Powerwise Charger Not Working

I was recently asked if I could take a look at a Powerwise 28115-G04 charger to see if I might be able to fix it. After some research, I found out that they now supply one circuit board that replaces both circuit boards in the charger. After I got the part replaced, it started working again.
