801 powermaster diesel glow plug wiring diagram

Need help on wiring up glow plugs if someone has a diagram to help me thanks

I may be wrong, but I'm pretty sure that the 801 series diesels did not have glow plugs, not even as an option.

'll make a WAG & say that he is referring to the "manifold heaters". y/n?

They had "manifold heaters" which were 2 spark plug looking devices that were screwed into the manifold.
Get another starter relay (solenoid) exactly like the one that starts the engine (Ford 311006). Run a heavy wire (about 4 gauge) from the battery side of the starter relay to one of the large posts on the new relay. Run another heavy wire from the other large post to the manifold heaters. Run a small wire from the switched side of the terminal block through a momentary push to close switch to one of the small posts on the new relay. Run a small wire from the other small post to ground. The heater relay and it's push button switch were originally mounted under the hood on the left side of the center dash on the horizontal portion of the lower dash panel.
Now when the key is On and the momentary push button is pressed the relay will activate and send power to the heaters.

The wiring diagram from the Ford shop manual is a little hard to understand unless you know what you are looking at.

It uses a starter relay (solenoid) and a push button switch.
Run a wire from the key switch to the push button and then another wire from the push button to one of the small post on the relay. Ground the other small post on the relay with a short piece of wire.
Now run a heavy wire from battery + (you can get this from the large post on the starter relay) to one large post on the relay and then a heavy wire from the other large post to the heaters.

Ok thank you sir thats what i needed to know

Baggie · Nov 19, 2012

Its my first time on here i thank all of you that responded im sure i will have more questions on down the road

Would this be the same basic setup for a 3600? The only device I have on the panel is the key switch, so I'm not sure if I'm missing something, or if they did it differently on that model.
On the key switch, I found that one of the terminals switches to hot just before the actual start solenoid is engaged, it's only a momentary position, let go and it springs back to the run position. I assumed that you'd just key and hold the switch just short of engaging the starter to fire the manifold heat for a bit and then crank it over, but I'm not sure after seeing this post.
Thanks,
Eric

30_Eric - No, the 3cylinder diesels had something called "thermostart" as an option, which dumped diesel fuel inside the intake manifold and lit it on fire to preheat the intake. Not all of them had this feature though, as I said it was an option. Look at the New Holland parts web site for the parts breakdown, it's got it's own parts diagram for the 3600 labelled "diesel cold start".
