It runs !  (my 1983 Ezgo conversion to solid state)
Thanks to you! I really appreciate all of your help. You have the best customer service in the world! 
I'm really excited about driving the old cart again! 
                                                                           Thanks,  Kory

These simple conversion kits

will bring your old in-efficient  drive system

into the 21st century, 

Once updated your cart can utilize speed and torque upgrades

available for modern carts

Why Convert from resistor coil to solid state speed control ? 

Bring Your tired old Ezgo into the 21st Century
Eliminate power robbing resistor coils
Discard the toaster oven parts ~ lol
Install a Solid State Speed Control System in just 3-4 hours.
 
Your pre 1991 Electric golf cart has the operating system as a 1950 golf cart.

Amperage wasting Resistor coils generate excessive heat and rob run time.


Early carts ( pre 1991) use a series of  graduated sizes of speed resistor coils to regulate speed. Each coil in the group offered less resistance than the previous one. When you stepped on the gas 100% of the available battery power (amperage) was drawn and speed was regulated by how much of this amperage was burned off (wasted) by the resistor coils. So even if you push the peddle a little it drains the batteries same as wide open throttle. The gas peddle operated a wiper which swept a contact across stationary lugs which connected to the resistors. Each resistor has a graduated resistance value which regulates how much amperage is allowed to flow to the motor ...the motor goes faster the more amperage it is allowed to draw.This wiper contact and board assembly was subject to meltdowns from high amp arcing which resulted in every problem from no go to welded in wide open throttle position. What a nightmare! 



Modern carts use solid state speed control. These controllers only draw as many amps as you ask for with the peddle.... If you push the peddle down 10% they deliver 10% of their capacity. I say their capacity because a controller is like a gate valve (or a hose bib) to the amperage stored in the batteries... We have different size controllers(valves) available so 10% of a 400 amp is less than 10% of a 650 amp controller.

 Increased Amperage = Increased Torque

 Increased Voltage =  Increased Speed

The solid state controller does not waste any amps and this will increases the run time.


I hope this helps you understand how your cart works and why a conversion to modern electronics is so important to your everyday enjoyment of the golf cart life.

Enjoy the Ride

Scottyb,
Thank You for your help. The conversion is done everything is working excellent. It was an easy install with your help, the instruction and diagrams were perfect. Thank you for taking the time to compile complete instruction, diagrams, and for responding to my emails to get me the best kit fir my needs. I Charged the batteries last night (38.3 Volt this morning) went for a little run this morning 19 MPH. I will tell everyone you are the go to guy.
