Most Important Warning Lights

Engine Overheating

Common causes

  • Low coolant level
  • Clogged radiator fins
  • Faulty thermostat or water pump

What to do

Stop the Massey GC immediately and allow the engine to cool. Check coolant level and radiator debris. Replace thermostat if stuck closed.

Loss of Oil Pressure

Common causes

  • Low oil level
  • Oil filter plugging
  • Oil pump failure

What to do

Shut down the engine on your GC right away. Check oil dipstick and add oil if needed. Inspect for leaks and replace oil filter at service.

Charging System Failure

Common causes

  • Loose alternator belt
  • Faulty alternator
  • Blown fuse or bad connection

What to do

On your GC, check belt tension and wiring connections. If light stays on, have the alternator tested and replaced if defective.

Hydraulic System Issue

Common causes

  • Low hydraulic fluid
  • Contaminated fluid
  • Leaking hose or seal

What to do

Inspect hydraulic oil level on your GC and top off with correct spec. Locate and repair any leaks before continuing work.

Transmission Overheat

Common causes

  • Prolonged heavy load
  • Low transmission fluid
  • Clogged cooler

What to do

Reduce load and allow your GC's transmission to cool in neutral. Check fluid level and condition; clean cooler fins if needed.

Frequently Asked Questions

Why is the check engine light on intermittently on my Massey GC?

Intermittent light often indicates a loose connector, low fuel quality, or a sensor glitch. Try tightening the fuel cap and cleaning battery connections; if it persists, visit a dealer.

What should I do if the hydraulic light comes on while using the loader?

Stop loader operation immediately and check the hydraulic oil level in the sight glass. Low fluid can cause pump damage; add approved hydraulic oil to the full mark.

How long should I wait for the glow plug light to turn off in cold weather?

Typically 5-15 seconds depending on temperature. Do not crank the engine until the amber glow plug light goes out on your GC.

Can I drive with the transmission temperature light on?

No. Continuous operation will damage the hydrostatic transmission. Stop, let it cool in neutral, and check fluid level before proceeding.

Why does my parking brake light stay on even after releasing the lever?

The switch may be stuck or the brake not fully disengaged. Verify the lever returns fully and the linkage is free. If light remains, adjust or replace the switch.

What does it mean when the work light indicator flashes?

A fast flash usually indicates a bulb failure or short circuit in the work light circuit. Check bulbs and wiring for damage on your GC.
