The engine oil pressure switch is located on the engine near the oil filter
157 or Figure 158). The oil pressure switch is a normally closed switch that
opens with oil pressure.
On the Groundsmaster 3280-D (diesel engine), the oil pressure switch should
open at approximately 55 kPa (8 psi).
On the Groundsmaster 3320 (gasoline engine), the oil pressure switch should
open between 20 to 39 kPa (2.9 to 5.7 psi).
The oil pressure switch is connected to the oil pressure indicator light on the
control panel. If the switch opens while the engine is running (indicating low oil
pressure) the indicator light on the control panel illuminates.
