While in the mechanical/pump room today I had a pump that started kicking off and on. I walked out to the bay and a gentleman stated it started acting up out of the blue. After he left I put money and used the time to wash out the bay. The first 3 minutes was fine, when I hit the 1 minute remaining it started turning off and on again. Then I realized it was in sync with the timer flashing. When the timer would flash off the pump would kick off, then come right back on when the display would light back up. The actual breaker in the Coleman Hannah Powerpack was engaging and disengaging in sync with the timer flashing. I am going trouble shoot it tomorrow and was wondering if any of you experienced this before?
