Will a Faulty Motorcycle Rectifier Burn Out the Battery?
1 Answers
If a motorcycle's rectifier is damaged, it may cause the charging voltage to become too high, which could potentially puncture the battery, leading to battery damage, swelling, or even bursting. Function of the Rectifier: The motorcycle rectifier's role is to convert the vehicle's alternating current (AC) into direct current (DC) for use by electrical devices. The current required by motorcycle electrical devices is generated by the magneto. Without passing through the rectifier, the voltage would fluctuate with the engine's speed, being directly proportional to it. Electrical devices cannot withstand this type of current and are easily damaged. Methods to Determine Rectifier Failure: When accelerating to increase engine speed, if the voltage remains unchanged, it is normal. If the voltage suddenly spikes or drops significantly, the rectifier is not functioning; After starting the engine, disconnect the positive terminal of the battery. If the engine does not stall but the circuit voltage exceeds 14.5V, or even reaches above 18V, then the rectifier is damaged; Using a digital multimeter to directly measure the rectifier can determine whether it is effectively rectifying.
