My generator is a briggs and stratton 7kw prowered. connected to full propane tanks. i have not had any problems with the generator until this past weekend. the generator starts up fine, and then once it has been running for a few minutes the generator will cut out and almost die, sometimes back fireing. this occurs every few minutes until ultimately the generator dies.

I did find out that the inner slip ring was worn down. Still unknown why and the repair tech we took it to twice just replaced the brushes and never looked at the slip rings.

My solution, which has worked for over two months now (knock on wood) is as follows:

The slip ring on this unit can only be replaced by replacing the whole rotor assembly. I looked at the width of the brushes and the width of slip rings. The slip rings are twice as big as a brush. The solution was to move the brushes outward by one brush length. In order to do that, I had to turn the brush assembly around because of the extra plastic on the unit and space it out one brush length. Note: Still hook the wires as if the brush assembly was not turned around.

I used an old brush assembly and cut the two areas where the screws go through to make my spacers and it works perfectly.

Hi there,
Most home standby generators are setup to run once a week so as to keep the engine lubed up and the generator windings dry. So if yours is comming on once a week at about the same time and running for something like 15 minutes, that's what is going on.
On the other hand, if your generator is starting and the switch is transferring somewhat randomly, you could have a problem with the neutral connection in your system, the power could really be going out and coming back on, and/or the control board in your generator could be broken.

Regards,
Carl

SOURCE: Generator with Briggs & Stratton,no gas is getting in carburetor

The needle valve may be stuck which would not let gas into the carb. I don;t think rebuild kits are too expensive. Pull the carb and take it to a lawnmower repair shop and they should have the parts. Before that though pull the bowl and make sure it has gas in it. If no then remove the fuel line and make sure gas flows from it. If no then could be the fuel shutoff valve is not operating properly or junk in the gas tank is obstructing the line.

SOURCE: briggs and stratton generator keeps throwing the circuit breaker

Power tools CAN draw heavy loads if the voltage or frequency is off. Both of those CAN be a fault of the generator.

Check the frequency by plugging in a clock with a moving second hand and time it for 10 minutes against a quartz clock. ALSO do a voltage check with another voltmeter.

The 5500 Watt generator should hold 40 amps. Power tools with induction motors like some table saws take a large starting load near this value AND would be sensitive to low voltage AND especially low frequency, both of which will cause much higher current draw.

One MIGHT have to resort to put an oscilloscope on the output to make sure the waveform of the AC output is normal..
