How many amps does a Marine alternator put out?
How many amps does a Marine alternator put out?
This model has a dual foot mount and a dual pulley for ½” belts and an external fan. 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.
What is the difference between a marine alternator and a car alternator?
Automotive alternators rely on simplified voltage regulators, internally or externally, whose main task is keeping the starter battery topped off. Most marine alternators rely on external regulators to supply such features, although internally regulated alternators are available.
How many volts is a marine alternator?
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. If you have a voltmeter, with the motor running, put the leads across the battery terminals and rev the engine to 2000 rpm and check the voltage.
How does a Marine alternator work?
The alternator generates electricity by rotating a magnetic field in the rotor around a circle of stationary copper windings called the stator. One amp of field current will produce 30 amps of output current on the stator. Alternator belts are critical to the proper operation of the alternator.
How do I know what amp to get for my alternator?
The amperage rating on an alternator is basically just the amount of current that the unit is capable of putting out, not the amount it always puts out. So if all of the electronics in your car, put together, only draw 60A, then your beastly 300A alternator will only produce 60A.
Can you put an alternator on a boat?
Yes. Almost all outboards that have electric start and that were built in the last 20 years, will have either an alternator or a stater that charges the battery when the engine is running.
Can I use a car alternator on my boat?
No, it will be fine. The original alternator is nothing special. Its actually just a standard automotive alt anyway. For a boat that returns frequently to shore power, it will be fine, as the other one has been.
How many watts can a stock alternator handle?
So theoretically, since watts = amps X volts, the stock electrical system should be able to handle a 1512 watt load. Since 13.5 volts is a more realistic number for the alternator to produce, that would still mean the electrical system could handle a 1417.5 watt load..

Where do I charge my marine alternator battery?
We recommend directing the bulk of your charging capabilities to your house bank then charging any other batteries from the house bank. If the other batteries require the same charging V, they can be charged through a Voltage Sensing Relay (VSR).
