The Controller combos below include the super duty 36 - 48 volt
MZJ400A dual stage solenoid. This solenoid requires two 3/8ths cable connections. Stock cable connections are smaller 5/16ths. Add 2 big 3/8ths cable connection lugs for the MZJ400A solenoid or 4 lugs for the SW202 reversing contactor.
350 amp peak replacement controls $395
BIG 3/8ths cable lugs
Electronic speed controls from Alltrax are made for the DIY person.
Some crimp on connectors may need to be changed for installation.
Most people with some mechanical ability can do this.

Fan kit is included on 500 and 600 amp SR controls
Upgrade the Forward & Reverse switch in all series drive carts when upgrading the speed control.
Remember if it doesn't have my HD switch cam in it, it's not really a heavy duty or ultra cooling F&R switch.
See our Reversing contactor conversion kits for the BEST in HD shifting and operation convenience.
We sell a complete line of Admiral motors to meet your needs.
Install cable upgrades for best results.
Generally 4 gauge is good up to 500a and 2 gauge is good for 500a and up systems.
Bigger cables provide less resistance & deliver more amperage.
More amperage = more torque. Happy Carting!

For all make Series carts. Ready to ship by 2-3 day delivery
The SR controls are the newest generation. They do things we wish our old controller did like reverse polarity protection on both input and output sides,
So you are protected from any mishap or install error
Many other features are new like built in cooling fan and automatic throttle signal calibration. Increased peak and sustained outputs make the 500 equal to the old 600 controls.... More program options like build your own throttle and torque curves. And simple USB compatible programming......
Built in cooling fan extends peak performance by reducing heat
and each controller carries a full 2 year warranty.
See 10 reasons why the new Alltrax controllers are the best ever!

What does the Speed Control do?
The Speed Control regulates the amperage flow
from the battery pack to the motor.
What is the solenoid?
The Solenoid is the on/off switch between speed controller
and the battery pack.
Bigger tires, more passengers, soft footing or hills
all require more power & increased amperage flow.
