Golf Cart Guru • I love hearing from you guys. It’s fun to hear about your interests, concerns, and problems. I’m glad to offer advice and help where I can. In this issue, I’m going to address another question. Here it is, “My electric golf cart lost its reverse can I fix it myself or do I have to take it to a service center? It’s a 1996 TXT” A big problem with diagnosing malfunctions is gleaning all pertinent information. By the way, I don’t mean this to sound like a critique of the question it’s just to be informative. Most of the info we need is here. Primarily what we need is make, model, year, and drive type for start. In the question, there are a few holes that we can figure out from the things we’ve been told but there is one we can’t. Here’s what we have and don’t have. Make, He doesn’t tell us the make but based on the model we know it’s an E-Z-Go. Model, TXT, Year, 1996. The important part we’re missing is drive type. He tells us it’s an “electric” which is helpful but in 1996 the E-Z-Go TXT electric was available with two different drive systems, Series and DCS. The Series system or what E-Z-Go calls “Non- DCS” is most easily identified by the mechanical Forward & Reverse lever next to the driver’s right calf. If you flip up the seat on the backside of that lever you’ll see a bell crank and linkage going towards the passenger’s side of the vehicle on a slightly downward slope. This linkage connects to a mechanical Forward & Reverse switch that has four large gauge or power circuit cables attached to stationary contacts and a rotor that creates a connection between those contacts. In addition, there are micro switches that are opened and closed depending on the position of the rotor. These make and break the connection in the small gauge wire logic circuit. Poking around in this area with thirty-six volts present can be dangerous. If you are comfortable with previous articles talking about discharging the controller and powering down the car then you can look for a loose connection, broken wire, misaligned microswitch, etc. If you’re not comfortable The Is your golf car making a funny sound? Do you have a repair question? Need to know how to install something? Ask the Golf Car Guru. DON’T DO IT!!! It can spoil your day or worse. The second electric drive system that E-Z-Go produced in the golf cart that year was the DCS. This is a separately-excited or shunt system. Sometimes referred to as “regen” This system also has a mechanical Forward & Reverse lever next to the driver’s right calf. The difference is under the seat on the back-side of the lever there is an aluminum disc that activates and deactivates two micro switches as it’s moved from forward to neutral and reverse. As with all microswitches, these are in the logic circuit. They send a signal to the controller and it controls the change of direction in the motor rotation. Another thing to look at is the four connections on the motor. Many times they become loose and overheat or break. The same thing applies, be cautious. Don’t poke around and cause a bigger problem or worse cause a short and injure yourself. IF YOU’RE NOT CONFIDENT IN WHAT YOU’RE DOING TAKE IT TO A PROFESSIONAL! Good luck, take care, be safe. • Have a question? Send it to Tim at: [email protected] JUNE 2018 19
