Massey Ferguson 1635 temperature gauge not working fixed

This is a narrow troubleshooting clip for one specific fault: a Massey Ferguson 1635 temperature gauge acting up. The creator walks through diagnosing a suspected bad sending unit, then finds the real cause was a loose brass ground screw behind the dash gauge itself. Short and specific, useful mainly for owners chasing an erratic temp gauge after ruling out the sending unit and wiring.
