testing Smiths telemetrix tempurature gauge
Hi Guys,
I have one of these:
http://www.demon-tweeks.co.uk/motorsport/gauges-auxiliary/smiths-telemetrix-electrical-water-temperature-gauge
and the sender for it:
http://www.demon-tweeks.co.uk/motorsport/gauge-sender-units/smiths-water-temperature-sender-for-telemetrix-and-international-gauges
I'm trying to test it but the wiring digram says you do the following
1 terminal to fused battery source
1 terminal to ground
1 terminal to sender
then sender to ground
Every time I try that the gauge maxes out.
Any ideas??

Sounds like your putting full battery voltage across the meter.
Should go like this from Battery +ve, Fuse, First Gauge Terminal, Second gauge terminal to sender terminal, sender body to earth (battery -ve)

If you disconnect terminal 1 (one to sender) then it should read zero, if you then short the terminal to ground it should read max

What is the resistance of the sender, it should read a resistance at room temp - so if it reads zero its possibly faulty?

Works fine now.
