Can anyone give me an ideal what a circuit board for CM1 will cost me. Pump on starboard pole quit working. Light on top has been very dim on that pump since I bought the boat and has never "chimed" when powering up. Well today, it just quit working. When checking it out once home, the light was blinking red. Now no light. Did all the typical test, unhooked ribbon, tried remote app, checked voltage. Swapped circuit boards and pump works just fine. So Im guessing the board is bad.
