I am replacing the MBA in my WFCO WF-8955PEC power center with a Boondocker BD 1255MBA 55 amp, 4 stage MBA. No instructions came with the Boondocker unit however, I believe it is the same as the "Powermax" PCMB-55-MBA. I found some instructions on INET for Powermax, but they are very poorly written and make little sense. Installing the circuit board and associated wiring is a breeze, but the instructions on how/when to adjust the fixed voltage circuit switch/potentiometer are a joke.. they jump all over.. Has anyone installed this particular Boondocker board and did you even bother to adjust the "fixed voltage"? or maybe even a better question, did you find better instructions on how to do it?
