How to Troubleshoot a Briggs & Stratton Electrical Engine
Troubleshooting a Briggs & Stratton Electrical Engine
- 1). Remove the six bolts that attach the maintenance cover on the top of the engine, using a ratchet. Remove the maintenance cover and locate the engine's 12-volt battery. Check the two leads connected to the battery's terminals. Make sure the leads are free of corrosion and firmly connected to the battery. Wearing gloves and goggles, press the positive and negative leads of your ohm meter to the corresponding contacts on the battery. If the leads appear to be in good shape but no charge is present, the battery needs to be recharged or replaced.
- 2). Unscrew the engine's leads from the battery and lift the battery from its protective cradle to expose the inner workings of the engine. Make sure the power switch is in the off position and no power is flowing to the engine. Feel the drive shaft that leads from the underside of the engine and exits the outboard's housing at the base of the motor's propeller. It is normal for a fine film of oil-based lubricant to coat the driveshaft. If there is none present, the entire outboard must be taken to a licensed dealer or repair shop for servicing. Lubricant will need to be applied within the engine's housing as well as within the outboard's housing.
- 3). Inspect the lubricant for drops of water. This engine is designed to be sealed from the elements and if water seeps into the engine, damage may occur. If you find water in the engine and it is not working, the engine might require professional repair or replacement.
- 4). Turn the outboard's propeller by hand. If it will not turn, the stator within the engine has seized and must be professionally repaired. If it will turn, albeit sluggishly, intermittently, or with a loud grinding noise, the linkage between the propeller and the driveshaft has been penetrated by waterborne particulate, sand, dirt or other sediment.
- 5). Remove the bolts holding the lower half of the outboard housing from the upper half, using a ratchet. The lower half of the housing will contain a universal joint which connects to the driveshaft. This universal joint will lift away, allowing the propeller to be unscrewed from a reverse-threaded central screw.
- 6). Scrub the universal joint, central screw, and propeller with a degreasing agent in a clean environment. Every speck of dirt and crusty build-up must be removed. Allow the degreasing agent to dry, then scrub it off with water. Allow the water to dry, then spray all components with high quality lubricant before re-assembling the lower half of the outboard housing and reattaching it to the upper half of the housing. Return the battery to its cradle, screw the leads tightly into place, bolt the maintenance cover back into place, and attempt to start the engine.
