My Powerwise Industrial charger (Model 28115G01) has developed a problem. It has been working about 7 years with no problem. I know the charger is bad because I have another more modern Powerwise 2 works. I got a chance to review some of the advice I have offered on this post. My charger suddenly developed low output current and a more than normal hum when it turns on. First thing I checked was the capacitor. It was badly corroded and rusted but it measured 19.8 Microfarads. A substitute capacitor did not change anything. Both diodes checked good. The only abnormal indication was the secondary of the transformer got warm after a few minutes of operation. Neither diode was more than warm to the touch. This charger also has a circuit board mounted in front of the diode heat sink may be the problem. My GUESS is the transformer is bad. I am not going to replace it. I did make one observation with the capacitor disconnected. The charger would not hum when powered up and plugged into cart.
