Comments about Sierra 18-5801 Solenoid:
The first two units I bought were defective and would not function. With the assistance of a West employee, we bench checked a third which checked out and has since performed well in my boat. The unit it replaced was the same part number and failed after one year. The design clearly needs improvement.
