Fuzzy photo but looks like the overloaded track goes to the top left terminal point?

Re: hoover board w/m

Thank you Martin..It does indeed go to left top term but this term is unused.This tracking is the neutral supply to board.Redid tracking and after running megger over motor and heater and checking pump. Switched back on pump ran continuously and blew tracking again when i went to switch off. Checked valves and swopped i/lock also.Would be gratefull if anyone could let me have wiring diag for this one.Paul

Had two of these recently caused by a short cct bridge rectifier in board in the base
on one repaired track and replaced rectifier board fixed it
But the second needed both boards replacing
Good luck
