A2.0 Checking Voltages To Devices
Device voltages are often measured at the circuit board to determine whether the board or the device
is bad. If the circuit board delivers voltage when the device operation is called, the circuit board is prob-
ably good and the problem lies with the device or the wiring to the device. The following voltage chart
shows operating voltages for all major hot tub components. Voltage is considered good if it is within
±10% of the listed value. Refer to appendix pages 50-51 for your specifi c circuit boards test point loca-
tions.
