Gear Problem solved
 

On my 337H we solved the gear problem. The gear came down, doors stayed open ,breaker popped & no light. The "U" shaped plate on both gear legs broke loose. These stricker plates are located where the down lock & down lock switch slide in. The plate has a bolt at upper end which kept in from falling off, but the bonding broke loose to the gear leg. We ordered the factory bonding & re-bonded. I looked in parts manual, to give all the exact part number. It does not give part # or picture in my new $400 part manual I purchased last year.
