Important Troubleshooting Information
When troubleshooting a United Spas control system, no matter how minor
the issue is, the fi rst things that must be checked are the incoming power
to the control board and the output power of the transformer.
You will need to set your multi-meter or voltmeter for AC Volts when testing
voltages within the United Spas control system. You will only set your
multi-meter or voltmeter to DC Volts when testing the IC Regulator Chip.
Once you’ve completed the incoming voltage and transformer voltage
checks as outlined on the next few pages, you can proceed with further
diagnosis using the test points and instructions outlined later in this section.
Warning:
When working on the control box be aware that it may
contain high voltage wiring.
Warning:
Always keep your fi ngers and tools away from the circuit
board and any wiring while the power is on. Serious injury
may result!
Warning:
Make sure that the power to the control box is shut off
before touching any wiring.
