I have a Briggs & Stratton Generator 5550Watt model 030253 That is showing an output of only 4.6 Volts at the pannel. Suggestions???

No wiring diagram available from Briggs. Try re-magnetizing the rotor. No AVR or Capacitor listed in the parts list.

Disconnect the wires to brushes ( pay attention to the order) and apply 12vdc to brushes. Positive goes to brush closest to the bearing. Start the generator and check for output. If output is normal run the unit a few minutes to ensure re-magnetization then shut down normally. After shut down disconnect the 12 vdc source and re-install the previous disconnected wires. Now re start the generator and test for output should be okay provide there is no problems with the alternator. If no output during the above re-magnetization then your rotor windings my burned out.

Usually the cause of slightly low voltage like this is that the engine is not running at full operating RPM. Find the high speed adjusting screw on the govenor linkage and adjust the engine RPM until the output is 220V - 240V

I'll take guess here, broken ring. You did mention where it was spitting oil from? GB...stewbison

Hello; The Briggs engine front case is shaped to accommodate the internal mounting of the Alternator section. A service manual for this model would be very helpful. I believe you need to dismantle the back of the Alternator where the outlets are and then the outer case with the stator windings in it. This will leave the rotor ( the long shaft with windings on it ) which will be attached to the output shaft of the engine by some coupling device the you must dismantle. John

Can you manually adjust the voltage on the generator without load?? If you have 120/240 60hz output on it and you are not overloading the unit (amperage), then it may be as simple as adjusting whats called your gain setting for your voltage regulator. Obviously you are seeing what happens when it is set too low. Trying raising that setting until it becomes unstable then back it off. Unstable meaning voltage starts jumping all over.

Check your output voltage and frequency on the generator when you are connected to it.

Probably about 750cc / near 3/4 of a quart. Make sure generator is on level surface, add oil in small amounts and check using dipstick until shows full.

You may have exciting field broken. Look for a fuse or wire break.

check

avr / brushes if it has them

if not capacitor and diodes on the end of the armature

here is the link that you can view and print the owners manual from...
