SOURCE: portable generator low voltage

85 volts represents residual voltage. It is possible that your unit sat for an extended period and lost it's magnetism or the excitation system failed under load. check your manual for a procedure to "flash the field". If that is not successful, e-mail me and I'll tell you how to trouble shoot the failure.

SOURCE: voltage output is only 50 volts instead of 120 volts

More than likely your voltage regulator is out. The generator produces electricity, so you know the rotor and stator are OK. The 50 volts comes from the magnets permanent properties. The reason you are not getting 120 is because rotor or electron magnet is not getting any power supplied to it, which it needs to produce the amount of electrons you need to have 120vac. Make sure your engine is running at 60 hz first, and you should ohm out the windings and circuits that connect to your regulator.

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

SOURCE: Honda EMS 4500 Generator - High Voltage Problem

As far as I can tell on the wiring diagram for this generator there is no voltage regulator unless it's incorporated with the auto throttle unit.
To lower the voltage you need to lower the speed of the generator engine. To do this there should be a screw on top of the engine under the tank when your facing the recoil. This screw presses on a arm that controls your governor. Turning it in (righty tighty) will increase rpms, turning it out will lower them. You should see the voltage change on the voltmeter.

SOURCE: I have a Honda EB5000 Generator with no a/c output

Is this run on a xfer switch, have items just plugged into the generator or just run into an outlet. If on a xfer switch if not it could back fed electricity to the generator and fried it.

How do I fix my ups back-up with low voltage output, 175 volts only instead of 220 volts?


I would suggest that the battery is exhausted and needed to be replaced.

What is causing the battery to drain?


Running the car will drain the battery it if it's not charging ! An if your charging light is on it isn't charging ! Did you check power an grounds on the alternator ? There is a single heavier wire on the back of the alternator, this should have battery voltage ! You may want to take this to a ASE certified repair shop !
Functionality
With the ignition switch in the RUN position, voltage is applied through the warning indicator I circuit 904 (LG/RD) to the voltage regulator. This turns the regulator on, allowing current to flow from battery sense A circuit 35 (OG/LB) to the generator field coil. When the engine is started, the generator begins to generate alternating current (AC) which is internally converted to direct current (DC). This current is then supplied to the vehicle's electrical system through the output (B+) terminal of the generator.
Once the generator begins generating current, a voltage signal is taken from the generator stator and fed back to the regulator S circuit 4 (WH/BK). This voltage feedback signal (typically half the battery voltage) is used to turn off the warning indicator.
With the system functioning normally, the generator output current is determined by the voltage of the A circuit 35 (OG/LB). The A circuit 35 (OG/LB) voltage is compared to a set voltage internal to the regulator, and the regulator controls the generator field current to maintain the correct generator output.
The set voltage will vary with temperature and is typically higher in cold temperatures and lower in warm temperatures. This allows for better battery recharge in the winter and reduces the chance of overcharging in the summer.
Battery Positive Output (B+) Circuit 38 (BK/OG)
The generator output is supplied through the battery positive output (B+) terminal on the back of the generator to the battery and electrical system.
I Circuit 904 (LG/RD)
The I (ignition) circuit 904 (LG/RD) is used to turn on the voltage regulator. This circuit is powered up with the ignition switch in the RUN position. This circuit is also used to turn the charging system warning indicator on if there is a fault in the charging system operation.
A Circuit 35 (OG/LB)
The A (battery sense) circuit 35 (OG/LB) is used to sense battery voltage. This voltage is used by the regulator to determine generator output. This circuit is used to supply current to the generator field (rotor). The amount of current supplied to the rotor will determine generator output.
S Circuit 4 (WH/BK)
The S (stator) circuit 4 (WH/BK) is used to feed back a voltage signal from the generator to the regulator. This voltage is used by the regulator to turn off the charging system warning indicator. The S circuit is fed back externally on external mounted regulator generators.
Visual Inspection Chart Mechanical Electrical
  • Battery case, posts, hold-down clamp, cables and connections
  • Generator drive (serpentine) belt for condition and tension to make sure there is no slip between the belt and the pulley. For additional information, refer to Section 303-05 .
  • Battery charge

  • Circuitry
  • Charging system warning indicator
  • Cables
  1. Check the operation of the charging system warning indicator lamp (instrument cluster). Normal operation is as follows:
    • With the ignition switch OFF, the charging system warning indicator should be OFF.
    • With the ignition switch in RUN and the engine off, the charging system warning indicator light should be on.
    • With the engine running, the charging system warning indicator light should be off.
  1. Verify the battery condition. Refer to Section 414-01 .

Adustments engine speed low rpm


You cannot adjust the voltage output. All generators are rated for 110-125 volt recepticals and usually have at least one 220-240 volt receptical for special appliances that require it such as water heaters, pumps, welders, air conditioners. When one of these higher draw appliances is connected and they begin to draw amperage, the gas engine will automatically increase rpm to produce enough amps. If your generator gauge is showing low voltage such as 60,80 or 90volts for example, then you have overloaded the generator and blown a capacitor, resistor or similar item.

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.

Back up generator 240 volt output is off balance?


So there is a problem. Where are you measuring voltage?
Say there is L1 - N - L2. Line1 to Neutral is 120 volts, Line2 to Neutral is also 120 volts, Line1 to Line2 is 240 volts. N or Neutral ( the grounded conductor ) is center tap between line 1 and 2.
With this system, the N wire carries the unbalanced load in amperes .
Now we are talking of L1 and L2 and amperes. When L1 and L2 are conducting 10 amperes each, N carries 0 amperes, Line1 and L2 are balanced. When L1 carries 10 amperes and L2 carries 5 amperes, Line1 N carries 5 amperes, the difference of L1 and L2. This is normal.
When there is a problem with a loose connection on N, there is a resistance and will not carry the unbalanced load normally, the voltages will Chang's under load, the problem will worsen with time, a fire hazard, connected loads may burn up from excessive voltage or not work at all.
Bottom line: Make sure the N line ( white wire ) is tight at every connection and inspect for overheating damage. You may have to open the generator connections panel to check there too.
