Series, Sepex, or AC Drive System?

There are three major types of drive systems found on today's electric golf cars. It is the customer's reponsibility to properly identify their drive system before purchasing any upgrade parts. If you do not purchase the correct components, they will not work. This guide that we have compiled is designed to assist you in the identification process and point you in the right direction.

AC Drive System:

This one is easy. The E-Z-Go RXV is the only golf car in mass production today that utilizes an AC drive system. If you have an E-Z-Go RXV we can not help you with your upgrades. As with most other vendors, we do not currently carry any AC upgrade parts at this time. AC is still fairly new into the game and is a very expensive system. We hope to offer components in the future.  If you are not sure if your E-Z-Go is an RXV, locate the vehicle serial number and go to www.shopezgo.com to use their serial number lookup feature. This will tell you any information that you will need to know about your vehicle.

Series Drive System:

The workhorse of the group. Series cars are very simple systems. They use basic DC electricity to energize the electric motor and make it run. Controllers are available in all sorts of shapes and sizes to provide power to your motor.  Series vehicles have lever operated forward/reverse switches to reverse the polarity of the motor to allow them to run the other direction. See the photos and information below to help you identify your drive system.

SepEx (Regen) Drive System:

This is the most popular system in modern golf cars built today. The SepEx (Separately Excited) motors use two separate circuits to control the operation of the motor. Power is provided to the motor from the controller, but the controller is also able to control the field coils of the motor separately from the main power. This results in a motor that is capable of regenerative motor braking. Regenerative motor braking is a safety feature that is built into todays vehicles to keep speed under control in todays more powerful carts.

Club Car "Series" System

This one is easy. All Club Car series-drive systems are equipped with a rotary lever for forward and reverse operation. The electric motor will have four terminals, labeled A1, A2, S1, and S2. There will NOT be a speed sensor on the end of the motor and there will NOT be a Tow/Run switch under the seat.

E-Z-Go "Series" System

First you'll need to know which E-Z-Go you have. All Marathon cars are series. E-Z-Go Medalists were only built in 1995. They were all series cars as well. With the introduction of the TXT model in 1996, it gets slightly more confusing as there were more drive systems to choose from. The TXT series vehicle has a rotary F&R lever with a mechanical linkage that runs down to an F&R assembly that is bolted into the floor of the battery compartment (see photo below). The electric motor will have four terminals, labeled A1, A2, S1, and S2. There will NOT be a speed sensor on the end of the motor and there will NOT be a Tow/Run switch under the seat.

Club Car "Sepex" System

This is where it gets complicated. Club Car offered several of these systems. All of these systems use a rocker style F&R switch, and have a speed sensor on the end of the motor. All Club Car Precedents are Sepex

E-Z-Go "Sepex" System

E-Z-GO DCS System - found on early TXT vehicles. Had rotary F&R switch but did NOT have a mechanical linkage like the series cars.  There is a tow/run switch under the seat on the controller cover. There is NOT a speed sensor on the motor.

E-Z-GO PDS System - 36 volt system. Rocker style F&R switch located on the dash of the car next to the key switch. Tow/Run switch can be found under the seat. There is a speed sensor on the end of the motor.

E-Z-GO TXT 48 - Much like the PDS system, only it uses a black Curtis 48 volt controller and has six 8v batteries instead of six 6v batteries.  F&R switch is on the dash, tow switch on controller cover, and has a speed sensor on the motor.

F&R Lever for E-Z-GO DCS.  Save lever as a series car, but there is no mechanical linkage behind the switch. It has a small silver rotating disc instead of a linkage rod.
