LM317T Voltage Regulator with Pass Transistor

**Always follow the instructions in your repair manual when doing repair or maintenance work on Outdoor Power Equipment. Manuals can be found at the manufacturers website.** In this video I check the voltage and frequency at the outlets on a portable Briggs & Stratton Generator, and the RPM of the engine. I also change the engine oil. You really should get a repair manual for the generator your working on to see the electrical schematic and get the proper specs for the generator, but in the USA the voltage should be close to 120 or 240 volts depending on the type of outlet, and the frequency should be around 60 hertz. To get 60 hertz on most generators, the engine RPM should be close to 3600 RPM. Every generator can have different specifications, so a repair manual is really important for proper specifications and the electrical schematic is priceless. The engine on this generator uses a splash type oil system, so it doesn't have a oil filter to replace. You simple drain the oil and refill the engine with 32 ounces of fresh oil. It is important to warm up the engine to operating temperature before you replace the oil. Warming up the engine helps the oil flow better, and it causes contaminates in the oil to get suspended in the oil and drain out with the old oil. I always use a single grade oil in the warm season with air cooled engines. Single grade oil holds up better than a multi grade oil under high temperatures. Air cooled engines run at a higher temperature than a ...
