Ok, this forum engine wont let me upload ipad screenshots anymore![Frown :( :(](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
CB76 goes to the brake switches then to S4, the main light switch. The output of S4 goes 3 places.
1. Pin 86 on relay K10.
2. Inter-vehicle connector
3. Trailer connector
A short along any of those 3 lines will cause CB76 to trip.
You jumped power directly to the K10 socket pin 86 and it burnt the trace to pin 86? That tells me you have a short back down that pathway toward the S4 output or the path to the inter vehicle and trailer plugs...
