B1B Keven Posted July 15, 2011 Report Share Posted July 15, 2011 I wired it up as per the instructions, pulled the flashers on and I have 3 of 4 lights working. No passenger side rear. I switched wires at the rear bumper and now the there is no drivers side rear, but the passenger side rear works. Could it be a bad contact inside the unit? The black wire coming out of the unit doesn't appear to be working. Quote Link to comment Share on other sites More sharing options...
Young Ed Posted July 15, 2011 Report Share Posted July 15, 2011 Check for power with a test light at that black wire coming out of the unit. If there's nothing there then yes I'd say something is wrong internally. Is this a new 900 or something you bought used? Quote Link to comment Share on other sites More sharing options...

Broken rivet on the circuit board. A little solder and it works perfectly. Quote Link to comment Share on other sites More sharing options...
