DESCRIPTION & OPERATION
All models have instrument cluster with speedometer, fuel
gauge and temperature gauge. Impulse models also have oil pressure
gauge and voltmeter. All gauges use variable resistance sending
units. A voltage regulator in cluster ensures readings stay constant
when charging voltage varies.
P’UP LS models have a combination meter assembly that
consists of a voltmeter and oil pressure gauge.
TESTING
VOLTAGE REGULATOR
P’UP & Trooper II
1) On P’UP models, regulator is built into fuel gauge. On
Trooper II models, regulator is mounted in different locations,
depending on instrument cluster arrangement. Remove gauge cluster and
measure resistance of regulator by connecting ohmmeter leads as
shown. See Figs. 1 and 2. Resistance should be 110 ohms.

2) To test regulator operation, connect battery positive
terminal to connector terminal No. 2 and battery negative terminal to
connector terminal No. 6. Connect voltmeter to connector terminal No.
6 and fuel gauge. Check voltage regulator output. Regulator output
voltage should be 7 volts. See Figs. 3 and 4.

FUEL GAUGE
Impulse
Connect ohmmeter to fuel gauge terminals. See Fig. 5.
Resistance between "IG" and "U" terminals should be about 260 ohms.
Resistance between "IG" and "E" terminals should be about 200 ohms.
Resistance between "U" and "E" terminals should be about 109 ohms. If
resistance is not as specified, replace gauge.

P’UP & Trooper II
Connect ohmmeter to fuel gauge terminals. Resistance should
be 25 ohms. See Figs. 6 and 7. If resistance is not as specified,
replace gauge.

FUEL GAUGE SENDING UNIT
Impulse
1) With sending unit removed from tank, connect positive
side of battery to fuel level sending unit terminal No. 5 and
negative side to terminal No. 3 of connector. Measure voltage between
terminals No. 1 and 3. See Fig. 8.
2) With float in empty position, voltage measured should be
about .6 volts. With float in full position, voltage should be about
3.5 volts. Float should be about 7.9" (200 mm) from inside edge of
sending unit for empty measurement and 2.5" (63 mm) for full
measurement.

P’UP & Trooper II
Connect ohmmeter to fuel tank sending unit. As float is
moved, resistance reading should change smoothly. Check resistance at
full position. Resistance should be 17 ohms. Resistance at 1/2
position should be 45 ohms. Resistance at empty position should be
120 ohms. If readings are not correct, replace sending unit. See
Fig. 9.

TEMPERATURE GAUGE
Impulse
Using an ohmmeter, check resistances across temperature
gauge terminals. See IMPULSE TEMPERATURE GAUGE RESISTANCE table. If
resistances are not correct, replace gauge. See Fig. 10.

P’UP
Using ohmmeter, measure resistance across terminals as
shown. See Fig. 11. Correct resistance is about 34 ohms. If
resistance is incorrect, replace gauge.

Trooper II
Using an ohmmeter, measure resistance between terminals on
temperature gauge. Temperature gauge resistance should be 25 ohms.
See Fig. 12.

TEMPERATURE SENDING UNIT
Measure resistance of sending unit after removing from
vehicle. Place sending unit in water and heat to specified
temperatures. If resistance is not to specification, replace sending
unit. See TEMPERATURE SENDING UNIT RESISTANCE table.
