Extra Gauges Fitted but wont light up??

[knight]

Am i missing something simple here.
Fitted the extra oil and volt gauges today and they work lovely......however no illumination.
Bulbs are all good as are the contacts.
Any ideas to remedy this would be most welcome.
Cheers Kev

remember the guages come in 2 types 4 pin and 6 pin connectors did you get matching guages and connectors?

That explains it then Jim....Bugger ...... Dont suppose you have a compatible one Jim, swap maybe ? . Cheers Kev

Kev you can operate both from either a 4 or 6 connector by adding or joining wires.

Thanks Jim, So are the other 2 wires hiding at the back of the dash somewhere ??

no the red connector will have either 6 wires or wires runnimg into it .

need to know exactly what set up you have before I can give you any further advice

Hi Jim, Sorry yes.
White connector block for 6 pins(only 4 wires running to it) and 6 pins on the gauge unit.
Hope that made sense

I imagine the 4 wires are
earth return
voltage (signal to voltmeter)
signal from oil sensor
live wire

the return and live will power the lights
so if I am correct there should a brown wire (earth) and a live wire which can be used to feed the 2 empty pins which should be the lights.

Now this is me only thinking about how the wiring should go to test my ideas you need to take the meter unit out disconnect and use a multimeter to check the connections or look up a wiring diagram .

That is what I would do anyway.
