Quoted from jimy_speedt:Hallo, this is a direct circuit between buttons and the coil. Check that your current flows thru the EOS (the blade switch), that the Eos is closed when the bat is idle.
If nothing moves at all, check of fuses first, on the aux power driver board and power board.
Then I suspect either a bad button switch contact that was making the weird effect, and that is now out of order, or a bad adjustment adjustment of the eos, or a bad eos switch.
Agree, sounds like an EOS problem. Check to make sure the contacts are clean and it is gapped and sitting closed and opening appropriately.
