Visual Inspection: Overview

Visual inspection is an important part of diagnosis. The visual inspection should be done to locate obvious reason for the customer concern.

When performing visual inspection, check all items for abnormal conditions. Look for items such as bare, broken or disconnected wires and damaged vacuum hoses.
For the speed control to function properly, it is necessary that the speedometer cables, if so equipped, be properly routed and securely attached. All vacuum hoses must be securely attached and routed with no sharp bends or kinks. The servo (throttle actuator) and throttle linkage should operate freely and smoothly.

Any concerns found by the visual inspection should be corrected before further tests of the speed control system are made. The following items should be inspected.
