EZGO 36v to 48v Conversion

[OUTL4W]

A 48v conversion will add approximately 30% or more for sepex carts to both speed and torque on your existing 36v cart.This write up is for both the series and the sepex cart.
This is for controllers rated at 400 amps or less.

Larger controllers require a different solenoid, fuse and diode.
Larger controllers on series carts will also require an upgraded F/R switch.

What you will need:

1. Controller that is capable of 48v
2. 48v Solenoid
3. 470 ohm 10w resistor
4. 1 amp diode PN IN4004
5. Fuse 250 amp
6. Optional 4ga cable set (11 -13 cables)
7. 48v Batteries (8x6v, 6x8v or 4x12v)
8. 48v Charger

Basic Step by Step:

1. Take a photo of your existing wiring layout for reference.
2. Switch from run to tow if you have a switch.
3. Disconnect the batteries.
4. Change the controller (some controllers may have adapter harnesses).
5. Reconnect the batteries and confirm the controller works.
6. Disconnect the batteries.
7. Install the new solenoid.
8. Install the new resistor across the large posts on the solenoid.
9. Install the new diode across the small posts on the solenoid, stripe to positive side.
10. Install the new batteries (6x8v) and don't forget to re-install the charger wires. The wiring will be exactly as they came off the original batteries.
11. Install fuse between the negative on the battery pack and the controller.
12. Confirm that you have 48v at the charger receptacle.
13. Short test drive. I know you shouldn't do this but your curiosity will make you want to try it out.
14. Recharge batteries.

If you have a programmable controller it is pretty much plug and play. They generally come pre-programmed. If you are planing on tweaking the parameters it can be done later.
