there are two ? sensors ?cutout ?? adjacent to the motor in the hedge trimmer body.
This one, here stripped of its shrink wrap was placed close alongside the motor They are approx 6--7 mm diameter.
The coiled wire is continuous and has 3 turns around the "pin in the end of the iron slug
Is it supposed the cut off with excess current?
I ask because the trimmer stops working after around 30 seconds to a minute and the resumes after a :cooling period of a minute or so under light load. The motor also stops if the trimmer is held upside down resuming when turned upright again. There are no obvious loose connections and it they all show continuity when the trigger is switched on. .
