New Holland TC27D Wiring Diagrams

[jonwhite]

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

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

You might try Messicks as they have parts diagrams for just about everything.

Sadly, no.

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.
