1. Check for a blown fuse or a tripped breaker:
TSC-300 - On the power supply PCB: Make sure that the fuses at F1 and F3 are not blown. If there are blown fuses, check for shorts in the motor or motor cable in Step 2 before you replace the fuses.
TSC-1K - On the motor drive PCB: Make sure the circuit breaker  on the motor drive PCB is in the ON position. Verify 15 Amp Circuit breaker is installed for TSC-1K
If the circuit breaker has tripped, turn it back on. Test the TSC system. If the circuit breaker trips again, check for a short circuit in the TSC pump.
Note: On pumps made before December, 2016, you must use water-based coolants with The TSC-1K system. Thicker fluids like cutting oil will overload the pump and trip the breaker.
