Hi,

I'm getting slight cross contamination between tail lights and indicators on both rear lights.

I have eliminated the lamp units (by removing them) and the plastic plugs and the earth is perfect.

Putting a multimeter on the plug supply wires shows that the problem must be further back/ supply- electronic module???

TESTING ON OFFSIDE=

With brake on -Green/yellow wire (brake wire) ONLY 6.7v
Lights on- Yellow/black (tail light wire) 11.7V and green/yellow wire 6v
Indicator on- Blue wire (indic wire) 11.79v AND green yellow wire 5.7v- WHICH MUST BE INCORRECT.

Car battery is good- no problem starting up etc, and test results the same with engine running.

Any ideas?

Many thanks,

John

Dodgy earth down the line..?

Not sure.

I ran an separate 'good' earth from the boot catch to the multi-meter and got the same results.
