Ants got into my fuse box at my pool and now most of the electric equipment does not work. I tested the connections to the individual components and they seem to have power. My question is: is there a way to test a circuit board to see if its fried or not with a volt meter?
It greatly depends on what the board is doing. Since I am going on assumption here this is the heater for your pool as well as the pumps and filter system? SO you should be able to check first for incoming power. You should have some form of thermostatic control firing the boiler or turning the electric heat on. those will be a smaller guage wire. And finally you should have something that turns on the pumps themselves. If you were to post a picture on here I would probably be able to tell you how to test it. Be careful and repost with a pic.Be here for an hour or so Good Luck
About the best that you can do is to test for power to the board. If you have the input voltage and aren't getting the output, then most likely the board is messed up or a fuse has blown. You may need to call in an electrician and have them look at it. good luck.
It would be hard to do, I feel. But, you can do a visual inspection of the components. If a capacitor or transistor etc. look burned you can test it with the meter set to Ohms but, you may have to unsolder to test. Be sure the power is off.
