Generator not charging - Hammering

http://cdn.powerequipment.honda.com/pe/pdf/manuals/31ZB4770.pdf Won't charge? Charge what? This generator has bo battery charging capability.

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.

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

Need to change the flux capacitor.

Generally that indication implies generator failure. Generator failure can come in multiple forms. A faulty ground will cause the generator not to charge and potentially burn it up. A severed phase wind (remember, your alternator is really a three-phase generator with a six pulse front end rectifier set) will cause the light to intermittently come on along with weak charging output. A voltage regulator failure will cause zero field current in the rotor. A brush failure will also cause a generator failure light to come on and stay on. A rectifier failure (any of the six) will cause the generator not to charge properly and turn on the MIL and generator failure indicator (looks like a battery). The condition of the battery can also cause generator failure, if the battery is defective (buckled plates, weak electrolyte, low water, etc.) it will place a very high load on the generator continuously, causing it to 'full field' the rotor which can cause the rotor to overheat and fail. Never run a generator without the battery terminals connected as this will cause it to fail quite spectacularly. Do not attempt to verify output of the generator with the battery terminal leads disconnected.

If generator failure is indeed the cause, find out why. Generators rarely fail. When they do, it usually is caused by poor ground connections, corroded battery terminals, high continuous loads, electrical faults and poorly-wired ancillary equipment, such as head units, amplifiers, inverters, etc. Always check all these out when replacing the generator. Never run a generator without the battery terminals connected as this will cause it to fail quite spectacularly.

Most of time, diesel generator runs abnormally because of battery long time no maintenance or the deviation between components . In reality, it can be back to normal as long as you make a little adjustment.
Regulator adjustment: If the faults like charging ammeter pointer stops movement, charging ammeter is too large or small occur during the process of using diesel generator , it needs a regulator to adjust. If battery charging current is too large, it will shorten the service life. If it is too small, it can't give battery charged on time. If the charging ammeter shows the charging current is too large when diesel generator works, you should adjust the current limiting spring of regulator to shorten the spring. The current should be reduced. Or vice versa. In the process of adjusting, not too hard, light touching until it meets the requirements.
Oil pressure adjustment: In general, diesel generator has two lubrication methods. One is pressure lubrication, the other is splash lubrication. Diesel generator lubrication quality is closely connected with oil pressure. Therefore, when the diesel generator is at work, the oil pressure must be controlled within the valid range.

Replace battery with your choice of 12v products considering physical size, amp range and warranty. Lawn tractor batteries seem to have the least life/duty cycle. There are two methods of charging the battery used by Coleman. One is to charge the battery with charger/alternator coils installed under flywheel of the engine and second is to charge with built-in circuit in generator itself. Examine your wiring diagram to discover which you have. Simple test with volt meter will show if system is charging. Test voltage at battery with engine off, then start engine and retest looking for slightly higher voltage indicating charge. The charging system is like a trickle charger and not like your auto with initially high amp charge then taper to minimum. If your run your generator for long periods of time and you feel that the battery is being overcharged, then rig a switch to stop charging after one hour or longer. Good holiday

Generator with Integral Rear Mount Voltage Regulator, Internal Fan Type With the key in the RUN position, voltage is applied through the charge indicator lamp I circuit to the voltage regulator. This turns the voltage regulator on, allowing current to flow from the battery sense A circuit to the generator field coil. When the engine (6007) is started, the generator (GEN) (10346) begins to generate alternating (AC) current which is converted to direct (DC) current by the rectifier internal to the generator. This current is then supplied to the vehicle's electrical system through the battery positive voltage (B+) terminal located on the rear of the generator. Once the generator begins generating current, a voltage signal is taken from the stator and fed back to the voltage regulator S circuit, turning off the charge indicator/lamp. With the system functioning normally, the generator output current is determined by the voltage at the A circuit. This voltage is compared to a set voltage internal to the voltage regulator, and the voltage regulator controls the generator field current to maintain proper generator output. The set voltage will vary with temperature and is typically higher in the winter than in the summer, allowing for better battery recharge. With the system functioning normally, the generator output current is determined by the voltage of the A circuit (battery sense voltage).

A fuse link is included in the charging system wiring on all vehicles. The fuse link is used to prevent damage to the wiring harness and generator if the wiring harness should become grounded, or if a booster battery with the wrong polarity is connected to the charging system.

The Mitsubishi 215-ampere generator is an internally regulated, brushless unit that is self-current limiting and temperature compensating. The regulator is integral with the generator and the fan is external.

VISUAL INSPECTION CHART Mechanical Electrical

• Before attempting to test a battery, it is important to give it a thorough examination to determine if it has been damaged.

• Batteries are tested to determine the state of charge and ability to crank an engine. The result of these tests is to show that the battery is either good, needs recharging, or must be replaced.

• Preliminary checks to the charging system should be made regardless of the fault condition. These checks include:
  • Check the fuses/fuse links to the generator to ensure that they are not burned or damaged. This condition, resulting in an open circuit or high resistance, can cause erratic or intermittent charging system concerns.
  • Check battery posts and cable terminals for clean and tight connections. Clean the posts and the cables to ensure good electrical contact.
  • Check for secure connections at the generator output, voltage regulator and engine ground. Also check the connection at the power distribution point.
  • Check the generator drive belt to ensure proper tension and no slip between the generator pulley and the drive belt. Refer to Section 03-05 in the Powertrain, Drivetrain Manual.
  • Check battery for full charge.

• Before performing charging system tests on the vehicle, note conditions such as: slow cranking, discharged battery, charge indicator lamp stays on with engine running, charge indicator lamp does not illuminate with ignition switch in RUN and engine not running, etc. This information will aid in isolating the part of the system causing the symptom.
• When a relatively new battery is discharged, test for current drain. The following are some of the most common current drain concerns:
  • Glove compartment lamp stays on with the door closed.
  • Engine compartment lamp stays on constantly.
  • License plate lamp or interior lamp stays on constantly.
  • Other electronic component concerns.

Hi!

Take a look on the generator, thats the one charging the battery, the coals in the generator might be needed to be replaced, there are two of them, Also check the two cables from the generator so they arent dameged or broken.
You can take the bike to a repaire shop and ask them to help you measure if the generator gives enough power to charge the battery or on, the can measure the power on the generator and they can measure the power coming to the battery.

Im sure the the problem is the generator or the cables from the generator

Good luck
Nic

It's not charging, or the battery won't hold a charge? Get a multimeter and test the generator with the bike running, should be 13.5-14.5 volts. If you get this, you need a battery, if not need to find the bad component in the charging system.

Try reversing the polarity of the battery you're using to flash the generator. Also try running the generator for about 30 min with a load on it after flashing.
