GENERAL INFORMATION—DODGE The automatic transmission push buttons and the
heater and/or air conditioning push buttons protrude through the
cluster but are not attached to it. The parking lever (automatic transmission sprag) and the temperature control lever also protrude through the cluster trim plate but are not attached to the cluster. |

GENERAL INFORMATION—DART The instrument cluster assembly, as shown in Figure 2 is assembled into the instrument panel. The cluster contains the speedometer, fuel gauge, temperature gauge, ignition switch, cigar lighter, alternator (ammeter); oil pressure warning light. The instruments and lamps are attached to a printed circuit (conductors) in the form of die cut, copper foil strips. The printed circuit completes the circuit to the fuel gauge, temperature gauge, voltage limiter (located inside of the gauge) and instrument lamps. The screws attaching the printed circuit to the cluster base serve as grounds for the instrument lamps and voltage limiter. With the exception of the leads to the alternator (ammeter), ignition switch cigar lighter all wiring to the cluster is connected through a plug type multi-connector to the printed circuit male connector pins on the printed circuit board which is attached to the back of the instrument cluster assembly. The female multi-connector is a push type with a master locator pin. |

1. BULK HEAD CONNECTOR
The wiring for the lights and engine compartment components
is attached to a bulk head wiring connector on the fire wall, as shown in Figure
3 below.
The bulkhead disconnect is inserted into the dash panel from
the passenger compartment side and is secured by four metal tabs. The mating
disconnects are connected on the engine compartment side of the dash panel.
The bulk head connector can be removed from the cowl panel by disconnecting the engine compartment connectors, depressing the four metal tabs with a fine blade screwdriver and pulling the connector from the dash panel.
2. GAUGE OPERATION
The fuel and temperature gauges are the thermal type.
The gauges operate on a principle of a constant voltage being
applied and are sensitive only to changes in fuel level or temperature.
Voltage Limiter—Dodge (fig. 1)
Constant voltage is provided through a voltage limiter mounted
on the back of the instrument cluster and is connected in parallel to the gauges
and provides the same regulated voltage to both gauges.
Voltage Limiter—Dart (Fig. 2)
Constant voltage is provided through a voltage limiter contained
inside the fuel gauge, and is connected in parallel to the fuel and temperature
gauges and provides the same regulated voltage to both gauges.
Tank Unit A float arm is hinged to allow the float to raise or lower dependent on the fuel level. The float connects to a variable resistance that provides a change in the resistance with any up or down motion of the float through a wiping contact in the gauge body, as shown in Figure 4. |
