water temp gauge only... light fine

started the sportline i recently acquired the other day and the temp gauge doesnt move at all..

the light flashes when key turned on stays on for a few seconds then goes out…

i left it running for ten mins but didnt want to run it too long as i couldnt see temp as gauge didnt move..

also fan didnt kick in… but i may not have run it long enough for that..

its the ecu fuel injected sportline cabby on a 91 just for reference

any help greatly appreciated

Dene

anyone?

ive replaced the sensor… nothing..

bridged the wires… nothing…

ran a live to fan.. that works..

but there is no live to fan or sensor, and fan isnt kicking in..

HELP!!!!

Fan is fuzed have you looked ?

Temp guage , pull wire off sender put some resistance in the wire , eg a 12v bulb or you will blow the guage and with ignition on earth the sender wire .

Guage should go to full ? If not guage or wiring is faulty , is fuel guage okay ? It shares the same voltage stabilizer .



    

ahh now then.. the fuel gauge also doesnt seem to work or move..

that the little black three prong thing on the back of the clocks?

any advice on sorting this?

many thanks for your reply mate..

Yes mate

Voltage stabilizer .

If both temp and fuel gauges don't work it is often a sign of a broken voltage stabilizer on the back of the clocks that supplies a constant 10V to them. Check the supply from it (3 pronged transistor held down with a screw) with a mutlimeter. If it is broken new ones can be bought from GSF or VW.
