Do the circuit troubleshooting in that area with a conventional analog VOM.. Continuity with a DVM could be misleading. Most ANT/RF coils have a low resistance. Look for ground to chassis via rivets, solder them to the chassis using an active flux and an iron with a large copper bit (bolt)... GL  chas
