"What does the relay in the pic control ?"
I haven't owned one of these tractors but a shop manual should tell you. Can you not tell which terminal is power in,which is power(s) out and which are signal circuit? Knowing that,you could see if 12v is reaching relay,if power is leaving relay and if signal is reaching relay coil. You might be able to hear relay open/close so I would remove one then listen to see if relay operate's at key on,lights on,hazards on ect. I have to say the fuel guage is the joker in the deck, so ground seem's to play a part in this. Since warning lights and other dash functions are acting up,how about a temporary ground jumper (booster cable) from battery post to dash assembly to see if dash isn't makeing good contact with remainder of tractor or if frame to dash ground strap is bad? If you plan to troubleshoot in the future,I highly recommend buying a shop manual. Dealer techs could never do their job without manuals,don't you think diy owners need one also?

Wouldn't the world be a better place if we all went out and sunk a hundred bucks on a shop manual at the first sign of trouble rather than say...I dunno?...crazy thought here?....asking for opinions and bothering others on these silly forums.
My Shop manual is on the way.
Tracked some power issues, or lack thereof, down tonight but.....?
Hey, go buy a shop manual and figure it out yourselves.

Well life is not that simple. I have been around this type of equipment all my life. Was raised on a 15,000 acre farm with all sorts of tractors and implements and just from reading this forum the other day I finely learned how to use a grease gun properly. Guarantee you that want be in the manual. People are still the best source for information. :thumbsup:

Normally I'd agree with you but in the case of Mahindra manuals, not so much. They are junk and are hardly worth what they charge for them.

Wasn't mice nor manuals.
Just poor workmanship.
Speaker sized wire running thru the frame that broke at a crimp.
Are you kidding me?
Would never recommend Mahindra.
Wires in the harness were at 'passenger' side down low where it goes through the frame

I am happy to hear you got it fixed. Now let's talk about your ungratefulness toward people trying to help you. I was the one who suggested a shop manual and I stand by the suggestion "exactly"the way I framed the suggestion. I have a manual for every tractor I own and they weren't bought "at the first sign of trouble",they were bought knowing they would serve me as long as I own the tractor. None of them cost "a hundred bucks",more like $20. Do you believe one of us should have been able to tell you that single wire was broke? The smartest technician on face of earth couldn't know that wire was broke. The "ONLY"logical way of troubleshooting electrical is with schematics and a multimeter. If a person is unwilling to buy both they shouldn't expect people online to help troubleshoot their electrical problems,,,,,,PERIOD. If anyone think's I'm wrong,why didn't you tell him which wire was broke? Now you can tell me I'm wrong and that you can not only ferret out your electrical grimlins without schematics and multimeter,you can do it online. Mikesdad,I hope you don't disappear now that you fixed the problem, hang around to share your knowledge.

I could not agree with you more sir.

Boy oh boy, isn't that the truth? I have purchased many a Chiltons manuals for trucks that I have owned over the years and gone into Tractor Supply Stores and bought whatever brand of 'Chilton type' manuals that they sell for the John Deere's and old time Massy's that I have owned in the past for you know, the $20 bucks or so, but this Mahindra?
Forget about it.
The dealer wanted around $100 to order it for me and I found it online at one place, Bills Tractor and Equipment ( SERVICE/REPAIR MANUAL FOR MAX 24 HST T4 MAHINDRA TRACTOR ) for $72.00.
Unfortunately, I have yet to receive the manual from Bills.
Fortunately though, I found this thread on this site....

Member drajj5 had a total loss of power as opposed to my partial loss of power but still same/same.
Both symptoms pointed to broken wires.
He also had a different model of Mahindra but the wiring diagram of his tractor that he posted was close enough for me to start understanding how the engineers at Mahindra like to tap into power supplies at many different points.
Just for an example: I have one switch that controls my headlights, turn signals and hazard flashers.
Headlights work, hazard flashers work but not the turn signals??
How can this be???

Ya well, welcome to cost cutting Tier 4 technology that ain't the ole Farmall setting out back.
Many very thin wires tap into a power source where ever they can.
And in my opinion? That is why the schematics are so hard to read and 'old school' starting to run jumpers to the dash etc is just bad business.

Glad that I found drajj5 posts from a couple years ago that clued me in on the wiring on these things being seriously mucked up.

jaxs - in reply to your post.......
I have no comment, because you have no clue.

Soldered all the connections and re-taped them since I had the wiring harness apart and didn't want to have to do this again.
Pulled ALL connections apart and applied Di-electric grease.
Applied Silicone to the backs of the the cannon plugs where the wires enter.
Also noticed a pretty large gap where the hood meets the dashboard when I was putting things back together.
The gap is right above all the relays and glow plug controller and fuse box.
Might explain water in glow plug cannon connection.
Filled it with weather stripping.
Might work.
All back together and back in business.
Still have not received shop manual.

To add to the electrical issues just in case anyone should view this thread in the future....
As I said, the tractor is 2 years old and one day I climbed on and turned the key and NOTHING.
That turned out to be a blown 50 AMP fuse right by the battery.
It was blown because I have the backhoe attachment for my tractor and every time I turned the seat around to operate the backhoe, it further stretched the already too short wires on the safety switch under the seat until they broke and shorted out and thus, blew the fuse is question.
Obviously cutting corners on wiring is a known issue with Mahindra
