annoying lights problem

[kikkegek]

I have a real annoying lights problem.

When I have my headlights on, everything is fine.

As soon as I turn on my blinker to the left or right the reverselight and blinker start turning on and off and the dashboardlights start blinking too.

I looked at the electrics and it seems that the brake, blinkers and sidemarkers al seem to share ground connection, which I dont understand.

can somebody please help me fix this.

The funny thing is, as soon as I uncrew the complete right rear brake/blinker unit, the problem is gone.

I already tried repacking the ground wires that are all connected together behind the unit.

And then when I screw the unit back in, it'l be fine for some time and then out of the blue "the christmas light act" comes back again.

please help!
