I have a j-340 240 volt tub.
The circulation pump is running, the heater light is on but the heater will not work. So far here is what I have.
The heater input at the board measure 230 volts ( across both terminals)
The heater output measures 30 volts ( across both terminals).
Unplug the heater output terminals and measured at the circuit board spades 30 volts.
The heater element reads 0.50 ohms on a 20k setting on meter.
Circuit board terminal for the heater output has a small amount of black smoke on then connection..
Looking for some advice ...
Thank you ..

You should be getting 220V on the heater output across both leads when the heater indicator light it on. Also, the heater element when test ohms should be around 9-12 on a 5.5kW element.
