Temperature And Fuel Gauges; Flasher Unit - Triumph Spitfire MK3 Handbook

Temperature and Fuel Gauges

A temperature indicator, comprising a transmitter and gauge
unit operates on a 10 volts system controlled by a voltage
stabiliser.
The voltage stabiliser is attached by a screw to the rear of the
speedometer, and provides a constant 10 volts supply to a fuel
gauge and tank unit.
Flasher Unit (Fig. 56)
The flasher unit mounted in a socket attached to the bulkhead
below the facia contains an actuating wire which heats and cools
alternately to operate a set of contacts. The contacts control the
current supply to the selected flasher lamps. A secondary set of
contacts controls the flasher warning light which operates when
the system is functioning correctly. A defective unit must be
renewed. Renewal is effected by pulling the defective unit from
the socket and inserting a replacement.
