allright thanks,
The weird thing is that it became worse over time
first, it worked like it should
then they wouldnt flash, only turn on until i switched them off,
and then the would only turn on one flash but wouldnt flash repeatedly, and now nothing.
But ill check main power wiring, i also searched here for a wiring diagram but couldnt find it, but i thought i'd seen it on these forums before.. Well i'll search some more.
I'll keep you guys updated.
