Why is my Schumacher Electric Battery Charger making a clicking noise?
If the Schumacher Electric Battery Charger is making a clicking noise, it could be due to several reasons. The circuit breaker might be cycling because of high capacity demands; in this case, stop the operation, wait for the unit to cool, and then resume. Other causes include a defective battery (have it checked), shorted battery clamps (check and replace if necessary), a severely discharged battery (allow charging to continue), or reversed connections at the battery (correct the connections).
