Missed the no load connected.
Sounds like the modules on off sensor. That determines if the ratchet relay is On or Off before pulsing the ratchet relay.
Is causing the ratchet to pulse a few times to try and determinant its on or off state.
If the ratchet relay did not go on when it should. It maybe jammed or contacts are pitted and not going On.
I have seen this mostly when turning On but was not sensed.
If it was jammed or ratchet broken. It probably chatters with both an on or off.
