I have another problem on the magnum. While replacing the starter relay I found a ground wire on the mounting bolt and it was burned off. It goes back inside the harness and was burned as far as I could see into harness. My question is, does this ground wire run to another component in the tractor or is it actually a ground for the starter relay.

I see no special reason for a separate ground on the relay as it is mounted to some pretty heavy supports that are inturn bolted to the main frame work. I did not add a ground wire but did add those piercing type lock washers to make sure relay got a good connection to ground.

As far as I know everything is working ok on tractor. Not up on these later magnums though.

As far as the battery drain, my tests showed right at about 15 mil amps draw. It does the normal computer system type deal where the first few seconds you hook up it will draw more, also light up a test lamp, and then the lamp will go out and or gauge drops to the 15 mil amp draw. I am discussing with owner, the options of float charge, disconnect, pulling the three fuses or just unhooking ground cables during long non use periods. Pete, I have no experience with a MX 240, but i went back and read your original post. I am an electronics technician/electrician by trade and when you find burned wires you need to get into (if you can) that wiring harness and see what is going on.

If you have wires getting hot this will drain your batteries and it will get worse, i know i am just guessing here but it sounds like this burned wire is the cause of your problem. Are there a lot of wires tightly bunched together? Any evidence of rodents they love insulation, I had a person one time where the headlight wire in his truck got chewed and grounded turning on his headlights! Could'nt turn em off! Ok maybe that will help, keep us posted, Tom.P.S. Milliamp draw on those size batteries would take months to even drain a few percent of full capacity.

That burned wire really concerns me and I am not done checking things yet but haven't had a chance to talk to the owners.

I just wish I had a wiring diagram to see what that ground wire actually does ground as it could lead me in the right direction. Hey, as far as mice, ya I know. I worked over my grandson's Honda's air cond. Year ago I checked it and compressor was leaking. His dad, my son, finally got around to having me repair it for him this hot july. Well, now the hose was off,(how that bolt fell out and let hose off I'll never know). Anyway, I replace compressor, bad condenser, receiver drier, flushed, evacuated, charged system.

It didn't work, no power to compressor. Hot wired it to make sure air cond actually worked. Searched internet for diagram. Finally determined that the relay controlling compressor clutch had no continuity to ground which is controlled by the computer. Told them, no charge, just don't bring it back.

Some one smarter than me finally got to the bottom of it. Mice had chewed off the wires some where between relay and computer.

Car had been in storage for a few months during winter. Heck, I couldn't even find the computer. Anyway, problem solved. I kind of enjoy working on electrical parts of a system but when you are not familiar with a product and have no diagrams you are just spinning your wheels. Sometimes even having the wiring diagrams don't give you a clear picture. I worked on a 2006 medium duty GMC where the wiring in the truck did not match the wiring in the service manual. To make matters even more interesting the placard for the fuses and circuit breakers in the truck did not match the manual and neither matched how the chassis was actually wired.

I was thankful that I still had a paper copy of the service manual. It really tough to write notes in the margins of the pages on the CDs. You should check the ground wire out cause it could melt the insulation off some wires next to it and start a fire. It could, but i hope in this case the wire acted as a fuse and disconnected in time. What size wire is the burned one 12 AWG or larger?

Gives you an idea as to how many circuits are grounded through it. Also is there anything on the tractor that no longer works? Your customer may find out when he needs it most. I think a trip to a Case IH dealer and some more research into the wiring harness is in order. A short can be quite far up the line but the ground wire will burn at the point of contact to the chassis. Best of luck.

This was a common occurance on Gen. I MX Magnums. This problem is the main engine ground cable is making a poor connection with the frame(or 'bathtub' as I call it).

CaseIH used a braided negative battery cable from the engine block to the frame that gave a lot of problems. Either the braided cable or the bolt connection at the frame can give problems here. With a poor connection here when the tractor is started the ground tries to go through that wire on the relay-a 12 or 14 gauge wire instead of a much larger battery cable. I would encourage anyone with a Gen. I MX Magnum to inspect the engine ground regularly so this doesn't happen. This was a common occurance on Gen.

I MX Magnum to inspect the engine ground regularly so this doesn't happen. Thanks for that information. I will check out that engine to frame ground strap. Next question, just where does that ground from the relay end up and should I add a new wire,it seem rather unnecessary to me as the relay appears well grounded.

You are logged in as a guest. ( ) Case IH MX240 Zero Return:: - Message format Posted 7/24/2013 23:07 (#3227871) Subject: Case IH MX240 Zero Return NW Oklahoma I am running an MX 240 tractor for my sprayer tractor.

I have been trying to get it set up and am running into problems with the zero return. According to my service guys, the female outlet on the right side directly above the #2 hydraulics should be my zero return.

I was a little confused by this as it is the same diameter as the other hydraulic outlets and takes the same typical pioneer hydraulic end. So, we tried it and had the same luck as when we use our hydraulic receptacles as the return.

In a short time of running, the trans hydraulic fluid gets hot (from about 185 degree normal temperature to about 208 degrees ). So, it appears as though this may not be a zero return, but I wanted to ask anyone on here if they know. I need to know how to get this sprayer set up so it doesn't heat up my hydraulics. I am going to include a picture. The outlet that the Case service guys say is the zero return is the one on the upper right of the image with the hydraulic hose plugged in. So far, if I turn the flow rate down as low as possible, I can still spray without the fluid getting over 200 degrees, but I am limited to about 7 mph.

Also, I can keep the system cooler if I disengage the other hydraulics that control the boom height. The set up is a Shaben pull behind with electronic controlled booms. Any advice is appreciated.

Download the pdf file at and go to. It calls it page 16 of 28, but my Foxit Reader shows it as page 26 of 38. It says: If tractor is equipped with power beyond, then use the couplers as shown for case drain and motor return. If tractor is not equipped with power beyond, then plugs need to be removed and couplers need to be installed on the valve assembly as shown.

I have the manual in front of me with 2 pics, one with Hydraulic Power Beyond and one with Motor Return Circuit they both say (if equipped ) sad to say neither looks like Martinag pic. But the motor return circuit one, does a bit, which goes along with what Mike said (but where low return pressure is desired ).Hey Martin is the top of return hydraulic block bleached out by the light in your pic just realised that if thats the case, Mikes on the money. Tractor before this one was a Magnum 7120, I put return straight to transmission and if have bleed off put that there too.
