E-Z-GO Powerwise Charger Troubleshoot and Repair Guide

There doesn't seem to be a day that goes by at RMI Golf Carts that we don't receive phone calls or emails on the topic of battery chargers. Many times folks ask "do you guys sell chargers"? The answer is of course "yes"! But like we tell everyone that calls, more than likely you don't need to buy a new charger. Many people are shocked to know that most of the time they can be repaired.

Once this has been established, the next question is “How do I determine if it’s bad”, and "I’m pretty handy, what parts do I need"!!

So, we’ve decided to put together a "How to" video on repairing the E-Z-GO Powerwise Charger. This is the charger that works on all E-Z-GO PDS 36 volt carts. It seems to be the most popular charger out, and it’s the one we see the most.

Did you check the end of the Powerwise charger handle?

More often than not the issue is with the charger handle. Inside the charger handle there's a little clip. These clips wear and get pushed out of place. Pull the clip back out, so that it is grounded to the post.

Did you check the charger cord?

People have a tendency to yank the cord out when they’re done charging, this can damage it. With power supply plugged in, lift up on the cord rotate it different directions to see if the charger comes on. If the charger doesn’t come on, then you have a bad connection somewhere else.

Did you check the fuse on the Powerwise charger?

Unplug the charger. Use the voltmeter and ground it to the screw next to the fuse, and press the other end to the opposite side of the fuss. If it was a bad fuse you voltmeter wouldn’t buzz or beep.

Ground the heatsink board. With the other wand, touch each diode separately. If any of the diodes beep or buzz, then all of the diodes need to be replaced. The part number for the Powerwise replacement diodes is 18488G1.
