In this video, Barry at DIY Golf Cart demonstrates some common fixes on both a DPI 36 and 48-volt battery charger. Barry starts off by changing out the DC cord on the chargers before discussing some of the common problems to look for when a charger isn't charging correctly.

If multiple fix attempts still result in a dead end, Barry indicates the control board may be the problem. He then demonstrates how to replace and mount a new board. Barry discusses battery charger modes and what they mean. Differentiating between charging modes is essential to ensure proper charging.

Finally, Barry discusses flashing indicator lights that specify problems within the charger that must be addressed within the owner's manual.
