0586075 Evinrude Johnson BRP Rectifier Regulator Assembly | Genuine OEM BRP Outboard Part

🔧 Product Description

Genuine BRP Evinrude Johnson 20-Amp Rectifier and Voltage Regulator - Part Number: 0586075

A genuine BRP combined rectifier and voltage-regulator assembly for selected 60-degree V4 Evinrude and Johnson two-stroke outboards.

The unit converts alternating current generated by the stator into direct current for the battery and electrical system, then regulates charging voltage to prevent battery overcharging.

⚙️ Key Features

• Genuine BRP Evinrude Johnson OEM regulator/rectifier
• Correct OEM part number 0586075
• Common unprefixed number 586075
• 20-amp OEM charging-system application
• Used on selected 90HP-115HP 60-degree V4 engines
• Combined AC rectification and DC voltage regulation
• Sierra, CDI, Mallory and Recmar replacements available

🚤 Compatibility

Commonly used on selected

• Evinrude 90HP 60-degree V4
• Johnson 90HP 60-degree V4
• Evinrude 100HP V4
• Johnson 100HP V4
• Evinrude 105HP V4
• Johnson 105HP V4

Important fitment note

• Confirm the engine model and electrical-system diagram.
• V4 and V6 engines can use physically similar but electrically different regulators.
• A failed stator or poor battery connection can damage a replacement regulator.

🔌 Function

The rectifier section converts stator AC output into DC. The regulator section limits system voltage to a safe charging level.

⚠️ Common Signs of Failure

• Battery does not charge
• Charging voltage is too high
• Battery boils or loses electrolyte
• Tachometer becomes intermittent
• Regulator housing overheats
• Connectors melt or discolour
• Battery voltage fluctuates
• Engine electrical accessories behave erratically
• Stator output is present but DC charging output is absent
• Regulator develops a burnt smell

🛠️ Service Notes

Recommended checks before installation

• Fully charge and load-test the battery
• Inspect battery cables and engine grounds
• Test stator resistance and output
• Check all regulator connectors for heat damage
• Repair loose or corroded terminals
• Mount the regulator firmly for correct heat transfer
• Do not reverse battery polarity
• Do not disconnect the battery while the engine is running
• Verify charging voltage at idle and elevated rpm
• Check tachometer operation after installation

Important cross-reference note

• Some aftermarket catalogues describe replacement units by a higher nominal current capacity.
• Confirm the plugs, wire colours, mounting design and stator application rather than relying only on the advertised amp rating.
• Do not confuse 0586075 with OEM 0586048, which is associated with a different 35-amp V6 charging system.
