WFCO WF-8955 amps in absorption mode
I have a WFCO-8955 (55 amp) that absolutely will not go into bulk mode even though it’s a 3 stage converter. Not sure if it’s inadequate wiring or an inadequate converter. It’s always 13.6-13.8 no mat...

Something else to add, if you "never" see the voltage drop down into the 13.25 volt range, (float mode) sooner or later being at 13.6V (standard charge) "all" the time is a sign you are going to boil out the battery in short order. Check the electrolyte level often to not go below the plates.
If you are camping on shore power for 4 to 5 days and the voltage never drops to 13.25 V, there is a problem. Maybe the WFCO, maybe a bad cell in the battery. This is a separate issue from not going into boost mode.
WFCO's as they age are real good battery killers and other devices in the camper. They seem to die 3 ways. Way high voltage, real low voltage or just plain die and do not work. The first two ways you may not notice until other damage is done. At least when they die totally, they do not kill something else in the process.
