How many amps should my alternator be for a 2000W amp?
How many amps should my alternator be for a 2000W amp?
A 2000W audio system at charging voltage is drawing about 142 amps. The stock alternator outputs 160A, so my system would be using up 88% of my alternator’s power, which would be fine if there wasn’t a car needing to be powered.
What happens if you replace alternator with higher amperage?
very interesting topic. Guys, I’ve been told that there are very high risk if we replace oem alternator to higher amp such 70 amp to 90 amp. The current will overloaded and can burn the engine’s wiring and other electrical parts.
What should I do if I have no alternator?
With no alternator at all (ie the engine is off) then you just flatten the battery. If the engine is running then you are adding charge but not as fast as you are emptying it. The big current is running down the winch wire. Not down the alternator wire. OK so I have a bigger alternator, I’d figure the current charging system can cope with that.
What’s the best way to calculate the size of an alternator?
Although it is possible to calculate roughly the right size based on the maximum amperage you’ll be dealing with, a good rule of thumb is to just go with the thickest gauge that will work in the application.
What should be the output of a 300A alternator?
So if all of the electronics in your car, put together, only draw 60A, then your beastly 300A alternator will only produce 60A. The way that current works is that any given electrical component will only draw as much amperage as it needs to operate.
How is the amperage of an alternator determined?
The alternator generates enough amperage to meet the needs of the combined electrical system at any given time, and then each component draws its share. In order to determine how much amperage a component is going to draw, you can divide its wattage by the voltage of the system.

How are alternator output ratings and the real world related?
Alternator Output Ratings and the Real World. The term “alternator output” refers to two distinct, yet related, concepts. The first is the alternator output rating, which is the amount of current that a unit is capable of producing at a specific rotational speed.
How can I tell if my alternator is working properly?
The more you turn on the more amperes are needed to power them so your alternator adjusts the output, if it’s operating correctly. Measure the alternator amperes output using your multimeter as before. The reading is near the maximum amperes you made a note of earlier.
