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.
• 2004 ProTech LED J-315, J-325 Models (US/Canada 60Hz)
Device Test Points Voltage ±10%
Pump (Low Speed) 18 and 19 120 VAC
Pump (High Speed) 18 and 20 120 VAC
Circulation Pump 16 and 17 120 VAC
Heater 6 and 7 120 VAC or 240 VAC*
Ozone Generator 14 and 15 120 VAC
* Depends whether hot tub is connected to 120 VAC or 240 VAC supply
