No in line fuse. what is this intelletec relay and any clue where it might be? Something is clicking inside the wall at the front control panel (LPG, Fresh, black,grey, water, & battery)where there is also a switch with a green light for the water pump. It clicks when any of the 3 water pump switches are hit. The pump works and as a temporary fix I have wired from the bathroom light so when the light is on the red light comes on at that location as well as at the front panel and in the basement along with the water pump. Switch off the light and everything stops. With this fix when the light is on the pump works but the pressure switch will cut it off as soon as it reaches max pressure.
Still don't know what is wrong.
