G, day,
I am completely stumped, please help.
I was riding home, plenty of power left when the motor cut out. I unplugged and replugged, it ran for a while then cut out again never to turn again.
Your first thought would be battery, however it's an 11 cell lipo with a max resistance of 10m ohm per cell. Every cell charges to 4.19/4.20. the controller is programmed to cut out at 30V. I have also plugged the system into a 35v 10a power supply, it drew no current on acceleration.
Other things I have tried:
Made a 1200mah 12s lipo,
Tested controller MOSFETs,
Tested throttle at connection,
Tested throttle at the controller board,
Replaced the throttle,
Replaced the controller,
Tested the motor hall sensors at the controller board,
Tested motor windings with a meter,
Applied voltage to motor winding combinations to check it moves,
Disassembled motor to check for thermal sensors and damage to magnets.
I got nothing.
System is a mod mount cyclone style 3000w, no pas, no brake cutout, no key. When measuring from the board there is zero current draw when attempting to accelerate.
Any help greatly appreciated, I'm about to slap a 2 stroke on and be done with it.
