EGO LM2000 mower started smoking after moving handle position. The handle relay, PCM, and + battery terminal were scorched. Continuity checks on wiring proved issue was PCM after bypassing handle relay and fixing + battery terminal wiring. PCM replacement was easy (label your wires before removing old one). My mower is surprisingly performing better and not overheating constantly. It now will turn on immediately after hitting a thick spot. Very happy to find the right part to make this repair a success
