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

Battery

Use a volt–ohm meter to measure the voltage between
the battery terminals.
If the voltage is less than 12.3 Volts D.C., the battery
should be charged.
NOTE: Regulated voltage will increase to approximately
13.5 Volts when the engine is running.

Indicator Lights and Gauges

Oil Pressure Light
Oil pressure lamp should come on when the ignition key
switch is in the "RUN" position with the engine not run-
ning or if the oil pressure switch closes during operation
– oil pressure below 7 psi (0.5 kg/cm2).Test the lamp by
disconnecting the wires and applying 12 V.D.C. between
the lamp wiring terminals.
Amp Light
(Liquid Cooled Engines)
The amp 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 V.D.C. between the lamp wiring
terminals.
Electrical System (Rev. G)
Glow Light (Diesel Engine)
The glow light should be on when the glow switch is "ON"
or the ignition key switch is in the "START" position. Test
the lamp by disconnecting the wires and applying 12
V.D.C. 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 hourmeter should operate as 12 V.D.C. is applied
between the terminals.
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.
