Schumacher has been producing automotive electrical products since 1946. Its an official supplier for the NASCAR auto racing brand and produces chargers, jump starters and inverters for NASCAR. Schumacher battery chargers are designed to work automatically, however issues can include the meter not working, noises and the charger not turning on. These kinds of problems can be rectified.
Step 1
Jiggle the clips and rock the clips backwards and forwards if theres no meter reading. The clips arent making proper contact.
Step 2
Try a different AC power outlet if the charger wont turn on when its connected. You can try another appliance -- a worklight, for example -- and see if that works. If the worklight wont come on, the problem is with the wall outlet, not the Schumacher charger. If the lamp comes on, try the charger again and wiggle the connections.
Step 3
Allow the charging to continue for up to 20 minutes if the charger makes clicking noises. The clicking can be the circuit breaker cycling and can indicate a defective battery, or a very discharged battery that isnt defective. If the clicking doesnt stops after about 20 minutes, the battery may well be bad and you should replace it.
Shut off the charger and reverse the battery connections if the battery has been replaced and the clicking continues. The leads are on the wrong poles.
Tip
- Humming is normal and is a characteristic of the transformer technology. Humming can occur even when the charger isnt hooked up to a battery.
