EZGO controller replacement

Leebird79 · 11-01-2014, 10:23 AM

I am new to golf carts. My 1998 Freedom burned up the controller its a Curtis 25864G05. Looking to replace it and solenoid with mild replacement, but not sure what to get. I have a AU2500 hi speed motor. Need some suggestions on plug in and play. May lift and tires later on. Thanks in advance for your input.

90% of the guys are using pkg #485 from our website. It includes the Alltrax SPM 500a 36-48v control and the 400a superduty solenoid with main fuse, resistor, and diode

go here > http://www.cartsunlimited.net/Custom_Options.html
It's about half way down the page.

The other 10% are using Pkg #484

The part number you gave is for a 36V-275A series controller (feeds a series wound motor).

Changing the tire size, changes the final drive ratio. Tires taller than 18" increase stock speed, but reduce stock torque, so you need a higher amp controller to offset the torque loss.

If you stay 20" and below, you might not need to lift the cart and a 400A controller with a 200A solenoid may suffice.

Lifting a cart is for tire clearance (or cosmetics) and doesn't alter controller amp requirements.

A 400A controller will turn tires up to about 23". Tires 23" and taller need a 500A (or larger) controller and a 400A solenoid.

The high current cable in a 1998 cart are most likely 6Ga, so they need to be upgraded to at least 4Ga. (all 13 of them)
Also, the F/R switch may need to be upgraded the handle the higher amps.

Leebird.....I gotta tell you.....the package that Scotty suggested WILL do you right. especially if you intend to lift and larger tires, as I bought a cart that was already lifted and had 23" tires, but a totally stock drive system......I installed the Pkg#485 and a set of his #2 ga. cables and absolutely love it!!

Thanks for the input. I'll look into it. Hopefully Santa will come early.
