What are benefits of a high-amp alternator? Understanding the duty cycle is the key!

Duty cycle is a term which defines the number of minutes, within a 10 minute period, during which an alternator can safely produce a particular amount of charging current -- delivered into a restive load.

For example, a 130 amp truck alternator will typically have a 30% duty cycle. The alternator can charge continuously at 50 amps -- but if operating at full capacity of 130 amps, it should be "rested" for at least 7 minutes after 3 minutes of continuous high amp charging.

On the other hand, a 230 amp high amp full duty alternator will typically have a 100% duty cycle. This alternator can generate continuously at 230 amps into a restive load.

Alternators do not have internal protection systems that prevent this sort of over stress, leaving the monitoring to the owner or operator.

Look carefully at your alternator’s specifications. In fact, most auto parts store units will not give you much detail in specification and the warranty that comes with it. Most alternator manufacturers will identify their alternator by its maximum possible power generation capacity only, even though that alternator may only be able to produce that level of power for a very short period of time.

 Replaces 6G Alternators. On vehicles with 6.4L & 7.3L pre-2008

 Wiring harness and extended mounting bolts included.

 If this alternator is replacing a lower amperage unit it is recommended that the b+ and b- cables be verified as capable of carrying the additional amperage. An upgrade to the cables may be necessary. Failure to do so may result in less than maximum performance from the alternator and a potential for overheating of the cables.

Where space allows can be used to replace Ford 3G, 4G unit. 

The engineering way to ensure that you have the right size wiring and clean connections is to do a voltage drop test on each leg. This can be accomplished with a carbon pile and multimeter.

  1. Disconnect the battery
  2. Disconnect the alternator (or totally remove the old unit and do not install the new one yet)
    1. Make sure the B+ cable is not contacting the frame or a ground point.
  3. Re-connect the Battery.
  4. Connect the carbon pile
    1. Red clamp to the Battery+ lug/terminal on the alternator end of the cable.
    2. Black clamp to the alternator mounting bracket on the engine
  5. Connect your probes on the multi-meter, with it set to DC Voltage auto-ranging, or in 0.00 range (we want to see tenths of a volt)
    1. Red probe to the Battery+ lug/terminal on the alternator end of the cable
    2. If your cables are long enough: Black probe to the Battery Positive post on the battery.
  1.      If it is too far, connect to a the battery positive post on the power distribution post
    1. At this point the meter should read ZERO volts
  1. Apply a load to the circuit with the carbon pile, ideally 250 amps (factor of safety) for about 30 seconds to 1 minute
    1. Watch the multi-meter, if you have properly sized wiring and clean connections, it should read less than 0.30 Volts
  2. Next test: Ground path
    1. Red probe to the same ground point where black clamp is on the alternator mounting bracket on the engine
    2. Black probe to the Battery Negative post on the battery.
    3. At this point the meter should read ZERO volts
  3. Apply a load to the circuit with the carbon pile, ideally 250 amps (factor of safety) for about 30 seconds to 1 minute
    1. Watch the multi-meter, if you have properly sized wiring and clean connections, it should read less than 0.30 Volts

If the distances were too far for the multi-meter probes, you will have to repeat this test on each leg, until you have made your way all the way back to the battery.

 

Note: this only ensures that the alternator’s load path is adequately sized and has clean connections.
