Buying Advice Wiring delima

longrider · Apr 4, 2019

I own a Nortrac 204C 2007 with the Y380 engine. I replaced the fuel tank, so I disconected the wires under the dash including all the gauges. My problem is when I started to reconect the wires I looked in the owner's manual and found the diagrams and wire numbering do not match what is on my tractor. I looked all over the net. Any information would help me out of this pickle. Thanks.

Been there, done that. Sorry I can't help with your specific machine, but I can offer a piece of advice to keep it from happening again in the future. I always take pictures with my phone (multiple, from different angles, with the flash on to be able to see stripes and colors on wires) before disconnecting anything complicated. That way I can always at least get it back to the way it was before I started. Hope someone can help you out!

Thanks I'll remember believe me.

A lot of times, especially on machinery that is a few years old, the wiring will take a set, and will want to go back into it's original position when the loom is moved back into place. The terminal ends and connectors should pretty much swing into place and not need to be 'fussed into position' like a new wire would.

This has saved many a shadetree mechanic. :thumbsup:

However, sometimes there's just too many "too-close-to-call" wires, and it leaves you scratching your head.

If you're not certain, you may have to go through the process of ringing out wires from source to destination. It's frustrating, but you have to do it or risk damaging things.

I will look into that. Much appreciated.

That is a last resort but your right I may have to do it. I have also been thinking about disconecting all wires and then only reconect what is needed to operate the engine and since it is a desiel it may be another option either way it will be frustrating. Thanks.

Look at it this way.... you'll get a self-paced education in tractor wiring 101. :thumbsup:

Just a W.A.G. here, but won't the gauge be wired directly to the sensor that measures what the gauge is displaying, and the other wire is connected to a common neg (-)? I know that sounds overly simple when in reality it's not. But wouldn't one expect to see the same color wire at the pressure or fuel sending unit, or temperature sensor, etc.. that you see at the respective gauge?

Did OP disconnect wires from key switch? Those would be tricky reconnecting.

MossRoad · Apr 5, 2019

Yes, you'd hope to see different color wires on each sensor, and you'd hope that wire goes directly to the gauge.

I have decided to look for a simple start circuit. The owners manual has no valid information so I am looking for a diagram of the barebones start circuit. Does anyone have an idea? Thanks.

Don't disconnect anything more than you've already done.

Even if your wiring diagram isn't accurate in terms of the color or numbering of the wires, it is accurate in terms of how it's wired. So if the diagram shows a wire going from the start switch to the clutch switch, you will have that wire. Look at the two wires on the clutch switch, get their numbers and colors, and then look at the wires you took off of the start switch and find the one that matches. You can do that with all the wires you took off, find the other end, and then look on the diagram and see what wire goes there.

For future reference: there is a white plastic multi-wire connector near the fusebox that disconnects the front wiring harness from the rear. It's there because in order to replace the clutch or work on the transmission you have to separate the front of the tractor from the rear. I'm pretty sure you could have gotten the fuel tank out just be disconnecting that one connector.

Did you get this sorted? Start circuit is actually pretty simple although the exact detail will depend on your exact key switch. My switch has four positions, Off, On, Heat and Start. Off is fully anti clockwise. Heat and Start are spring loaded back. Moving to the back of the switch there are four terminals, (1) is Live with 12V from the main fuse or ammeter. (2) supplies instruments and other stuff that only works when the switch is On. (3) is Heat and (4) is start. Start is a fairly heavy cable running down to the solenoid on the starter motor.

He's gonna have trouble downloading that file.... it's on your C drive.

I definitely wouldn't open up your C drive to the internet if I were you.
