I was watching the RedWings game on the NHL channel (through Sling) and the electric advertising on the boards was showing a YouTube TV ad touting thier NHL coverage. I got excited because I thought maybe they finally carried it but it still looks like they don't. 😞

>I troubleshooting this rear light for my golf cart. The wires running to it got cut a few years ago and this weekend I decided to finally fix it. I butt ended the three wires but the light still didn't work so I took it apart. Upon inspection there was a broken diode (1N4007). I replaced and it still didn't work. I then tested the other diode and the two resistors, all test good. If I hook it to the golf cart (12v) I can see the LEDs very dimly light up.
>The way this is hooked up is that both white and red are positive and black is negative. I believe these are made to support a brake light and turn light or parking light and turn. I don't have turn signals so they are setup just to be parking (marking) lights.
>I'm a beginner in electronics but enjoy fixing stuff so go easy. I thought that diodes always went from positive to negative. The diode on black seems backwards to me. I did take apart the other working light and it is setup the same.
>I cannot get this to light up with my bench power supply. Settings are 12v and 2amps. If I take the board out and hook it to the wire harness I can see very dim red lights. I'm not sure I'm using my power supply correctly but I didn't want to crank the amp setting and blow something up.
>Any troubleshooting help would be appreciated. Note, I'm heading out so I won't be able to reply for a bit. Thanks!
What I found is that everone was correct in thinking the white wire is ground. I had been testing the cart side in a dark tight corner. Decided to move stuff around and take a closer look. Seems like the installer left me a present in the form of swapping wires at the connector.
Lesson here folks, do complete troubleshooting, make no assumptions other than assume the last person may have done it wrong!!
notice cart side black becomes white, white becomes red, red becomes black
