Difficulties when uploading a new charge profile (algorithm) can be attributed to outdated software on the IC charger.
Software update files can be downloaded below.
940-0001_DQT01-C041_rev5_66FB: IC650 models (includes ERIC/Club Car models)
942-0001_DQT01-C041_rev5_BF8: IC900 models
941-0001_DQT01-C041_rev5_BF15: IC1200 models
Open the .zip file and copy the "CHARGER" folder to a blank USB drive, then insert the drive into the USB port on the charger. Leave the USB drive inserted until the top, triangular LED turns solid green, as shown here:
The software will upload automatically and set the charger to algorithm #71. You can now upload other algorithms, which can be downloaded here:
