Continuous power to the S terminal will overheat the coil. For Komatsu PC200-6 continues cranking after engine starts, replace the ignition switch immediately to prevent damage to this 600-815-8941 starter relay.
- π Voltage Confirmation First - This starter relay operates on 24V DC only. Before ordering the 600-815-8940 relay for Komatsu PC200-7, verify your excavator uses a 24V electrical system. Installing this 24V motor starter relay on a 12V machine will not engage the starter. Check your old relay for voltage stamp or measure across battery terminals.
- π Wide Model Compatibility - This 600-815-8941 starter relay fits for Komatsu PC200-6, PC200-7, PC200-8, PC200LC-6, PC200LC-7, PC200LC-8 series. Also compatible with PC120-6, PC210-7, PC210LC-7, PC220-6, PC220-7, PC220-8, PC220LC-6, PC220LC-7, PC220LC-8, PC230LC-6, PC230LC-7, PC138US-8, PC228US-1, PC228US-2, and PC228US-8 excavators.
- π Direct Replacement Fit - This 24V starter relay switch replaces melted or non-clicking original units. The 600-815-8940 relay uses identical mounting tab spacing and terminal layout (S, M, B, and ground posts). No harness modification needed. Disconnect the battery negative terminal before removing the failed motor starter relay for Komatsu PC200-6 or PC220-7.
- β‘ Symptoms of a Bad Relay - For Komatsu PC200-8 cranks slowly or makes a rapid clicking sound without starting, test this starter relay. A failed 600-815-8941 relay may also cause intermittent starting or complete silence when turning the key. Replace the 24V relay switch before the starter motor draws excessive current and damages the ignition switch on your PC210-7.
- π§° Installation Note - This motor starter relay uses 1/4-inch spade terminals. Clean corrosion from each wire terminal before attaching to the new 600-815-8940 relay. Tighten mounting bolts to 5-7 Nm only. After installing this 24V starter relay for Komatsu PC228US-8, test five start cycles before returning to work. Keep one spare relay in your service truck.
