I have a 2008 JD 2720 that I recently bought with 150 hours on it. When I start it cold, there is a red light just above the fuel gauge that comes on for about 5 seconds just after it starts. It appears to have like a pair of circles in it, that makes me "guess" it might be for the glow plugs or something, but my owners manual mentions NOTHING about a red light like this on the dash. Its weird that the book is clueless.
Does anyone know what the light is for or what it means?
Thanks
Below is the 2720 owners manual section on the instrument panel. Does this match what you are seeing?
Using Instrument Panel
MX35669
A - Park Brake Light - This light should illuminate when the park brake is set and locked.
B - Engine Coolant Temperature Light - This light will turn on when the engine coolant is approaching a dangerously hot temperature. If this light turns on during operation, remove load on machine immediately. Reduce engine to idle speed and check for something blocking air flow to the radiator and check engine coolant level. If light stays on after cleaning grille, stop engine.
C - Alternator/Battery Charging Light - This light will turn on when the ignition key is in the ON position and the engine is not running. If this light turns on while the engine is running, the alternator output is too low. Move the throttle lever to the full throttle position. Stop the engine if light remains on.
D - Engine Oil Pressure Light - This light will turn on when the ignition key is in the ON position and the engine is not running. If this light turns on while the engine is running, engine oil pressure is too low. Stop engine.
E - MFWD Light - This light will turn on when Mechanical Front Wheel Drive (MFWD) is activated.
F -Warning Flasher/Turn Signal Indicator Light - This indicator light will turn on and flash when the light switch is turned to the warning flasher lights ON position, the headlights, taillights, and warning flasher lights ON position or the turn signal switch is moved to the left hand turn position.
G -Warning Flasher/Turn Signal Indicator Light - This indicator light will turn on and flash when the light switch is turned to the warning flasher lights ON position, the headlights, taillights, and warning flasher lights ON position or the turn signal switch is moved to the right hand turn position.
H - PTO Engaged Light - This light will illuminate when the PTO is engaged.
I - Glow Plug Light - This light will illuminate for 15 seconds when the key is turned to the ON or start position.
J - Fuel Gauge - Shows approximately how much fuel is in the fuel tank.
K - Tachometer - Shows engine speed. Engine speed is shown in 100’s. Example: If indicator is pointing at 20 (20 x 100 = 2000 RPM). Note the special marker labeled RATED. With the indicator pointing at the RATED marker, this is the proper engine speed for the 540 RPM Power Take Off (PTO).
L - Hour Meter - Shows total number of accumulated running hours at rated speed. Use the hour meter as a guide when servicing various components of this machine.
