REMOVAL & INSTALLATION



A voltage stabilizer feeds a 10 V current to both the temperature gauges and the fuel gauge. Electrical malfunctions in these gauges must be checked with an ohmmeter, not a 12 V test light. If malfunctions occur simultaneously in all three of the gauges that are fed by the stabilizer, the stabilizer itself is probably malfunctioning. When replacing the voltage stabilizer, the new unit must fit in the same position as the old one. If the stabilizer is not located correctly in the dash, the voltage output may be altered.

1800 Series

The 1800 series Volvos are equipped with a tachometer, coolant temperature gauge, oil temperature gauge, speedometer (with odometer, tripmeter, and warning lamps), fuel gauge, oil pressure gauge, and clock. Each of these instruments must be removed separately.

When replacing an instrument, first disconnect the negative battery cable, then disconnect the electrical connectors at the back of the gauge. Remove the retaining nuts and attaching bracket and pull the instrument straight out of the dash.
