General

See Controls and Indicators → Instruments: Lightning Models → Dash Panel: Lightning Models (XB9SX shown) . The dash panel has six indicator lamps.

The green turn signal indicator lamp (1) flashes when the turn signals are activated.
The green neutral indicator lamp (2) illuminates when the transmission is in neutral gear.
The blue high beam indicator lamp (3) illuminates when the headlamp high beam is on.
The red oil pressure indicator lamp (5) illuminates when oil is not circulating through the engine.

NOTE

The oil pressure indicator indicator lamp will illuminate when the ignition is turned on prior to starting engine. With engine running, the oil pressure indicator lamp should be off when engine speed is above idle.

See Controls and Indicators → Fuel Injection: Lightning Models for a description of the remaining lamps.

Oil Pressure Lamp Operation

Conditions that could cause the red oil pressure indicator lamp to illuminate during operation include:

Empty oil tank, incorrect oil level or diluted oil (at speeds above idle).
Oil feed line clogged with ice and sludge, preventing oil circulation (in freezing weather).
Grounded oil signal switch wire.
Faulty oil pressure switch.
Damaged or improperly installed check valve.

NOTICE

If the oil pressure indicator lamp remains lit, always check the oil supply first. If the oil supply is normal and the lamp is still lit, stop the engine at once and do not ride further until the trouble is located and the necessary repairs are made. Failure to do so may result in engine damage. (00157a)

Improper oil pump operation.

If the oil pressure indicator lamp illuminates during operation:

Stop the engine immediately and check the oil level.
Add recommended oil as required until proper level is achieved.

If the oil pressure indicator lamp illuminates during operation despite proper oil level:

Stop the engine immediately and do not ride further until the necessary repairs are made. See a Buell dealer.
