellas. I some help. My GP controller went to hell. Im not sure where its at on this 86 6.2

Id like to just wire it up to a button, Like ive heard some of you other guys too.

Is there a way to do it so the GP light in the cab kicks on, Do I need a relay/silinoid. I was just gonna go get a Ford starter silinoid to mount to the fender wall if need be.

I cant find a good write up with pics and I dont have a clue what wires I need to take off and where I need to put the wires for the switch. I only have tommorrow night to do it too I need the truck for pheasant huntin this weekend.

I smoked the hell out of my starter tonight trying to get it to start...sure as hell when I tryed again the controller decided to work and it popped right off.

QUOTE - Locate the glow plug controller under the dash, its a black box with about 10wires going into it (located near the steering column)
the light blue wire is a ground, its completes the circuit on the relay that energizes it and makes the connection between the top and bottom terminals (thus turning on the GPs'). you can just run a new wire from the small terminal on the front of the relay to your switch. on the other terminal of your switch, you need to run a wire to a good ground. (in my truck i grounded it to the dash, but be sure to scrap off the paint to bare metal if you do.)

Your switch needs to be a momentary ON switch..

By doing it this way your wait light will function as normal if your controller card is mostly working. since the most common point of failure on the cards is the chip that switches the ground to turn the glow plugs on.Locate the glow plug controller under the dash, its a black box with about 10wires going into it (located near the steering column)

So I just use that blue wire that runs to the controler and use a switch to ground it out to make the glow plugs go on..Correct?

Correct.

under the hood on the controller I have a black, two red/purpleish ones, and a yellow wire so no blue right there. Theres a light blue wire with a Green in a two pronged plug clear over by the master cyclinder


Under the dash I found what I think is the CP controller there, smaller box kinda like a mini TBI computer. Cheap plastic and real light in weight, with a AC on the side of it. There I found a light blue wire with a black stripe on it the plug is that the wire I can use for this mod?

I have no black box with a blue wire. Mine is an 82 though. I see a pair of light blue wires on a silver box with 2 connectors into it and like 8 wires. There is a plastic cuircut board box with only 4 wires going into it(none are blue though). I tried unplugging connectors and turning the ignition to see if the GP relay cycles and no mater what it is working.

also note I am running a non military 12 volt dual batery system.

My 82, like yours had the circular 6 prong plug controler, the controler was broken and the contacts were exposed so I would wigle the top piece untill it touches the groung wire and it goes on, I finally traced it and found which one it is and always used it but never thought of writing it down so now I can't remember what color it is

Yeah 85 and older is the easy style of glow plugs.

where was it located. It works just int it will come on when i am driving and I have to unplug the relay. I just want to put a kill switch in place.
