Question about Electrical Supplies

1 Answer

I have 54 series AG-TRONIC generator, about 25 yrs old used less than 100 hours. There is no output voltage, so I flashed the field with 120volts -should have been 12 volts DC. This did not solve the problem, probably needs some repair now. What should I look for now ? Is there any ohm readings I can take?

SOURCE: low voltage generator output

Hi there,
Nothing about the bumpy dirt road would have done this but the 10 years of storage might mean that you've got dirty slip rings. Plugging a drill into the 10Kw generator isn't going to tell one much about the power coming out of it, you need a stove :-)
After a camshaft replacement I'd want to use the "Hz" function of the DVM to make sure I was getting 60 Hz.

Regards,
Carl

I found out that the gasoline motor was turning too fast so I had to turn down the speed of the motor with the adjustment screw.

SOURCE: Generac 5250 with a 8 hp Honda engine. Runs fine, no output

Take a resistance reading across the brushes with and Ohm meter. (not running) You should read a low resistance. If you have no resistance across the brushes then then either the brushes are not mating with the armature or the the armature is open.
IF you have resistance then the AVR (Automatic Voltage Regulator) in the endcap has failed. With the engine running and the Brush block disconnected you should have 4 - 12 VDC on the two wires going to the brush block. No voltage = bad AVR.

Thanks for choosing FixYa.

Follow these steps to flash the generator: Plug the electric drill into the generatorreceptacle. (Cordless drills do not work) If the drill is reversible, move the direction switch to the forward position. Start the generator. While depressing the trigger on the drill, spin the drill chuck in reverse direction.

To restore the small amount of residual magnetism necessary to begin voltage buildup, connect a 12 volt battery to the exciter field while the generator is at rest, as follows: Remove exciter field leads F+ and F- from the voltage regulator.

POWER GENERATOR LOW VOLTAGE


How long has the unit sat? I doubt the problem is the rotor, but it is possible. Disconnect the brush wires, (note where they go for polarity) Put an ohm meter across both rings and read the value, then go from each ring to ground = 0Mohms between rings approx 1ohm or less. Then check the stator output wires the same way. If you have DC voltage on the brush wires then your AVR is working, it is trying to flash the rotor field.

Honda eu3000is generator surges


Inverter Generator Benefits
  • The EU3000 series generators are inverter generators. The generator features an alternator, which produced high-voltage, multi-phase AC power. This power is converted to DC power and then converted back to AC. This process is controlled by a microprocessor and is necessary to provide stable, consistent power capable of running equipment sensitive to power surges. This type of generator provides higher fuel efficiency and lower operational noise ratings in a lighter model than home and work generators produced by Honda.

EU3000i Handi Specifications
  • The Honda EU3000i Handi is a 3,000-watt inverter generator that features wheels, folding handle and a recessed convenience light. The engine is a Honda GX160, which features a 163-cc displacement. The AC output is 120 volts, with an average rating of 2,600 watts and a maximum production of 3,000 watts. There are three receptacles to include a 20A, 125-volt duplex and a 30A, 125-volt locking plug. The DC output is 12 volts and 100 watts. The EU3000i can hold 1.56 gallons of unleaded fuel, which will provide consumers with 3.6 hours of run time at 25 percent load for 7.7 hours.

CHARGING
DESCRIPTION - CHARGING SYSTEM
The charging system consists of:
† Generator
† Decoupler Pulley (If equipped)
† Electronic Voltage Regulator (EVR) circuitry
within the Powertrain Control Module (PCM)
† Ignition switch (refer to the Ignition System section
for information)
† Battery (refer to the Battery section for information)
† Battery temperature sensor
† Voltmeter (refer to the Instrument Cluster section
for information)
† Wiring harness and connections (refer to the
Wiring section for information)
† Accessory drive belt (refer to the Cooling section
for more information)
OPERATION - CHARGING SYSTEM
The charging system is turned on and off with the
ignition switch. The system is on when the engine is
running and the ASD relay is energized. When the
ASD relay is on, voltage is supplied to the ASD relay
sense circuit at the PCM. This voltage is connected
through the PCM and supplied to one of the generator
field terminals (Gen. Source +) at the back of the
generator.
The generator is driven by the engine through a
serpentine belt and pulley or decoupler pulley
arrangement.
The amount of DC current produced by the generator
is controlled by the EVR (field control) circuitry
contained within the PCM. This circuitry is connected
in series with the second rotor field terminal
and ground.
A battery temperature sensor is used to sense battery
temperature. This temperature data, along with
data from monitored line voltage, is used by the PCM
to vary the battery charging rate. This is done by
cycling the ground path to control the strength of the
rotor magnetic field. The PCM then compensates and
regulates generator current output accordingly to
maintain system voltage at the targeted system voltage
based on battery temperature.
All vehicles are equipped with On-Board Diagnostics
(OBD). All OBD-sensed systems, including EVR
(field control) circuitry, are monitored by the PCM.
Each monitored circuit is assigned a Diagnostic Trouble
Code (DTC). The PCM will store a DTC in electronic
memory for certain failures it detects. Refer to
On-Board Diagnostics in the Electronic Control Modules(
Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL
MODULES/POWERTRAIN CONTROL
MODULE - DESCRIPTION) section for more DTC
information.
The Check Gauges Lamp (if equipped) monitors:
charging system voltage, engine coolant temperature
and engine oil pressure. If an extreme condition
is indicated, the lamp will be illuminated. This is
done as reminder to check the three gauges. The signal
to activate the lamp is sent via the PCI bus circuits.
The lamp is located on the instrument panel.
Refer to the Instrument Cluster section for additional
information.
VOLTAGE REGULATOR
DESCRIPTION
The Electronic Voltage Regulator (EVR) is not a
separate component. It is actually a voltage regulating
circuit located within the Powertrain Control
Module (PCM). The EVR is not serviced separately. If
replacement is necessary, the PCM must be replaced.
OPERATION
The amount of DC current produced by the generator
is controlled by EVR circuitry contained within
the PCM. This circuitry is connected in series with
the generators second rotor field terminal and its
ground.
Voltage is regulated by cycling the ground path to
control the strength of the rotor magnetic field. The
EVR circuitry monitors system line voltage (B+) and
battery temperature or inlet air temperature sensor
(refer to Battery Temperature Sensor or Inlet Air
Temperature Sensor for more information). It then
determines a target charging voltage. If sensed battery
voltage is 325 mv or lower than the target voltage,
the PCM grounds the field winding until sensed
battery volage is 325 mv above target voltage. A circuit
in the PCM cycles the ground side of the generator
field up to 250 times per second (250Hz), but
has the capability to ground the field control wire
100% of the time (full field) to achieve the target
voltage. If the charging rate cannot be monitored
(limp-in), a duty cycle of 25% is used by the PCM in
order to have some generator output. Also refer to
Charging System Operation for additional information.
REMOVAL
The electronic voltage regulator is not a serviced
separately. If replacement is necessary, the PCM
must be replaced.

It is possible that your voltage regulator is shot but before purchasing the volt regulator try flashing the fields first and make sure the brushes and rings are clean.
