New Holland TC27D
Anyone got a workshop manual for a New Holland TC27D tractor? I am trying to understand the glow plug wiring on our 2004 model.....and struggling. Desperate to look at proper wiring diagrams. Thanks :)

TC27D doesn't come up for some reason, but partspring kinda has electrical diagrams.

Not proper ones wiring diagrams, but they have diagrams of what wiring is where.


Might have to see if you can buy a copy of the workshop manual to get the proper electrical diagrams.

Thanks James. I know. It seems strange that TC27D doesn't seem to come up anywhere online

My owner's manual for the TC40DA has the wiring diagrams at the back of Section 3. Don't know if your manual would have the same.

interestingly the model TC27D doesn't show up on the Messick Website, wonder if it was sold outside of the US:

I wonder how similar a diagram for a TC25D or TC33D would be?

I thought the TC27D, TC29D, and TC33D were the same tractor except for HP.

edit...my parts book has the 25, 29, and 33 models.

I won't be surprised. My owners manual is for the TC35DA, TC40DA, and the TC45DA. Same tractor, different HP too.

Pick a diagram and a component then see if the diagram matches what you see. Wire color or wire number.

I have a TC27D manual - nothing in it apart from fuse box layout if that's any good to you. I have had a quick look, there was something online ages ago that I use to use, think it might have been through a CNH parts list, and it had wiring diagrams - can't seem to find it but will keep looking for you. You are right about the TC27D - ever other model listed bar the aul' "27". What are you trying to wire/trace?

Hi, did you have any luck with getting a manual? Cheers.

Here is the portion of the wiring diagram for my TC29DA that covers the glow plug circuit and some pages from the service manual that contain the glow plugs, fuses, and relays. It's not the exact same tractor, but what you are looking at must be the same or really close: the glow plug circuit is not that complicated. I have experience testing my glow plugs (ohm and voltage), so you could search my name for other related posts, including testing/replacing the timer relay and adding a push button to activate the glow plugs.

Those wiring diagrams can be a pain to track down unless you’ve got the full workshop manual. The New Holland TC27D service manual covers the glow plug circuit in detail along with all the schematics you’ll need. You can usually find the proper manual online here: Home - Download Workshop Manuals – worth a look if you want the complete diagrams.
