Battery; Indicator Lights And Gauges - Toro Workman 3000 Series Service Manual

Battery

Use a digital multi meter to measure the voltage between
the battery terminals.
If the voltage is less than 12.3 Volts DC, the battery
should be charged.
NOTE: Regulated battery voltage will increase to
approximately 13.5 Volts when the engine is running.

Indicator Lights and Gauges

Oil Pressure Light
The oil pressure lamp should come on when the ignition
key switch is in the "RUN" position with the engine not
running or if the oil pressure switch closes during opera-
tion – oil pressure below 7 psi (0.5 kg/cm
by disconnecting the wires and applying 12 VDC. be-
tween the lamp wiring terminals.
Charging Light (Liquid Cooled Engines)
The charging light should come on when the ignition key
switch is in the "RUN" position with the engine not run-
ning or if the charging circuit is not operating properly
during operation. Test the lamp by disconnecting the
wires and applying 12 VDC. between the lamp wiring ter-
minals.
Glow Light (Diesel Engine)
The glow light should be on when the ignition key switch
is in the "RUN" position and the glow switch is "ON". Test
the lamp by disconnecting the wires and applying 12
VDC. between the lamp wiring terminals.
Hourmeter
Test the hourmeter by connecting a 12 volt battery so the
positive (+) battery terminal is connected to the positive
terminal on the hourmeter. Connect the negative (–) bat-
tery terminal to the negative (–) terminal on the hourmet-
er. The hour meter should move 1/10 of an hour in six
minutes as 12 VDC. is applied between the terminals.
Electrical System
Temperature Gauge and Fuel Level Gauge
To test a gauge, use a commercial gauge tester. If a com-
mercial gauge tester is not available, substitute a new
gauge or test the sending unit.
