Hi, I have an Aqua Logic Chlorine Control System (not sure of the model #) and it tripped the main 120V breaker the other day.
1. Verified the two fuses on the main board are ok (20A, and 3A).
2. I disconnected the two main 120V input wires to the main control board (black and white), turned on the breaker and it did not trip.
3.I plugged the wires back in and the breaker tripped again.
4. I measured the resistence across the 120VAC input terminals on the main board. It was ~35 Ohms.
5. I measured the resistence across RZ1. It was also ~35 Ohms.
6. Removed RZ1 from the board (de-soldered) and measured the resistence across the 120VAC terminals on the main board. Resistence was ~ 35 Ohms.
I don't know what the values should be in the above measurements, but 35 Ohms between 120VAC input terminals doesn't seem right.
Here is a link to a picture of the board (sorry, I don't know how to attach the image): http://www.amazon.com/Hayward-GLX-PCB-M ... B0030E95PO
Does anyone have any information or ideas?
Thank you.
