Coolant level sensor wiring
One more about the coolant warning light.
My light is on for a week now. Coolant level is at max and the wiper fluid full.
Checked the 12V (2x on the large pin and 1x on the smaler pin) on the control module and hot-wired the cooling fan. All normal, light still on.
Now I saw that some idiot disconnected the wiring from the coolant level sensor and twisted it together!!
Is the circuit, for normal level, open or closed?
