BUFFALO TOOLS 2000 WATT GENERATOR 12 VOLT OUTPUT BUT NO AMPS WILL NOT EVEN LIGHT A 12 VOLT TEST LIGHT BUT VOLT METER READS 12 V.D.C. WHAT IS WRONG ? PLEASE HELP.LABEL SAYS FOR 12 VOLT BATTERY CHARGING

P/V=A

The panel is rated 6 watts at 12 volts 12 / 6 = 0.5 Amps

So in full sun the panel "should" produce 1/2 Amp at 12 Volts.

What type of 12V bulb and what is its current rating?

Could be lost exciter current. This is how to restore it - Connect 16 or 18 gauge wires to a 12 volt battery. With generator running, insert bare ends of wires into AC outlet - one to Hot, the other to Neutral. Insert and remove quickly. There should be a flash and power will be restored. If not, repeat until you get that flash and output current restored. Using light gauge wires is so that if you are too slow to remove them once AC is restored. they will burn out before the battery suffers from the AC incoming. Be quick and be careful.

You may be asking too much of the unit; the 5800 watts a which it is spec'd, may be a 'peak' power rating which may be 15-20% higher than its continuous rating. 30 Amps at 220 volts implies 6600 watts which is higher than even the peak power rating. I would expect the unit to produce ~4800 watts continuous or around 22 Amps.
Decided to check my statements and found this, which I quote:
Generator Volts AC (60Hz) 120/240 Max. Output Current 5800W-48.3A/24.2A Rated Output Current 4800W-40A/20A Volts DC (AMPS) 12 (8.3)

To find out which is bad, you have to check the maximum output of the generator. To do this, you'll need a good voltmeter and a jumper wire. First, remove both "A" and "F" terminal wires. One of the wires is a hot wire so don't let it short to the frame. Then set your meter's function switch to DC VOLTS with a range of 50 volts or greater. Connect the positive meter lead to the "A" terminal and the negative meter lead to an engine ground. Start the engine and run it at about 2000 RPM. MOMENTARILY connect a jumper lead from the engine ground to the "F" terminal. Your volt meter should read 25 to 30 volts. If not, polarize the generator but MOMENTARILY shorting the battery positive post with the "A" terminal and recheck the maximum output test. If you do not have at least 25 volts out of the generator, you need to service the generator. If you do have 25 or more volts from the generator, your regulator is probably bad.

To test the chargeing system on your bike. First, text the battery. Unless it is "brand new" there is always the posibility that your battery is the problem. This is especially true on an Ironhead Sporty due to the vibration. Take it to an automotive parts store and ask them to load test it.

The first thing we want to do is to "polarize" the generator. Using a jumper wire, MOMENTARILY touch the wire from the "A" terminal to the positive terminal of the battery. Just make it spark, that's all.

Now, with the battery FULLY CHARGED, connect a DVOM (digital volt ohm meter) to the battery. Red meter lead to the positive and black meter lead to the negative. Put the meter's function switch in DC VOLTS, 20 VOLTS or greater scale. Start the engine bring it to a high idle. The meter should read 14.5 to 15.0 volts. If not, test the generator.

First, remove all the wires from both the "A" and the "F" terminals. put your meter's function switch to DC VOLTS, 50 VOLTS or greater. Connect the red meter lead to the "A" terminal and the black meter lead to a good ground. Start the engine and bring the revs up to about 2000 rpm. MOMENTARILY, connect a jumper lead form ground to the "F" terminal of the generator. Your volt meter should read 25-30 volts.

If your generator output is good, you need to replace your regulator. If the output of the generator is zero or low, you need to service the generator. Check the brushes to make sure they're not worn and you may need to recondition the communtator surfaces.

Good luck

wow, that is high, i would think voltage regulator is faulty also

Check the voltage with a meter in all the recepticles with your meter leads in the left and right slots on the plugs. Is that 184 volts AC there? If so, your gen has big problems with the voltage regulator. Let me know what you read. You can check the right slot of each plug to the round ground hole on the plug too, should be 120 volts there.

Most likely there is a bad diode in the alternator. needs tested.

Do a ohm test on armature slip rings with brushes removed.You should have continuity between rings but not between either ring and shaft.
