Frequently Asked Questions About Your New Golf Cart Battery Charger

Dear Pete, Hi, finally this week we got the charger. However; once plugged to both the outlet and to the golf cart no lights come up, is this normal? Batteries haven’t been charged in a while. Confused… Terrific… Glad to hear you finally received the charger. Though in order for these chargers or any new style charger to function they need to be able to pick up voltage from the cart. If the batteries are completely dead or near so the charger will not kick on. You will need to charge the batteries up individually with like an automotive style charger, two at a time if you have a 36 volt battery system, or even can do 3 at a time if you have a 48 volt system and a automotive style charger that allows you to toggle charge voltage like 6v, 8v, 12v, or 24v. Once the bank of batteries is at least 35-40v plug in the new charger and it should do its thing. Regardless of how you do it the battery bank needs to be charged up enough for the new golf cart battery charger to know it is actually hooked up to a battery bank comparable the operating voltage of the golf cart charger you purchased. Once this is achieved should be able to use the new charger as intended. To get the most out of your batteries… Always charge your batteries back up after use and before storing. This is also the time to check the water level in traditional lead acid batteries. (After they are completely charged.) Pete
Pete… Super fast shipping thanks, Question? I received the new DPI 36 volt golf cart battery charger this morning. I started charging the batteries and everything was working fine. I came back to check if it had finished charging and the charger was hot, the amp meter was still showing close to 20 amps. I checked the battery volts with a volt meter and it showed 45 volts. I unplugged the charger from the wall outlet and disconnected the plug from the cart. I again checked the voltage and it was still at 45 volts. Is there something wrong with the charger or is this normal? These are new batteries and I don t want them ruined.   Yes sir…. All seems to be fine… These types of chargers do generate heat. Really any device that is passing and converting current (electricity) thru it will do so. That’s why they are made with Aluminum casings and have holes punched throughout the case to help dissipate the heat. New batteries right off the line are very hungry for energy and will soak it up like a sponge for the first 15-20 charge cycles… the lead is not cured yet… I have seen new batteries right off the line take a charge for 8-12hrs… usually starting out with amperage up around 15-20 range (Wide Open) then as the charge cycle reaches higher voltages the amp gauge will start to go down. but still might stay in the 5-10 range for hours still. These chargers are designed to shut off automatically when charge is complete so let it run its course… I do suggest venting the area if charging in a garage or shed vs out side because off gasing does occur during the charge process of lead acid batteries and kinda stinks. Note – a fully charged 36v cart is usually around 42-43v… but during the charge process as the charger forces electricity into the batteries the voltage will be higher. Same applies to a 48v system where there you will see voltages well over 50 volts… Hope this is helpful in better understanding your golf cart battery charger and batteries. Power On… Pete

