ES2 motor vibration (missing phase?)

Postby H1tm4n Thu Oct 01, 2020 7:23 pm

Hello everyone, after 1200 km my ES2 (with an external battery) broke down.

There is no voltage from the control board to the motor on the blue wire (only the yellow wire has voltage). No error codes, the engine works, but it is just sluggish (lots of vibration and noise) and it heats up fast if only one of the two phases is present. There are no obvious signs of damage to the board. Tested the MOSFETs. All 8 of them had no continuity from drain to source. Already ordered a 30 EUR replacement on eBay but just in case I would like to fix this one if possible.

Any help is much appreciated! 🙂
