2000 ezgo txt series? Upgrades

[Brezzy01]

Also would you have or no where I can find the part numbers for it

[cgtech]

Getting the factory Ezgo 48v series controller new from Ezgo should not be your plan, it is probably a "over $1000 controller". Go with a Alltrax SPM or SR.

[Brezzy01]

No I'm not looking to get one from factory. Just need a part number to see if I can find a used one or one of eBay possible. Can't hurt to look.

[Brezzy01]

Would something like this work.http://m.ebay.com/itm/Curtis-36-48V-...%257Ciid%253A7

Here is some info I found.

CURTIS 1204M-5305 DC Motor Controller

New in box

36/48V, 325 Amperes

KEY FEATURES

Curtis Model: 1204M-5305

Norminal Battery Voltage (Volts): 36/48 (Two voltage settings are available. The voltage can be set to either 36 volts or 48 volts. By defaut, it is set as 48 volts, with an allowable working range 33-48V. If it is set as 36 volts, the allowable working range is 25-36V).

By defaut, we will deliver the controller of setting of 48V / 325A / 0-5kΩ (Throttle Type = "0").

2 Minute Current Rating (amps): 325
5 Second Boost Current (amps): 358
1 Hour Current Rating (amps): 140
Plug Braking (A2 Busbar): Yes

(Important information: 1204M-5305 is the upgraded version of 1204M-5301 controller, providing new functions "reverse signal output / main contactor coil driver" through the 6.35 mm push-on terminal J5. 1204M-5303 supports more throttle types. For more details, please read carefully the CURTIS 1204M/05M/09M/21M Manual.)

For the buyer without CONTROLLER APPLYING EXPERIENCE, please consult your cart/motor dealer and read carefully the CURTIS 1204M/05M/09M/21M Manual and CURTIS 1204M/05M/09M/21M Datasheet before making your purchase.

Wiring Diagram:
By default, the J5 terminal of 1204M-5305 controller is not activated. The controller wiring is same to the old 1204M controllers without J5 terminal.

If you want to activate the J5 terminal for using the Rev Input / Main Driver functions (please see the page 7 and 8 of 1204M / 1205M controller manual (PDF format)), please contact us for reprogramming the controller. There is not extra cost for reprogramming the controller.
OVERVIEW

Curtis 1204M programmable series motor controllers are designed to provide smooth, silent, cost-effective control of motor speed and torque. 1204M controllers are updated versions of the popular 1204 controllers, with the added functionality of being programmable—via the Curtis Model 1313-4401 Handhold Programmer or 1314 PC Programming Station. This means the controllers can be tailored to the needs of specific applications. In addition to configuration flexibility, use of the programmer offers diagnostic and test capability.
Curtis 1204M controllers are the ideal solution for a variety of electric vehicle applications, including industrial trucks, personnel carriers, material handing vehicles, golf cars, etc.
Features include:

High-frequency switching and ultra-low voltage drops provide high efficiency and silent operation.
Simple mounting and wiring with push-on connectors for control signals and plated solid copper buses for power connections.
Compatible with either a two-wire potentiometer or a voltage throttle.
Throttle fault protection circuitry disables controller if throttle wires become open.
High pedal disable feature prevents controller operation if key is turned on while throttle is applied.
Plug braking diode internal to controller.
Thermal protection and compensation circuit provides constant current limit over operating range and during under/over temperature cutback; no sudden loss of power under any thermal conditions.
Undervoltage cutback function protects against low battery voltage, including low voltage caused by external loads.
Easily programmable through the Curtis Model 1313-4401 Handhold Programmer or 1314 PC Programming Station.
Rugged anodized aluminum extruded housing meets IP65 environmental sealing standards for use in harsh environments.

If it supports ITS throttle type, it would work.

[kgsc]

cg it is listed as it will support it but it is not set to that by default. That was in the description. Brezz, you could probably make this one work but you might need access to a programmer to make changes.. More $$ and 325 amps really isn't enough IMO

[Brezzy01]

Ok so if I can't find any deals or higher amperage. Then what would you all recommend in decent price controller and solenoid to make my cart 48 v. Model numbers and I'm only driving around neighborhood. Not looking to be the fastest but 20 to 25 would be nice.

[yurtle]

Uh, try rereading post #2.

Navitas sells a TSX 2.0 Universal Controller, works at 36 or 48 volts, series or sepex. It comes with an adapter cable to convert it to each type cart. It comes in 420 and 600 amp versions.

I have several of these controllers and carts I am debating doing just what you are. My only concern is if the motor is strong enough.

If you want, PM me and I will point you to the Navitas documentation, I am not sure if I can post that here without it being advertising.
