SOURCE: No voltage output

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.

SOURCE: no output voltage at all

The generator needs to be 'flashed' to bring back the excitation for output. Is this something you can do? Let me know and I can help you...

SOURCE: generator voltage too low

check engine speed by the sound...if normal then check AVR card...replace it...
if not normal rase it...

chek brushes...if they seemed ok then replace AVR card

SOURCE: no output from my generator

Check the capacitor in the generator head. Will onpen or short cause loss of excitation voltage. Just checked my GENERAC ( no output) and sure enough the cap is shorted.

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
  • Generator pulley
  • Battery junction box (BJB)Mega Fuse
  • Battery junction box fuse:
    • 11 (20A)
  • Central junction box (CJB) fuse:
    • 30 (30A)
  • 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 .

    Your whole problem is the alternator is not charging , a couple tests with a volt meter would tell you !

Generator running but not electrical output, why


generators need a circuit to excite the windings in the alternator as there is no residual magnetism for this to happen
Same as on a car alternator where the battery supplies that power
there will be a small section that generates this power requirement before the full voltage cuts in
as most makes of generators ( invertors excepted) use the same basic schematics you should be able to down load the diagram from the net for your make or from a make the same rating as yours

I have a 10KW SIEMENS generator Model #0059090 - Cat#ASGNO10RBS, it was installed May 26-2011.Generator workrd fine after runing all the test required. We had a very short outage less then a minute, after...


Most of those chargers have a fuse in line between the battery and the charger which you should check. They are two stage chargers meaning when there is a large voltage drop, they go to a high rate charge until battery voltage reads about 14.3 - 14.6 VDC then drops to a float volatge and normal float voltage should be about 13.33 VDC. When they go to a high rate the light turns red, when they go to float the light turns green. When the fuse blows the light stays green because it doesn't see any voltage but the charger isn't doing any work.

Battery light is on. i changed the battery and altinator


If the battery light is on, this is an indication tha the generator is not working.
A simple check of the generator is to measure the voltage over the battery in 2 steps. The battery voltage - engine not running = 12VDc
voltage - engine running = around 14.2VDc or defenately higher than the voltage in situation where the engine is not running.

If the generator is is ok the voltage measured over the battery wil increase as a result of charging.

If no increase of voltage - charger defective - or eventually poor cable connections between the charger unit and "the engine".

It will not charge the starter battery.


Do you have a volt meter so that you can check battery output when unit is running. The charge rate on most small engines is about 3 amp so it will not charge very fast. If you have a battery charger I would disconnect negative cable from battery, check voltage on battery then hook up charger for a couple hours. Recheck voltage.Then leave battery neg. cable off overnight and check voltage again the next day.You may have a bad battery that wont hold charge. If it holds charge overnight then I would hook neg. cable back up and leave set for a day or two and recheck voltage. If voltage has dropped then you have something draining battery. Before I did anything to drastic I would clean all connections to battery and starter switch. If your system is really not charging you will have to replace starting diode. Good luck.

Battery does not stay charged on my 20kw generac generator


WAS A 110 VOLT CIRCUIT RAN TO IT FROM THE NORMAL UTILITY POWER OF HOME OR BUILDING IT FEEDS?
NORMALLY THIS IS DONE IN A SEPERATE CONDUIT FOR CONTROL WIRES.AND THE FEEDERS ARE IN ANOTHER CONDUIT.
WITH A DIGITAL TEST METER,CHECK FOR 120 VOLTS AT THE BATTERY CHARGER IN THE GENERATOR CABINET.USUALLY THERE IS A RECEPTICAL TO PLUG THE CHARGER INTO.
IF VOLTAGE IS PRESENT AT THE BATTERY CHARGER AND INDICATOR LIGHTS ARE ON, CHANGE METER TO DC AND CHECK FOR 13.8 VOLTS OUTPUT FROM THE BATTERY CHARGER.IF YOU HAVE OUTPUT VOLTAGE TO THE BATTERY,AND IT IS DEAD,CHANGE THE BATTERY..

HOPE THIS HELPS YOU,BEST OF LUCK.....

When I run my generator - a Yamaha EF2400S to my Zantrex Model MS2000, it will not accept the power to charge my batteries. The generator's voltage and frequency, when checked, are within acceptable...


the power coming from your generator is probably "dirty", full of spikes and surges from the generator. If it accepts shore power and not gen power, then the generator is the most likely cause. If the generator in unregulated, you are stuck, but it could have a failing voltage regulator board, or Yamaha may have a solution.
