Hayward Aqua rite SWG Tcell-9 high Volts & Amps while generating

[Dalia19]

The numbers just don't make sense.

What is the voltage when not generating?

I would check the amperage and voltage separately with a meter at the red and black wires.

What is the input voltage (measured)?

Is the voltage selector set correctly?

Do not change the selector unless you are 100% sure that it is set incorrectly.

Can you show a picture of the circuit board with the display board removed so that we can see the whole circuit board?

Has the circuit board ever been replaced?

If yes, was it a genuine Hayward or was it a generic Chinese aftermarket circuit board?

Can you show a picture of the cell label?

You need to verify the actual salinity with a good test kit or calibrated salt meter.

Voltage is 38 when system is off.

The thermistor has been replaced, but it looks like it is developing a crack.

Check it well for cracks.

Check the input voltage.

It is set for 240 volts, so the input voltage should measure about 220 to 250 volts AC.

Check the DC voltage at the red and black wires.

What is the voltage reading from the board when not generating?

Check the amperage by using a clamp ammeter around both red or both black wires.

You need a clamp ammeter that can measure DC amperage.

Voltage is 38 when system is off.

That's really high and unusual.

That could explain the high current.

Maybe the board is reading the voltage incorrectly.

Check the voltage with your own good meter.

If the voltage is really that high, maybe the input power is really high or maybe the transformer has a problem.

Check The input voltage.

Check the transformer output AC voltage at the two yellow wires to see if it is in range.

Verify 20-24 VAC between yellow wires.

Check the back of the circuit board for any obvious damage.
