Electrical wiring question
I just added a second bilge pump (2000GPH Rule), it works fine. During that installation I discoverd the float switch for the primary bilge pump was no longer working (timing is everything ).
I purchased a new Rule 1100GPH pump with the fancy water sensing switch. This pump is replacing a Rule pump with float switch. The pump is wired through a Rule 3 position switch (Auto - OFF - Manual).
The newly installed pump isn't working correctly -- when I select Auto the pump runs constantly. OFF is off, manual is as it should be.
Did some trouble shooting but couldn't find a smoking gun. I then hooked the 1100GPH pump to the wiring for the 2000GPH pump...the 1100GPH pump now works correctly -- when on Auto it only comes on with high water or pushing the test sensor. I think it must be the wall switch so I buy a new Rule 3 position switch and install it --- exact same problem -- with switch in Auto the pump runs continuously.
I switched the brown/white and brown wires on the back of the wall switch....no change.
Since I was out of time this week for working on the boat I headed home and about an hour into my drive I thought about polarity. Is it possible I switched the wires on the battery? If I did would it cause the issue I'm having? It's possible I did switch them. When I found the original pump malfunction I traced the wiring back to the battery and found the wires simply "twisted" and jammed under a wingnut. I crimped on ring connectors and reconnected to the battery...now I'm not sure I put them back the way they came off.
The question is would reversing the wires at the battery cause the pump to run continuously with the switch in "Auto"?
Thanks in advance.
