Focus MK2 Third Brake Light

452 Views 1 Reply 2 Participants Last post by  R.S.LOGAN
I bought Ford focus 2009 TDCI ST-Wagon for about year ago and since than i have noticed when vehicle is running the voltage is very unstable (13.9v-15.2v)
Ford dealer says its normal.

I also noticed ignition fuse keep blowing especially when the trunk is not properly closed.

But the main problem now is my third brake light doesn't have enough power (ampere), so it doesn't light up . I am getting 12V from wiring harness! By connecting third light direct to 12v battery it works fine.

Left and right brake lights are also dimmed after i had problem with third light.

I appreciate for any help i can get....
