Hello good people,
Does anyone know the voltage for the LED Warning lights on the dash?  I cannot find this information anywhere.
I am having trouble with my battery light not working.  Instrument cluster out and I'm currently repairing it with Epoxy and have hard wired the LED instrument illuminators - which so far is looking good.
Thank you and have a lovely day.
Katherine.

Check the little blue wire ring terminal at the alternator, this is for the charge warning. It connects inside the engine bay junction box.

Yes thanks, I've already done that.
it could be the altenator brushes but I've only had that altenator for 6 years or so.

1.2 volts comes to mind for oil and battery warning lights
