Fortunately, a wire brush and some baking soda solution can neutralize battery acid and eliminate resistance. The byproducts of corrosion, anhydrous copper sulfate and lead sulfate, are also great insulators. If you hear a depressing click or buzz when trying to start the lawn mower engine, this might be due to a couple of problems.Ĭorrosion occurs in the presence of dissimilar metals, sulfuric acid, electricity and water. If the interlock is good and the battery is good, getting enough juice to the starter motor can be a problem. Use your DMM to trace the interlock circuit for repair or adjustment. If the contacts are bent, broken or corroded, or if mice have chewed through the wiring, the interlock won’t enable the starter motor - no matter how good the battery is. Most starter interlock switches on lawn mowers are located under the seat or in the handle. If the battery is good, something else might be interrupting the starter signal, like the starter interlock. Interlock ProblemsĪt the beginning of the mowing season, and after sitting for months in winter storage, lawn mower batteries are often found to be dead, but that’s not the only reason for a no-start condition. Here are a few ways to tell whether it’s time to change the battery or look further into your lawn mower’s electrical system for the source of the problem. A fully charged 12V battery should read at least 12.6 volts, while a moderately discharged battery might only read 10.5 volts. Before you condemn the battery, take a voltage reading with a quality digital multimeter (DMM). Maybe the culprit is your lawn mower battery - or maybe it’s not. But what if you can’t start your lawn mower? Electric-start lawn mowers and other types of power equipment sure are convenient, and they’ve saved untold numbers of shoulders from rope-starting.
