Does anyone know where I would find the aerator timer chip on my boat? The schematic says its connected to the switch, but all I see under there is a plastic connector that seems to connect a lot of wires to the main group that goes back to the battery. My aerator pump runs constantly when the power is on to the control panel and the switch does nothing. The only way to turn it off is to turn the accessories power key off, which kills everything else on the dashboard.
