Hello guys. I just brought my boat home. All is fine except for the wiring on the trailer. All the lights work except for the passenger brake light. When i press the brake both sides light up fine however when i turn my lights on then press the brake the passenger side goes out. when i let go it comes back on. The driver side doesn't have a problem. I checked all the wiring,grounds and bulb. Can someone please help. I attached a diagram.

Ayuh,... I'd say you Missed something, somewhere...
Because, you've still got a Ground problem...

yup... as Bondo said you missed a bad ground... It may be in the light housing or on the trailer

Hey guys thanks for the help. Yes it was a ground. The light in question was grounded to a plastic piece that i mistook for metal. everything is up and running. Thanks for your help.

I forgot to tell you the best part. Get this, I have a certification in ac electricity. I know that dc is a little different but it still is embarrassing anyway. Lesson
"don't overlook the obvious." Thanks for the help
