Exterior; Removal And Installation Of Landing Light - Piper Dakota Maintenance Manual

The OIL warning light is controlled by an oil pressure sensor switch incorporated in the oil line and is
located at the firewall. The sensor switch activates when oil pressure is below 35 psi.
The ALT warning light is illuminated by current flowing from the bus bar to the alternator circuit. This
condition exists when the alternator is not operating properly and output is zero. During normal operation, the
alternator warning circuit isalso supplied with power from the top diode terminal. This current flows through a
5amp fuse to the resistor and diode creating a condition which does not allow the warning light to light.
The test button is used to check operation of the lights when the engine is running. The lights will work
when the engine is not running, if the master switch is turned on.
Oil pressure sensor and vacuum sensor switches are similar in
looks and size. Ensure correct unit is installed per parts catalog
part number and description
