Gauges
Voltmeter
The voltmeter is connected to the fuel run/stop solenoid output. If the voltmeter does not
indicate in the run position, this indicates a problem with the solenoid circuit. A battery voltage
reading of approximately 14 volts on a 12 volt system (28 volts on a 24 volt system) while the
engine is running indicates the battery is charging properly.
Tachometer
The tachometer indicates engine RPM using a frequency signal derived from the engine. This
signal may be provided by an alternator frequency tap, proximity switch. An optional
amplifier/divider can be added for use with a magnetic pickup.
Note
If the alternator is not excited (not charging),
no frequency is generated and the tachometer will indicate 0 RPM.
The tachometer must be calibrated to the engine using standard procedures (see
Tachometer
Calibration Instructions
for details).
Oil Pressure Gauge
The gauge measures oil pressure with a resistance sender on the engine referenced to ground.
When a sender/switch combination is used on the engine, the marking
G
generally indicates the
gauge terminal. The gauge expects a low resistance for low pressure and a higher resistance for
higher pressure. If a powered gauge is not connected to the sender, the gauge will read full
scale (pegged). A defective sender or shorting the gauge input to ground will cause the gauge
to read no pressure. When using sender/switch combinations, swapping the
WK
and
G
terminal
prevents the gauge from working and may cause unintended shutdowns.
Warning!
Low oil pressure is an indication of engine wear,
not an accurate indication of low oil level.
Note
Senders and gauges must be matched to indicate correctly.
Most senders are grounded through the sender body.
Do not use insulating sealant (i.e. Teflon tape) when installing senders.
Temperature Gauge
The gauge measures engine temperature with a resistance sender on the engine referenced to
ground. When a sender/switch combination is used on the engine, the marking
G
generally
indicates the gauge terminal. The gauge expects a high resistance for low temperatures and a
lower resistance for higher temperatures. If the gauge is not connected to the sender, the will be
on read the minimum reading. A defective sender or shorting the gauge input to ground will
cause the gauge to read full scale (pegged). When using sender/switch combinations, swapping
the
WK
and
G
terminal prevents the gauge from working and may cause unintended shutdowns.
