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