Sounds like a bad earth somewhere.

I'd check all the bulbs on the rear for a good clean contact and make look for all the earth points on the circuit and check for continuity/corrosion etc.

Another try is to remove the bulbs one by one and see in which circuit the failure is located, then when you found out just check the complete wiring of faulty circuit.

CHECKED ALL CONNECTIONS AND GROUNDS, ALL GOOD, WORKED FOR A SHORT TIME. CAN HEAR SOMETHING JUST UNDER THE AIR CLEANER ASSEMBLY TRYING TO RUN, THEN BLOWS CIRCUIT BREAKER. THIS ONLY HAPPENS WHEN PARK OR HEADLAMPS ARE ON...ANY IDEAS. SERVICE DISC DO NOT SHOW ANYTHING ON #3 FUSE LEADING TO THE ENGINE COMPARTMENT....
