Connections which are not watertight can allow moisture to travel through the individual strands of the wires and make it’s way into the scale, causing permanent damage to the electronics. Crimp each end of the wire into the connector with a wire crimp tool (tool not provided).
- Page 37 The steer axle weight can be estimated because the weight placed on a fixed position 5th wheel is in a consistent, predictable location on the frame. After calibration, the Right Weigh gauge calculates how many pounds of weight are typically placed on the steer axle, for every pound placed on the drive axle group.
