Test the individual battery cells under load. Check for high-resistance corroded terminal connections or undersized battery cables causing a voltage drop. 7. Preventive Maintenance Schedule
Measure the voltage between the and B- terminals. It must match the controller's nominal rating. If it is too low, the controller will trigger an under-voltage lockout. Step 2: Check Key Switch Input (KSI) curtis 3501 manual
Connects to your accelerator assembly. Ensure your throttle type matches the controller configuration (e.g., 2-wire vs. 3-wire).
Typically ranges from 12V to 48V DC (check your specific model suffix). Display Type: High-contrast LCD or 7-segment LED. Operating Temperature: -40°C to +85°C. Which would you like next

Examine control harnesses for signs of fraying, pinch points, or exposure to moving parts within the vehicle chassis. If you need more specific assistance, please let me know:
: Check if terminals are properly connected and that the voltage matches the battery's nominal rating.
The is a microprocessor-based instrument panel designed for vehicle function monitoring and control. It is fully CANopen compatible and features an auto-ranging operating voltage of 12V to 80V DC . Technical Specifications
The 3501 comes in variants (e.g., 3501-4401 vs. 3501-2201). The manual is the only place that lists the settings. If you install a 48V battery into a controller programmed for 36V without consulting the manual, you will release the magic smoke within minutes.
