----infineon 40A controller
-----crystalyte hs3540R from grin with temp sensing
------CAv3
Ive ridden it over 300 miles without an issue until yesterday. Motor was getting hot at around 100 celsius, so I backed off.(ive ridden it TO about 120 degrees celsius a few times, but shut it down as soon as it reaches that temp) Then I had a nice downhill section so I gave it some throttle and the motor made a weird whining noise, the bike "shuddered" and i left off again. after about 30 seconds of coasting I tried the throttle again- under 100 degrees and it worked fine. After that I had a short uphill section and it made the whining/shuddering and the throttle cut out completely. I had to pedal it (75lb beach cruiser) about 3 miles to work. The battery voltage was reading fine....the CA showed proper throttle input and output....I bypassed the CA, wired the throttle directly to controller- nothing.
I swapped the throttle- both are good. I performed the mosfet test with a multimeter on my controller- none are shorted. The green phase wire connector(controller side) was melted slightly. The yellow phase wire connector(motor side) was melted pretty badly.... So is the motor junk....and is grin cyclery going to warranty something like this out?
I removed all the phase connector housings and tied the bare wires together and tried the throttle------the wires get very very hot quickly and the bike moves barely, in reverse and kind of shudders....
heres a pic of the connectors for the phase wiring
