Hi all. Need your advice with this weird case . Maybe you will have idea We had a Johnson marine electric 24V toilet. It was old and made problems, we called the shop and they said they have 50% sale so we bought it instead of buying parts and installed that with the same old switch . It worked for a second and then didn't work. I knocked on it and it worked for a bit. And then stoped working ...we were very disappointed, we troed and connected it directly to our 24V . Pump didn't work . We went back to the shop ....shop apologize and replaced, we took that home and again connected it to the switch and ....pump dosent work... connected to the 24 ...not working. Old pump is working ( bad , but workin). We are afraid that maybe something is wrong with our setting?
