Hi everyone

I checked the battery but that seems ok holding steady under load. Not sure what else to check as the controller was tested on another truck also ok. The handbrake inputs are all correct.

Once issue i could do with clarification is if the handbrake switch should be positive when turning handbrake off it should go 0v or if it should be 0v and when turning handbrake off it should go 48v positive?

Running out of checks to do, I heard someone mention that this is a common fault on these Yale reach trucks?
