Hi

My controller side hall sensor connections (yellow green blue) are only giving out 3.31v instead of 5 v. The red live is 5v as it should be.
My display is flashing E4 error which in this case means motor error. I think the controller thinks the halls are bad because they aren't switching due to not getting 5v current. Motor phase and halls check out ok on motor side. Fets are good, no issues with test.

Does anyone know what can cause the hall sensor connection voltage to be incorrect?

I'm kinda new at this.

The controller doesn't have halls so I assume the controller side you talk of is with the motor cable/halls connected ?
