Help with Converter problem, please.
Brought DW home from hospital Friday after her TKR. All went well, now PT. Had a bad storm while at the hospital and lost shore power. Now it appears that I have lost 12V out from the converter, no 12...

The first 15AMP Circuit breaker you see on the 120VAC Distribution Panel is usually the circuit breaker for the WF8900 series converter.
Make sure it is RESET and providing 120VAC to the WF8900 series converter before you can call it bad.
Physically flip the circuit breaker and make sure it is reset... They look reset sometimes and are not...
As you can see the DC OUT from the WF8900 series converter and the Battery Leads both feed the same point on the 12VDC side of the Power Distribution Panel.
The WF8900 series Converter when plugged into the shore power connection should put out 13.6VDC at all times unless it is in a smart mode charging mode. I could never get my WF8945 converter charger to go into smart mode charging so I added a PD9260C Converter down the chain as shown in this diagram. I can use either converter now by just flipping the correct 120VAC circuit breaker.
Another NOTE: you mentioned you measured for DC VOLTAGES across the NEG and POS lugs on the fuse board. You will read 0VDC if the one of the two HIGH CURRENT REVERSE POLARITY are not making contact with its socket or BLOWN and the Charged up Battery leads have been disconnected. You may need to re-measure the leads that come from the WF8955 unit to be sure if it is putting out 13.6VDC when plugged into shore power and the 15AMP circuit breaker for the converter is ON
