evening guys,
i have a mqcon Sabvoton 72150 from 2019 and its been running perfectly well but the phase wires and battery power cables inside were a bit chewed up so i decided to unsolder them and put in 8awg silicone cable instead with colour coordinating heat shrink to keep track of which phase is what colour. finished up and re-assembled everything but now the controller doesnt work right. when i pull the throttle even a little bit it jumps to full power of whatever gear its on then slows down slowly to a cruise type speed but doesn't stop. i thought it was a throttle error so i disconnected the throttle while it was spinning and nothing changed. i then disconnected every port except the throttle, jumped the display and ignition port so it would turn on, and again it wont stop turning. i tried using ebrake regen and it does a really nasty judder but it did stop it. i tried resetting it in mqconnect app but no change. i took it apart and observed the circuit board to see if anything was burnt or wires were in the wrong place and nothing again. is it possible heat damage or logic chip bricked? i touched no other wires during this process, all i did was unsolder phase wires and battery wires and replaced them.
