Electrical starting slow crank no start

“Just stopped” like turning the key off, or stopped like it was running out of fuel?
A bad battery or frame wiring connection could act like turning tractor off and cause weak cranking.

Stopped like turning key off.

How long was it running? What is the ambient temperature? When you first started, did it spin over normally or slow?

Started normal Ambient air temperature 10° c. With a battery boost still cranked slowly.

Weak battery?... Are all connection clean and tight..... If battery voltage drops below about 9-10 volts while cranking, battery is probably on the way out.... Extreme cold can cause havoc with a weak battery... If you add "jump box" or jump battery does it crank OK?

Still crank slow with a jump box or jump battery.

Still crank slow with a jump box or jump battery.

Check the terminals on the electrical cables and the battery ground.

No start slow to crank. Electrical problems?
Where to start? Where to find an electrical wiring diagram
Mahindra 2816 please.
Ground issue common?
Tractor was running and going and just stopped. Wouldn't start. I thought it was seized . 3 cylinder Mitsubishi diesel.

Update- tractor is back on its wheels. I cleaned all ground connections. That solved 80% of the problems I removed starter motor and tested it. Good result. Why this seem to be an intermittent starting problem is because the alternator belt was slipping. Barry would charge up sometimes. Sometimes it wouldn't. It won't be your bill. Battery is charged up and staying that way. I also removed a setup. LED bright lights had an unusual draw on the electrical system.
Thank you for everyone's suggestions.
