         DESCRIPTION & OPERATION

         Instrument cluster for most models includes speedometer, fuel
gauge and temperature gauge. Optional instruments include clock,
tachometer, voltmeter and oil temperature gauge. See Figs. 3.
         Printed circuit provides voltage to gauges. A voltage
regulator attached to printed circuit controls voltage to fuel and
temperature gauges. Most warning lights are a Light Emitting Diode
(LED). To replace diode, pull from printed circuit socket.

         TESTING

         VOLTAGE REGULATOR TEST

         1) If only one gauge is inoperative, regulator is not
defective. Remove instrument cluster trim. Remove combination gauge.
Connect positive (+) lead of voltmeter between combination gauge
terminals No. 1 and 2. See Fig. 1. Turn ignition on. If battery
voltage is present, go to next step. If battery voltage is not
present, repair wiring harness or replace voltage regulator as
necessary.
         2) Turn ignition off. Install combination gauge. Remove
speedometer. Connect positive (+) lead of voltmeter to terminal No 1
of voltage regulator. See Fig. 2. Connect voltmeter negative (-) lead
to terminal No. 2. Turn ignition on. Meter reading should be 9.5-10.5
volts. If voltage is incorrect, replace printed circuit or voltage
regulator.

         FUEL & TEMPERATURE GAUGE TEST

NOTE:    Volkswagen Tester (VW 1301) is required for resistance
         tests. Tester settings are numerical. Settings do not
         indicate resistance in ohms. Manufacturer does not supply
         resistance values in ohms.

         1) Disconnect wire from fuel tank or temperature sending
unit. Connect VW Tester (VW 1301) between wire and ground. Turn
ignition on and allow 2 minutes for gauge reading to stabilize. Use
FUEL GAUGE TESTING or TEMPERATURE GAUGE TESTING table to compare gauge
reading. Gauge should be within one pointer width of specification.
         2) If gauge needle does not move, check continuity between
sender wire and gauge. If needle moves but does not match
specifications, replace gauge. If gauge works correctly with tester
but not sending unit, replace sending unit.

         REMOVAL & INSTALLATION

CAUTION: DO NOT damage printed circuit when installing instruments.

         INSTRUMENT CLUSTER

         Removal & Installation
         1) Obtain radio code. Disconnect negative battery cable.
Remove steering wheel only when removing complete instrument cluster
housing. Remove trim screw caps and screws located on lower part of
instrument cluster trim. Remove instrument cluster trim.
         2) Remove trip odometer reset button. Remove trim cover
retaining screws. Remove trim cover from instrument cluster. Remove
instrument cluster housing retaining screws. Pull instrument cluster
from dash panel. Disconnect multi-point connector, MFI vacuum hose (if
equipped) and speedometer drive cable. Remove instrument cluster
housing.

NOTE:    All components in instrument cluster, except for printed
         circuit, can be removed from front, without removing
         complete instrument cluster housing.

         3) Disconnect speedometer cable, remove mounting screws and
pull speedometer from housing. Squeeze locating pins on other
instruments and pull from housing. To install, reverse removal
procedure.
