Good day
I recently acquired a beautiful giant beast, but recently something odd started to happen. When ever I turn on either turn signal, both reverse flash with it. At first I thought maybe crossed wire somewhere, but it doesn't happen with the brake lights. So I suspect some component somewhere is having some issues, but I'm not sure where to begin. I've got a repair manual on the way, but it won't arrive for a couple more weeks.
Does anyone have any suggestions?
Thanks

 

Check for correct bulbs. Check the bulbs for crossed filaments. Check grounds

 

Thanks TVLynn. Ground connections was the solution.
Once I managed to find the ground wires, I discovered that they are super old and brittle, they literally broke apart. After fixing them up, the lights worked perfectly and are bright again! Not so dim that you can't see them in daylight.


On a side note: Before I had a chance to repair, I took the reverse bulbs out so I wouldn't get pulled over. Don't really use them in traffic. When I put them back in before the repair, I was unable to replicate the reverse light problem.
