Review on ๐ŸŒŠ Rule 35A Rule-A-Matic Mercury-Free Bilge Pump Float Switch - White: Product Review & Buying Guide by Jack Watkins

Revainrating 3 out of 5

Good switch. Pretty easy to install.

Works great. Be careful not to mix up the wires. They are the same color. But there is only one way to connect. The manual doesn't say which cable is which. Test before installing. Connect a gray cable to the battery. Then use a voltmeter to make sure the 12V supply is getting through. If there is no 12V, then vice versa. Swap the gray wires. Test again. One gray wire goes to the battery, the other to the pump. For me, the brown wire on the pump is positive. The black wire on the pump is grounded.

Pros
  • Permanent test results
Cons
  • Hard to tell
