Mercury Outboard Voltage Regulator Problems

Mercury Outboard Voltage Regulator Problems And Solutions

As your outboard increases in use duration, some parts will sustain damages.

It can be a mercury outboard voltage regulator problems or any other problem.

When you see this, you have to make sure that you correct it early.

This will help prevent extensive damage to other parts of the outboard motor.

Some of mercury voltage regulator problems include low voltage output, excess voltage output, overheating or even a burnt regulator.

This guide will help enlighten you of these problems and how you can fix them.

Mercury Outboard Motor Voltage Regulator Problems And How To Fix Them

1)Battery Overcharging

When your outboard motor is running, you might want to run some electronic components in your boat.

This can be things like the fish finder or other components.

These devices make use of 12 volts or 14 volts.

With the help of the battery in the outboard motor, powering these devices are with no hassle.

This is because of the presence of components like the battery and voltage rectifier.

When the outboard is running, these devices run with the help of the charge supplied from the voltage regulator.

But if the outboard motor is not running, these devices run from the battery in the boat.

This will cause a battery drain if there is no charging system in the boat.

To avoid this, a charging system has to be present in the boat.

This is usually made possible with the help of a voltage regulator in the outboard motor.

But in charging the battery, this has to be done in a suitable voltage.

This is usually at a maximum of 14 volts.

This will help avoid an overcharging or undercharging issue.


1)Faulty Voltage Regulator

In an outboard motor, the rectifier helps to convert the alternating current supplied by the stator to a direct current.

This current is then rectified by the rectifier to a direct current.

After this, the converted DC voltage is used to feed the electrical components in the boat.

This can be in charging the battery in the boat or powering electronic components in the boat.

To achieve this flawlessly, the voltage regulator has to maintain a particular range of voltage which is usually 14 volts.

This will help charge the battery in the boat well without issues.

But if the voltage regulator is bad, then situations like release of higher voltage will occur.

This will lead to a battery overcharging scenario.


1)Replace Faulty Voltage Regulators

When you discover that your boat battery is overcharging, you have to check the charge producers.

In doing this, one of the components you have to really check is the voltage regulator.

This is because the voltage regulator holds the function of regulating the voltage produced by the outboard motor.

When the voltage regulator gets damaged, then the voltage released will not be regulated.

This will lead to an overcharging of the boat battery.

To solve this, you mave to make sure that you replace the bad voltage regulator to a good one.

2) Voltage Regulator Produce Less Voltage

When you have an excess voltage production in your outboard motor, it is a problem.

If the voltage produced is low, it is a problem too.

This will lead to the malfunctioning of the electronic components of the boat.

This will make the electronic components to malfunction due to low voltage.

The battery in the boat will deplete and not charge well too.


1)Bad Stator

Before a rectifier can convert the voltage to what the boat components need to function well with, a good voltage has to be produced.

This is where the stator comes in.

The stator with the help of the rotating magnets in the flywheel produced an alternating current.

This current is then converted to a direct current and used to power things in the boat.

But for this to occur, the stator has to function well.

If the stator is bad, then it will produce n insufficient voltage.

This will also affect the magnitude of volts that the voltage regulator sends out.

2)Bad Voltage Regulator

If a voltage regulator is bad, it will produce voltage less than what the boat electronic components needs.

3)Bad Flywheel

The magnets in the flywheel help the stator to produce an electric charge as it rotates.

If the magnets in the flywheel is bad, then the stator will not produce adequate voltage.

This can lead to a lower voltage production from the voltage regulator.


1)Fix Faulty Flywheel

When you discover a voltage issue in your outboard, you have to troubleshoot.

If you discover that the flywheel is the problem, then you have to make sure that you fix it.

2) Fix Faulty Stator

A faulty stator will affect the charge produced.

To correct this, you have to make sure that you fix the faulty stator.

3) Replace Faulty voltage Regulator

When you discover that the voltage regulator in your outboard motor is bad, you have to fix it.

In doing so, it is always advisable to get a new one from a trusted and certifier dealer.

This will help your outboard motor to produce an optimum voltage for running electronic components in the boat.