We get customers all the time that ask us the tough question. Should I repair my Ezgo Powerwise Charger or just replace it? This is something that Pete usually says… “If it is an electrical component and you are not an electrician or seasoned tinkerer just replace it.”   When it comes to spending time and money on something that you find yourself just standing there afterword with your fingers crossed hoping it will work – it is best to just replace the charger. Now this comes with a few other caveats because when customers call over the phone and try to explain the problem it has numerous possible causes being the charger needs to rely on the golf carts charging system to be operational as well in order to turn on. Several factors on the golf cart itself can cause the charger not to work or kick on. So if you want to take a stab at fixing or at least diagnosing the problem read on…. The biggest one is a completely dead cart. If the batteries in your golf cart are so dead the cart will not run and drive as intended you will need to charge each battery individually with like an automotive charger with clamps to revive before your Ezgo Powerwise charger will kick on if it is operational. Now you can also have a bad connection, a blown fuse or a wire in the charge circuit that is not completing the circuit. The easiest way to determine these few things is to get a voltage meter and check a few basic connections and the overall voltage of the golf carts battery bank. When you have six new 6 volt batteries combined in a circuit you will have approx. 38-39 volts. If the cart is not running and driving the voltage is most likely well below 30 volts and possibly why the charger will not turn on. With your handy volt meter you can check this and tick off the box. Yes or No? Next step would be to determine if the charge circuit is still complete? Take the positive and negative pins from the volt meter and insert in the cart side powerwise charge receptacle. You should have the exact same voltage you have at the positive and negative most terminals on the battery bank. Example – If the cart has 37.8 volts at the batteries, then you should have 37.7 – 37.8 volts at the charger receptacle. Yes or No?  If yes then the charge circuit is complete and the problem could very well be your Ezgo PowerWise Charger. Now if you don’t get the same voltage you will need to back track the circuit from the charger receptacle to the batteries. Double check all the wires going back to the batteries… work your way backwards with the volt meter until you can narrow down the fault. Golf Carts are fairly easy to work on so it should be obvious enough once you can narrow it down a bit and start looking around and chasing wires. Could be as simple as an in-line fuse. Now if all checks out:
  • Running and driving golf cart
  • Advertised operating voltage. (In this case 36v or greater)
  • 36 volts +  at the battery terminals
  • 36 volts + at the charger receptacle
EZGO POWERWISE CHARGER REPAIR OR REPLACEMENT Time to check the charger further. If possible see if someone has another 36 volt Ezgo golf cart  in your neighborhood with the same TxT 2 pin connector. Plug in to see if your Ezgo Powerwise charger works on their golf cart. If not then you can just get out the tools and start taking it apart or plan to replace it. Usually with these older style transformer based golf cart battery chargers we find they are corroded due to extended periods of time left out in the elements. Some other issues occur when a lighting strike takes place and it can cause a Power Surge that will burn something up quite fast. Usually a fuse will pop first if you have a fusable link in the charger circuit but most chargers do not as is the case with your Ezgo powerwise charger. Pete recommends using a power strip with a breaker built in to plug your charger into to avoid this common issue in South Florida. The power  surge will just pop the breaker on the power strip but save you about $500 – $1000 dollars depending on what kind of cart you own. So next in line is the most common internal part to fail over time is the Ezgo Powerwise Charger Circuit Control Board OEM Part#28667G01 If all other possible issues have been checked and are ok this is usually the problem. It is a fairly simple thing to replace with basic tools like pliers and screw drivers. Should you purchase one and want to learn how to install one here is a how to article that covers the installation Though there are a few other internal components that can cause malfunction or charger not to work. Things like the transformer itself – or relays. Sometimes it is a relay which is easily checked but transformers rarely go out unless the charger got really wet and just shorted out or got corroded over time. Repairing anything is a process your golf cart battery charger is no different. Usually this is where I ask myself should I bother to try to fix it or just buy a new one? If I use it often and need reliability I would just buy a new Ezgo Powerwise Charger so I don’t  get stuck or worry about if my charger is charging my batteries over night so I can play a round in the morning or not. Or burning up my batteries because it just doesn’t ever seem to shut off. I got plenty of other things in life to worry about. If I can just buy new from guys like Pete I will.

Things To Know Before Buying A New Golf Cart Battery Charger

We get phone calls and messages all the time from prospective customers wanting to know what is the best golf cart battery charger and how can they determine which one will work in their golf cart. So Pete asked me to write this short but informative guide and why I have titled it – Things To Know Before Buying A New Golf Cart Battery Charger. Things To Know Before Buying A New Golf Cart Battery Charger Basically the key features of a golf cart charger are they need to re-charge the batteries in your golf cart. So in order to be able to plug in a charger to do so it will need to be of the same operating voltage and the connector style must be the same. Depending on what brand of golf cart you own will  determine the style connector you will need.  For example – An Ezgo Golf Cart uses either a Crowsfoot connector on its older 36 volt carts, or the D36(TxT Style) connector which is rectangular shaped on the end, rounded on one short side with two pins inside two square holes. Newer 48v Ezgo carts use the triangular shaped 3 pin RXV connector. Yamaha golf carts use either a two pin Nabson style connector which looks kinda like a toy pair of binoculars , the Newer Style Yamaha carts have a three pin connector with people can say it looks like a triangle shape, or three leaf clover because the corners are formed by a radius. Then we come to the all and ever popular Club Car. Club Car Golf Carts older than 2000 can be 36v or 48v systems and will have either a crowsfoot connector or a round three pin connector. All club cars newer than 2000 usually have the round one. Though two different types of chargers use the round three pin connector. You will need to determine the year and model of your club car golf cart. You can look at the vin# on the cart. Usually found above the pedal assembly below the dash on a white sticker with a bar code or on the passenger side floor post facing the drivers seat. The first 5 or 6 letter/numbers will determine the year. Example A9905 = a 1999 Club Car DS manufactured in the 5th week of production that year.  Club Car golf carts newer than 1995 have what is known as an OBC “Onboard Computer” and if this is still functional in your golf carts charging circuit you will require one style charger that uses the three pin connector and if you club car is older than 1995 or if someone bypassed the OBC you will need a different one.
