A3 Checking Voltages to Devices
Device voltages are often measured at the circuit board to determine whether the board or device is bad. If the
circuit board delivers voltage when device operation is called, the circuit board is probably good and the prob-
lem 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 within ±10% of the listed value. Refer to appendix
pages 50-53 for your specic circuit boards test point locations.
