Thanks for the reply, nyone. It's not that the instrument cluster is "going dead", intermittently or otherwise The gauges jump radically when hi-lo range switches are touched and the battery light stays on the entire time the engine is running. I know that the battery light staying on is...

Thanks again. Very much appreciated. I’m afraid I will have to spend a little time deciphering some of that, but will work on it.

Wow. That last post of mine was May 6, 2022. Today is November 10, 2023 … and the problems with the New Holland TC40DA are STILL the same.

Thank you for the information. I’m still trying to open/download the image you posted. I did get the tractor to start and run. I discovered that one of the relays had gone out –– which I had previously checked, and was good earlier. And a hot wire going to its neighboring relay had corroded in...

Thanks. I figured it was a long shot, but thought I’d ask. I got my TC40DA to start/run, but it still has electrical issues with the hi-lo range/third function operation/dash and gauges. This electrical anomaly has plagued me for about three years!

I’m not familiar with a “pigtail” nor how one is read. Thanks for your great response. I have a VOM and can use it. Also have a tool that inductively reads/follows current in wires. It has proved to be invaluable for the New Holland. I think my biggest question for the post was whether or...

@Papasmirf (post 11/21/13): I know it has been 10 years ago since your post, but I would sure like to know just where you found that “small ignition relay“. I have a 2004 TC 40 DA that I have searched pretty much anything and everything electrical on and it has been weeks but all it does is...

I am so thankful for this Forum and all of the great folks posting herein! This thread is getting some years on it, but it is still providing very good information. My sincere grat to all the contributors. My 2004, New Holland TC40DA has been giving me electrical anomalies pretty much since...

Update: I got the tractor to crank/run! On the third time through all the safety switches I discovered that the Range Selector safety switch (located on the side of the transmission) has gone out. When I had checked it before, I had discovered that the wires had pulled loose due to some...

It has been months since I’ve been back to the forum, but it doesn’t mean my electrical issues are by any means gone. I’m fully aware that in these times everyone has their own “issues” going on and it is my sincerest hopes that you all are doing well out there. Back to the New Holland. I did...

Kirkawilson, THANK YOU so much! I have needed this from the start. But now I’m very confused, I have never changed any fuses in this tractor before this, and my number one and number five fuses are both 25 amp fuses. I assumed that’s what it needed since it’s been running for years those fuses...

Thanks. I am going to try just that … once the rain stops (I’m out in the elements here). What is it with me and electrical systems? My Dodge Ram dualy is now having both batteries drain to nothing, even though gauges show system IS charging!? AND, my rear passenger power door lock has ceased...

I want to thank everyone who has offered help and information. I regret that it has taken me this long to get back here and Update but there have been so many things going on lately that I don’t know whether I’m coming or going. When I originally checked all the fuses, I accidentally missed a...

Curses! I posted - or thought I did! - a reply on the 8th. Don’t know why it didn’t actually post; maybe due to weak signal/ connection. Anyway, I bought multi-meter. Initial battery voltage (before cranking) was 12.5 volts; engine running was 14.9 volts. So, alternator IS definitely...

Update: Finally got the top/dash and left-side cowling off (still have two bolts stuck on right-side). Cleaned out the “rat nest” and cleaned up all the electrical components. Had to patch several wires that had been chewed completely in two and reward several more. There was a whole lot of...
