This section covers heat sinking—the 1520 can dissipate over 200W of heat. The manual provides:

However, a common complaint among technicians and fleet managers is the difficulty of finding a complete, easy-to-read . The official documentation is dense, often spanning over 150 pages, and is not always distributed freely online by Curtis due to liability and dealer restrictions.

A: Yes. With the 1311 programmer, go to Diagnostics > Restore Factory Settings . Without a programmer, you cannot. Some OEMs lock the controller, requiring their special code.

Dedicated pins for Forward, Reverse, Interlock, and Brake switches.

Controls how aggressively the motor slows the cart when you lift off the pedal. This can be disabled by setting the regen current limit to zero. Torque Assist: Sets the amount of motor assist when starting on hills. Troubleshooting & Maintenance

If you have read the manual and still have issues:

Ensure the mounting surface remains clear of debris to maintain optimal thermal dissipation.

Periodically check power connections for corrosion or looseness. Loose nuts cause high resistance and localized melting.
