Bighorn 2017, while replacing my tv power inserter, I had to quite and leave rv due to emergency. When I returned to finish job today I had forgotten where the red, grey, and black coaxial cables go. Also while removing old inserter apparently a cable touched the motherboard causing me to lose lights on both sides of rv and to inserter. Changed fuse in panel and fuse by battery, still no power. Any tips would be greatly appreciated.
