In this video I'm going to talk about how to use an electrical diode on a 12 volt system to prevent electricty from flowing back through your system and reverse powering accessories.
I had this problem with my four way flashers. When I turned them on, they worked, but when I turned on either of my blinkers, all four lights also flashed! I added 2 electrical diodes to the directional wires and that stopped the power from cross feeding when it went through the flasher relay.
This will hopefully help you understand how to solve this problem if you have it on a 12 volt system!
This is an obscure video, but it was a problem I was having, so I hope it helps you!
