Question about 1983 Ford Econoline
The temp gauge on my ford econovan is not working, i replaced the temp switch on the thermostat and it still dosent work, i also earthed the wire going onto the switch an the gauge goes up so the wiring is ok.. anybody got any ideas??
Sounds like you have installed a 'over-temperature switch' type sender unit- this type of sensor is only meant to control an over-temperature alarm indicator lamp that is either 'on' or 'off'.
The temperature gauge requires a 'variable resistance type' temperarure sensor to control the meter deflection.
When cold the temperature sensor is of high resistance, hence less meter deflection;
when hot temperature sensor is of low resistance, hence more meter deflection.
You need to procure a matching sensor to suit the type of gauge installed.
Is it possible you have connected to the temperature wrong temperature sensor? - most vehicles are fitted with both a gauge type (variable resistance) sensor to drive the temperature gauge, as well as a switch type (on or off) sensor to drive the overtemp indicator light.
