Im going to get right to the point.
(i did the blinker mod by the way so please chime in if you think that has an effect on this)
Trailer hooked up to truck.
truck lights OFF
(trailer) Blinkers, and brake lights work
With truck Brake and blinker on, The trailer lights blink opposite of the truck. (left truck, right trailer and vise versa)
Truck Lights ON
Blinker, Brake, brake and blinker
The trailer lights will just blink left, right, left, right, left, right... you get the point.
Would a bad ground be the cause of this? or do you think its the blinker mod that would cause this. I havent pulled a trailer since ive done the mod. But the last time i pulled my boat, atv trailer and ice shanty they all worked great
