[QUOTE="Big Chief, post: 5272817, member: 313926"]OK guys here are a few tips for you Emax 22 HST owners.
 Just recently I begin having starting issues in the morning. The temperature is only around 30??ｰ which I felt should not of been an issue. The tractor will take several attempts to start while billing heavy black smoke. 

Once warmed up no problems at all starting or running
I did some searches and looked into the 10 AM fuse which I cleaned and put back in and had no effect.
 The glow plug light was turning on and staying on and for good 30 seconds but I still had heart start issues 
 I also had a check engine light appearing on the dash which would flash too long lights and for quick lights which I determined to be 24. Apparently that code as no meaning in the Mahindra literature. 
 I ohmed out the glow plugs in they checked out normal. I remove them and bench tested them with 12 V and they heated up fine. I also had 12 volts on each glow plug with the key on. 
Something was still not right.

 I spoke to the dealer where I bought the tractor which is Johnson auto in Bethany Connecticut. They recommended a look at the glow plug relay wiring. I did just that and I found that the wiring harness was rubbing on the frame. I pulled out the relay  put it back in and it started right up. 

 The relay is buried inside the engine compartment almost impossible to get to I extended a harness and relocated to a much more convenient location. It has been working fine now for a few days and start it up in 5ｰ yesterday morning without a problem 

 Here is the kicker the power steering hose that comes off of the hydraulic pump which goes up to the steering wheel was completely worn through along the frame because it is such a tight fit with almost no extra hose to allow any movement. 
It was starting to slowly leak and it is almost impossible to see. You have to disassemble the entire dash  pull the steering wheel and the steering head unit to get the hose off.
 I was going to order an OEM hose but decided to have one made a few inches longer to keep it away from the frame. 

Take a look at your machine guys it may save you a huge headache in the future when you are in the middle of doing a project

I had the same bracket rub a hole in the same hose. I had one made a little longer and routed it where it would not rub again along with several others. I am having a problem with it starts fine cold but after using it and letting it set it is hard to start. I am not getting the glow plug light to illuminate when turning the key to the left.

Hi Matt, which engine does your eMax22 have?

 

[MahindraMatt]

I don't know. Where is that info located?

Hi Matt, should be a label on top of the valve cover top of engine. You probably have either a Daedong or Mitsubishi. Mine is a Daedong.

 

[MahindraMatt]

I assume Daedong cause it says made in Korea.

On my Daedong, the glow plug relay is on the right side closer to the firewall under the fuse panel. There are two things that look like relays there. the back one(firewall side) is the glow plug relay. The one forward of it is the ECM. I had to replace both as the plug relay wires rubbed on a bolt or bracket(can't remember) and shorted out. Was having trouble with the plugs not operating correctly and eventually took out the ECM.
