Sierra Regulator/Rectifier for Johnson Evinrude Outboards, 35-Amp, Part 18-99405

The Sierra 18-99405 is a 35-amp regulator/rectifier built for Johnson Evinrude outboard motors. This component converts the AC output from the outboard's stator into regulated DC current for battery charging, while also protecting the electrical system from voltage spikes that can damage the battery or onboard electronics. As a charging-system component, it is a direct functional replacement for the regulator/rectifier used on applicable Johnson Evinrude outboards, matching the 35-amp charging capacity required for reliable battery charging on the water.

Frequently Asked Questions

What is the Sierra 18-99405 regulator/rectifier used for? It converts AC current from a Johnson Evinrude outboard's stator into regulated DC current for charging the battery, and it protects the electrical system from voltage spikes.

How many amps does the 18-99405 regulator/rectifier handle? The Sierra 18-99405 is rated for 35 amps of charging output.

Which outboards is the Sierra 18-99405 designed for? It is designed for Johnson Evinrude outboard motors as a regulator/rectifier component.

How much does the Sierra 18-99405 weigh? This regulator/rectifier weighs 0.9 pounds.

What is the UPC for the Sierra 18-99405? The UPC listed for the Sierra 18-99405 regulator/rectifier is 808282394363.

Is a regulator/rectifier the same as a voltage regulator? A combined regulator/rectifier, like the Sierra 18-99405, performs two functions in one unit: it rectifies AC to DC and regulates the output voltage, rather than only regulating voltage.

What happens if a regulator/rectifier fails on an outboard? A failed regulator/rectifier can result in a battery that will not charge or, in some failure modes, overcharging that damages the battery and connected electronics; the Sierra 18-99405 is intended to restore proper charging function.

Is the Sierra 18-99405 a Sierra-brand part? Yes, part number 18-99405 is manufactured and sold under the Sierra brand.

Does the 18-99405 include mounting hardware? The available product data does not specify included mounting hardware for the Sierra 18-99405.

What category does the Sierra 18-99405 fall under? The Sierra 18-99405 is categorized as an Evinrude outboard rectifier regulator.
