How do I know what AMP my alternator is?

How do I know what AMP my alternator is?

Look for a diagram under or near your fuse box cover. It will have individual amperage numbers (sometimes along with volts) already set by the manufacturer. Add up those numbers to find what amperage your alternator needs to feed the car’s electrical system. Verify this number with the part manufacturer, if necessary.

How many watts can a 100 amp alternator support?

If the load exceeds 40 amps the voltage will drop below the 13.5 volt level. The 100 amp rating refers to operation at 6000 RPM of the alternator shaft and this is the full rating of the alternator, 100 amps at 13.5 volts (1,350 watts).

How do I increase alternator output at idle?

The best way by far to obtain more power at lower engine speeds is to install an oversize alternator. The physically larger alternators produce more power at lower engine speeds and are much more reliable at higher outputs.

How many amps is a 1000 watt alternator?

How many amps is a 1000 watt alternator? If you have a mono block and a 4-channel amplifier that each are rated at and outputting 500-watts RMS power, you have a total of 1000-watts. Your alternator is rated at 14.4 volts, so the resulting calculation for current (amps) would be I = 1000/14.4. The result is 69.44 amps.
