Hi all, 1996 import wrx. The coolant temp guage does not work, i thought the single spade connector controlled the temp guage but fitted a new one and still not working. Going to remove clocks next but wanted to check that its defo the single spade controls and not the brown 2 pin sender. Also if the clocks are connected ok what is the wiring situation from sender to clocks? Is it one single wire? I did have a disc with wiring diagrams etc on but cant find it for love nor money!

Thanks in advance,

Spen

Yes it is the single terminal one. Personally as they aren't accurate I'd replace it with a Defi one with audible warning

If you earth the connection out it will shoot the needle to the top showing at least the wiring is good/there is a connection etc

Is the car running o.k, gets hot from the air vents etc, do you have a thermostat fitted etc, its not running cold all the time etc is it ????

Thanks for the rapid replies, will try earthing it out tomorrow. I just removed my clocks and as per older molested scoobs i found some horrors! I will add pics in a mo but what appears to be at the back of the temp guage there are 3 wires hanging, 2 of which are old speaker wires. Im guessing this was some kind of remoted coolant temperature?? Car gets hot and blows hot air would just be nice to know how hot!!

Does anyone know what these wires are for? and why they may stop my coolant temp guage working?

Those are defo NOT OE.

Can you not trace them to wherever they go?

My guess is that whoever had the car before fitted some sort of extra sender and used the temperature gauge to read it.

They may be shorted out at the other end, causing the gauge to read zero.

They are just hanging loose but the shorting was my thought! Will remove in the morning and see how it goes!

Trace them back, see what, if anything, they are attached to?

fieldy1978

No they don't attach to anything, there attached to the clocks then are just cut! I reckon they fed a pod!

Can you UNsolder them?

fieldy1978

They were attached by 3 screw terminals! Looks like defo for remoting! Still not working, tried earthing connector and nothing! Thinking the guage may be dead!

It's not impossible to swap the gauge for a working one from another set of instruments, and the early ones aren't dear on ebay.

Ok cool it's simple enough to open the clocks up then?

yeah clock open up real easy. sounds like that duff wiring has damaged the needle.

Clocks open up easily, the gauge will be bolted in, usually the bolts carry the current.

While you have them open, do yourself a favour and swap out all the illumination bulbs for new ones, plus check ALL the wiring tracks for cracks, burning etc.

fieldy1978

Ok thanks, yeah I will check tracks arnt damaged to guage but I think that loose wiring at back killed it! And yeah defo a good call on the bulbs! Will let you know how I get on!
