Why don't my generator fg7000ma generate power or only half power

SOURCE: Generator will not generate electricity.

I assume it is a hand start genset. The most common problem if it has been sat for a while is rust on the ignition timing flywheel. If you take the pullcord housing off (recoil) then you will see a big flywheel with what can only be described as a big forked prong with a couple of wires on it. This flywheel should be stainless steel and rusts when sat around for a while without use. Its job is to complete the circuit to the spark plug every time the flywheel passes the forked prong at a given spot on the flywheel, the faster the wheel turns the faster the spark hence the engine runs quicker. Clean the rust off with a releasing agent (wd 40) hey presto!!!!!!!!!!!

Honda generators are very reliable and are easy to adjust. The best way to check for proper output is to use a meter that can check cycles and voltage. Set meter to htz or freq and adjust the engine governor to 60 cycles. When the engine is turning 3600 rpm it is at max power and the generator may be producing ac voltage ranging from 115 to 125 at 60 cycles. When you draw power from the generator the engine governor will try to overcome the stress and maintain 3600 rpm. The engine must be well maintained to produce full power. Service oil, filter, plug and valve adjustment. Some engines have a spark arrester installed in the muffler that may become blocked with carbon. If engine is producing full power and voltage/amps is low then check brushes, capacitors, and/ or voltage regulator. Most problems occur when too much power is requested from rated generator. Example, trying to connect an 1800 watt air compressor to generator. The compressor may draw double the stated wattage upon starting and cycling. For longest generator life, It is best to use only 75% of rated output. On an 1800 watt generator use max wattage 1350. If you actually need to use 1800 watts then the best generator would be a 2500 watt. enjoy

You need to trace out the power wires the come out of the genset. They will end up on a breaker. With a volt meter measure both sides of the breaker. If one side has voltage and the other side doesn't, then your breaker is opened. Press the breaker in closed to see if it actually closes. If it don't then you will need a breaker. However, if no voltage is being produced, it is possible that the voltage regulator let go.

Check the voltage regulator and any fuses or breakers.

SOURCE: generator starts but does not generate power

1. Check for any blown fuse and replace. It can be traced directly from the output lines.
2. Check field excitation. The field excitation is supplied by the battery to the excitation coil through a pair of carbon brushes. If the brushes are worn out, no excitation field is supplied and no output is generated. Replace carbon brush if found worn-out.
3. Use an analog multitester to check the continuity of the carbon brush and the field coil.
