Re: Bow Thruster problem
I say wiring. There should be a breaker and/or fuse between the two where connections could be corroded. Ground (or neg side in DC) is often the culprit, as they are often on bus bars or use other common grounds. Perhaps not on a dedicated battery. Still, as I said above, you should track down and clean every single connection. The corrosion is typically noticeable, but not always. I could be hidden below a ring connector, allowing voltage to pass when there is no load, but increased amperage caused the connection to microscopically separate.
