Thank you ,
I have a better understanding of the system now . And seemingly both sides have shorts. I put a new 10amp fuse in and blew it. I Got two signal clicks off the left ( good side) , then she went. I’ll tone out wiring soon , unplug lamp holders and go from there. All I have is my electrical back Round, which is why I started with that. The Mechanical will come with time.
(Both brakes and parking lights share the same bulbs.)
thank you for your help, I’ll update you as I trouble shoot. Hopefully it’ll help someone else in the future.
