code t334 and 339

been working on extreme intermitent issue where lift will code out with t334 and t339. went through troubleshooting steps, i.e check fuses pertaining to charge system. wires in x13 and x12 connectors. pre charge wires leading to lugs on main contactor and voltages at 1a1 and 2a1. not quite sure how to use my breakout box part number 7917299010. any help with that would be sweet because i cant find anything online on that aside from images and prices for another. so i say intermitent because i hooked up my breakout box to see if i couldnt somehow map it out and the code went away and then showed that my battery was low so i was able to move it and plug the lift in but as soon as i touched the connector x12 my codes came back. i checked all pins and found none loose. also my battery is showing full charge at 37.8 volts on a 36v system but my battery indicator is flashing like its below 20 % any ideas would be great

334 With main contactor activated, the capacitor voltage at power unit 2A1 is too low
339 Intermediate-circuit capacitor could not be charged correctly
