Read this before you buy. The conversion of old resistor coils to solid state is not Rocket Science but it is not a beginner's project either. It is in fact a level 3 or level 4 project. See the install ratings link in the main menu above. Be sure to understand the rating system before purchase.

We try to help you via email if help is needed. Understand we cannot guarranty you can do this and in some case profession hands on assistance may be the answer. If you are still with me - read on.

Pkg C54U 500 amps. Heavy Duty components for heay use like with bigger tires, more passengers, hilly campground or farm use. Any situation where the cart will do more than transport 2 people on flat ground... C54U is the better choice. This kit includes a built-in cooling fan which allows the control to sustain peak out longer. Controller has a 570 amp peak output. Use with the stock motor or any aftermarket motor. This kit will run on 36 or 48v right out of the box. It is ready for that 48v upgrade when you are.

C54U is the best fit for most older carts due to the size and weight of the older carts .

Now may be time to look into having the original motor refreshed or replaced.

This kit is a level 3 project. See install level rating system in main menu

Installation may require adaptation & bracket fabrication by the installer. New small gauge and high amperage cable will be supplied by installer. We urge installers to remove all of the original speed control system before starting and wire per our simple instructions & diagram for the best results.

All of the components in this kit are 36 volt and 48v compatible. Voltage selection below determines which solenoid precharge resistor is sent. Selections are 250Ω for 36v or 470Ω for 48v operation.

Choose operating voltage in the drop down menu then add to cart.

The discount prices below apply to customers who buy the universal conversion kit ONLY.

We apologize for the small price increase - import tariffs are hitting the golf cart industry hard.

Universal Solid State conversion for ANY cart

Heavy Duty DC182 kit ______________________________________ $219

Super Duty SW202 kit _____________________________________ $269

We offer tech support for the products we sell, not the carts you put them in.

For the best results remove all old wiring from the project cart and follow the simple wire instructions with the kit. The result is a simple dependable drive system.

Heavy Duty and Super Duty Reversing Contactors

are simply the best

directional switching device for any electric vehicle.

Pkg C42U 400 amps. Medium Duty components for moderate use like around the yard, park, or campground with 1-2 people onboard on flat or moderate terrain using stock size tires. Use with stock motor.

The standard golf cart go pedal sits at very upright position of 123 º

This new electronic peadal sits at a more relaxed 143 º.

Customers tell me 143º is more natural foot position.

All of the components in this kit are 36 volt and 48v compatible. Voltage selection below determines which solenoid precharge resistor is sent. Selections are 250Ω for 36v or 470Ω for 48v operation.

See F&R reversing contactor kits for your direction switching needs below

Each kit contains the proprogrammed Alltrax SR Controller, a matched heavy duty or super duty Solenoid, the electronic pedal assembly, general mounting hardware, the resistor and diode for the solenoid, and a main 250 or 400 amp fuse. Plus the install instruction and diagram.

Notes:

Due to the size and weight of most of these older carts C54U is the best bet for the job.

For bigger carts or added loads see the C64 kit.

2 gauge welding lead is the best high amperage cable for these carts.

Soldered or Crimped copper lugs connections are recommended.

Whichever method you choose must be secure and sealed from acidic vapor intrusion.

About 25 ft of cable is needed for the average cart.

Mount the components relatively close each other to minimize waste and loss.

The super 400a solenoid with both kits requires a 3/8ths lug (2)

The super-duty reversing contactor requires four 3/8ths lugs (4)

Everything else is 5/16ths lugs

Direction selection switching. Generally called the F&R .

There have been many size and shape F&Rs used over the years but, they are all 8 lug rotary switches with a rotating plate with 4 contacts that are dragging across 4 stationary contacts. You can use an older rotary switch like this with the C44U if the cart is running & the switch is in good condition. I suggest you do not - the switch probably has 30 years of wear on it. Use the SW182 for best results.

The C54U kit must use the SW202 for best results

The reversing contactors below are the best directional switching devices available for your project.

Use the heavy duty reversing contactor with C44U

Use the Super duty reversing contactor with C54U

Both reversing contactors come with the remote rocker switch and housing. The switch and housing can be mounted on any flat surface or the rocker switch can be cut into any panel or dash.

The reversing contactors come with a switch, a mounting bracket, hardware, & instruction

Reversing Contactors for travel direction switching

Here is a universal conversion for any old cart with resistor coil speed control

or multi-solenoid speed control or any combination of coils and solenoids.

I have been helping people modernize old carts for years. New technology allows me to adapt these principles to any electric vehicle.

This kit applies the same principles we have been using successfully with Ezgo and Club Car to any vehicle now.

This kit works on Cushman, Taylor Dunn, Melex, Turf Rider, Harley Davidson, Caroachie, Marketeer, Westinghouse, homemade mule-trains, and more.

The kit includes an electronic pedal assembly which replaces the original pedal.

This 5 wire pedal comes with a 2 foot harness and is wired directly into the system. A few simple crimp connections to the batteries, solenoid, and controller will have the high amperage current flowing to the motor at your command with precise control.

And to insure you get the performance you want the Alltrax speed control is completely user programmable with a simple usb connection. The program software is free and always up to date.

Of course - if all that technical stuff makes you cringe, I can preset the control so you don't have to.

This new generation speed control can easily switch between 2 user profiles. Like on road and off, or adult and kiddie driver with the flip of a (hidden) switch or on a speed limit dial for his and her limits.

Modernize your old cart today - This isn't your grandfathers Speed Controller.

The Biggest

Pkg C64U 600 amps. 680 amps peak 36 or 48 volt operation

This is our biggest controller ever offered in a conversion kit. Super Duty components for heavy use with bigger carts and heavier loads like with bigger tires, more passengers, hilly campground or farm use. Any situation where the cart will do all it can do... C64U is the best choice. This kit includes a built-in cooling fan which allows the control to sustain peak out longer. Controller has a 680 amp peak output. Use with a stock motor or any aftermarket motor. This kit will run on 36 or 48v right out of the box. It is ready for that 48v upgrade when you are.
