My bilge pump is only working intermittently. When I hit the switch for it, the switch doesn’t light up. I have those orange translucent on/off switches. I drove the boat around for a while occasionally hitting the switch and after 10 min, it lit up and the bilge pump went on. I did’t dare turn it off until it finished pumping. Once it was done, I turned it off again. Then on. It lit up and then went out. Checked the fuses...they seem fine. Do the switches themselves go bad? If so, do you have a resource for ordering replacements? We are a couple months into boating season and this is a new problem.
