Dash light help
 

Hello, I’m looking for technical help.

I’ve posted this in general and the 912 section. So if there is a rule against cross posting please delete one of the threads.

I am working on a 1967 912.
The wiring harness for the gauge lights have been melted and I’m in the process fixing it.

I have some questions about the warning lights.

The Speedo has a green indicator light in it.
The best I can figure out, it is supposed to come on when the parking lights are on, and then goes off once you turn the headlights on.

The Tach has a blue indicator light in it.
That should come on when you have the High beam head lights on.

The Temp gauge has 3 indicator lights.
Orange, green, white.
Best I can figure out one is for the hand brake, low oil pressure, low voltage.
But I don’t know what color is for what problem.

The Fuel gauge has a red indicator light
Is that supposed to come on when the tank is almost empty?

Thank you in advance for your help and knowledge.
