Systems Components

Vehicles may or may not have the correct components for (and others) used smaller OEM style low current solenoids, some did not use Alltrax Controllers are compatible with these cars and other electric vehicles by using the proper configuration wire adapters or in most cases plugs directly into the existing wire harness.

Alltrax Controllers are HIGH power, HIGH performance electric motor controllers that require checking or replacing the main solenoid, heavy duty F&R switch, and adding the appropriate diode and resistor. This is true for ALL electric vehicles or conversions.

• SOLENOID – The main current solenoid (or called a contactor) that turns power on or off to the controller, the motor, and system using the Key Switch KSI.
• COIL SUPPRESSION DIODE – The Solenoid coil stores lots of magnetic energy, when turned off, a flyback voltage spike can occur. The diode absorbs this energy.
• PRE-CHARGE RESISTOR – provides a small trickle charge to the main filter capacitors in the motor controller. Having these “caps” charged prevents large surge currents when turning on the car.
• FUSES – These are two varieties: 1) The MAIN 200-600amp battery
• LOGIC 5 to 10amps fuse for control power.
