The harness relays and circuit breakers assembly is the central electrical protection and switching unit within the pavement saw's wiring system. The relays act as electrically controlled switches, routing power to the appropriate circuits — such as the ignition, motor start, and control systems — while the circuit breakers provide automatic overcurrent protection, interrupting power if a fault or overload condition occurs. When this assembly fails or becomes damaged, the saw may experience intermittent starting issues, loss of electrical function, or unprotected circuits that are vulnerable to wiring damage, making prompt replacement essential for safe and dependable operation.
