Curtis 1515 Controller Manual Portable Review
, which prevents the vehicle from jumping forward if the accelerator is pressed when the key is turned on. Diagnostic History
Features a built-in flash memory block. This allows technicians to plug in a handset and flash or download entirely new operational software without removing the physical unit. 🚨 Fail-Safes and Driver Profiles curtis 1515 controller manual
This is the starting point for any new installation. Pay close attention to the "Control Wiring" diagram. The 1515 usually requires a specific sequence of operations: , which prevents the vehicle from jumping forward

Approximately 230 mm (L) x 170 mm (W) x 80 mm (D). Weight: ~1.29 kg (2.84 lbs). Wiring and Terminal Guide
provides specific pinout tests to verify normal operation using a Volt-Ohm Meter (VOM): : Should read 0V with the pedal up and Pack Voltage with the pedal down. : Should read 0V with the key off and Pack Voltage with the key on. : Typically provides a reference for the MCOR (throttle). gfretwell.com Important Compatibility Note
Never apply power to a Curtis 1515 with the main leads disconnected. The flyback voltage will destroy the MOSFETs instantly. Read the safety section of the manual before you touch your probes to the B+ terminal.
