My Johnson WPS 3.6 water pump has always caused the "house" boat lights to flicker when it pulses. I did some rewiring and it got worse. I'm thinking of running a 10 gauge cable directly from the battery to the pump to power it exclusively. Any thoughts that could help with this? What about a capacitor on the pump that could smooth out the voltage fluctuations? Alternatively capacitors on the lighting circuits? I recently replaced the incandescent bulbs with LEDs, but (senior moment) I can't remember if the LEDs flicker more than the incandescents . Thanks for any help.
