Is there a difference in a marine alternator?

Spread the love

Marine alternators, for instance, have higher power demands than regular cars and trucks to run lights, radio transceivers, navigating equipment, AC/DC inverters, water makers, pumps, winches and other high-amperage devices.

What are Marine alternators?

High-quality marine magnet alternators are deployed in marine engines to convert mechanical energy into electrical energy and charge the batteries to drive the electrical systems.

Does BMW make boat engines?

Diesel engines To further compete with Volvo Penta, BMW added small diesel auxiliary sail boat engines, ranging from 7 to 50 horsepower, to the BMW Marine product lineup.

How do you size a Marine alternator?

Sizing The Alternator Alternators should be sized at 25% to 40% of the amp-hour rating of the house bank (unless you have major DC loads while the engine is running). Going with more alternator capacity than this is not recommended.

How do I know what size alternator to get?

The amp rating of the alternator is matched to the vehicle’s electrical system. Older vehicles with fewer accessories may only need a 70- or 80-amp alternator, while a newer vehicle with lots of electronics and accessories may need a 120- to 160-amp alternator.

Can a Marine alternator get wet?

Yes. Again, alternators are designed to handle water. If your alternator got wet and isn’t working, the problem is likely a wet diode or something similar. Give your car 24 hours to dry out using the tip above, and your alternator should be good to go.

Does an boat alternator have a fuse?

Alternators are self limiting devices and do not require any fusing at the alt end of the wire. The fuse goes at the battery end closest to the source..

Do inboard boats have alternators?

If you have an inboard or I/O (inboard/outboard) engine, then you too are likely to have an alternator to charge your boat batteries. While an alternator is a good way to charge your boat batteries while on the water, there is a lot more to know about maintaining your marine batteries.

Did BMW ever make boats?

Back in the late ’50s, there was an experiment conducted to see how the aluminum alloy OHV V8 of the BMW 507 roadster would perform as the powertrain of a speedboat. Not surprisingly, it was a success, but despite the positive results, the boat never progressed further than the experiment stage.

How many amps does a Marine alternator put out?

A typical small to medium marine diesel has a standard alternator with a rating of 55 amps; however this rating is obtained under the most favorable conditions. The typical sustained output from these stock alternators is 25 – 30 Amps.

Will a high output alternator damage a deep cycle battery?

That is, your alternator will only supply the amount of amperage a particular component demands—and no more. So high-output alternators will not harm your components or charging system, no matter how high you go with the amps.

What voltage should a marine alternator put out?

it should read 12.6 volts fully charged. that is 2.1 volts per cell. If it reads 10-11 volts then you have a dead cell; this is a very common problem with marine batteries.

What will a higher amp alternator do?

Better Battery Life That’s because an oversized alternator produces more output at lower speeds, including idle. That increased output prevents the battery from having to help supply the load—and this keeps it at a more ideal state of charge. The battery cycles less, which translates into better battery life.

How long do boat alternators last?

In general, you can expect alternators to last about 6-10 years, or about 80,000-150,000 miles.

How much does a boat alternator cost?

The Best in Auto Repair Labor costs are estimated between $278 and $351 while parts are priced between $322 and $345. This range does not include taxes and fees, and does not factor in your specific model year or unique location. Related repairs may also be needed.

Can I spray WD40 on my alternator?

You wouldn’t want to clean the alternator with WD40, as it would weaken the winding insulation. Hence, it can further cause some damages to the motor. Again, spraying WD40 directly to the alternator may ruin it, as the liquid may get to spots where it shouldn’t get to and cause harm.

What do you spray on an alternator?

Dilute any off the shelf degreaser to a 50/50 mixture with water before applying with a cloth or gently spray. Allow the cleaner to soak for 5 minutes before using a soft, short-bristled (2-3 inch) brush to clean heavily soiled areas and terminal connection points.

Can an alternator drain a battery?

A corroded or defective alternator diode will faultily continue charging the circuit even when the car off. This, in turn, will drain your car battery and cause the car not to start.

What happens when alternator fuse is blown?

If the alternator’s fuse or fusible link is blown, the alternator will not be able to charge the battery. The battery then doesn’t store enough power for starting the car or keeping it running.

Should you put a fuse between alternator and battery?

What size fuse do I need for alternator?

While the size of your fuse depends on the amperage of your alternator, you should generally select a fuse that can handle more amperage than your alternator is able to output. For example, if your alternator outputs 200 amps, you should choose a fuse that’s no less than 200 amps.

Does a marine battery charge when engine running?

Most modern outboard motors that have an electric start will have an alternator which will charge your starting battery once the motor is running.

Will my boat battery charge while running?

Once the outboard is running, its alternator will recharge the cranking battery to compensate for the power delivered while starting the motor, and for any power drawn for other “house” needs, including live well or bilge pumps, fish finders, or navigation lights.

Does a boat alternator charge the battery?

Let’s recall that in 99% of boat systems, the alternator is directly connected to the starter solenoid. Therefore, whatever battery is connected to the starter is also the battery that will get a charge from the alternator.

Does BMW make a yacht?

Ever heard of the Intermarine 55? It’s a $2.2 million motor yacht designed by BMW Group’s DesignworksUSA and executed by Intermarine, a Brazilian boat maker.
