Help! After turning off all pool equipment and checking the electrical current in the pool with a voltage meter our Polaris pool booster seems to be the culprit of the electrical current in the pool. From the outside of the booster pump all seems to be in tact and grounded. Polaris is operating normally when running. Any ideas on what could be causing this? Also we have had a few thunderstorms in our area since we last swam. Thank you!
