Bilge pump

Will, Before I would mess with the wiring I would make sure it is not the pump itself. Not sure which one you have but if you can swap the bilge pump out with one of the livewell pumps you will be able to determine that the pump is good. Mine just unlatch and twist out. There are 2 pumps in mine. The manual one goes on when the button is pushed once. When pushed again it goes into auto mode. My second pump (auto mode) is controlled by a float that when the water rises it turns the pump on and then drops when the water goes down and turns pump off. When in the auto mode even if you turn off the main electric switch your second bilge pump will still operate if the bildge takes on water.You can also do a search and there is a lot of information there.I have a 2006 and have had to replace at least one pump motor and the float mechanism.Hope this helpsJohn

Clean the ground on the battery and each one of the grounds on the junction strip. I know they look clean and are hard to get to, but take them loose, use a wire brush, clean them and retighten. Then if it still doesnt work, check the pump as mentioned above.JohnThis is a good recommendation. I would also add that you should remove the positive wire from your cranking battery to reduce the possibility of accidentally shorting and causing sparks and other calamities. That way you can also clean the positive terminals and check your “jumper” for a tight connection too. Everyone should believe in something. I believe Ill just go fishing!

If you have a multimeter, you can check for voltage coming to the bilge pump wiring without having to disconnect other pumps.

I had the same issue 5 months after installing my a10. with the old digital BP-101 it would give and error and it was a bad pump. with the new a10 it doesnt say and i actually had both bilge pumps go bad, when i removed both bilge pumps on the impeller was black debris (oil+mud =sludge), had replacements from BCB with connectors and after hitting the bilge area with a mild de-greaser it was a 10 minute job to swap out both bilge pumps!
