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 matter the state of charge of the batteries. What I’d like to know is how many amps is it putting out in this mode. And don’t tell me 55 because we all know that ain’t possible! ??
