If your Schumacher Battery Charger isn't turning on when properly connected, the AC outlet might be dead. Plug in a lamp to check for voltage. Also, check the connections and rock them back and forth for a better connection. A poor electrical connection could also be the cause, so ensure everything is properly connected.
Why Schumacher Battery Charger has no meter reading?
If your Schumacher Battery Charger shows no meter reading, it could be due to a couple of reasons. The clips might not be making a good connection; try rocking them back and forth for a better connection. Also, ensure the AC line is plugged into the outlet. Another reason might be that the battery voltage is too low; in this case, rocking the clips and plugging in the AC line should also help.
What to do if Schumacher Battery Charger is making a clicking noise?
If your Schumacher Battery Charger is making a clicking noise, it could be due to several reasons. The circuit breaker might be cycling, possibly because it's in the wrong switch position. Another possibility is that the battery is defective, so you should have it checked. If the battery is severely discharged but otherwise good, allow charging to continue until the battery recovers sufficiently to take a charge; however, if it continues for more than 20 minutes, stop charging and have the battery checked. Also, ensure lead connections are correct and shut off the charger while correcting them.

Ensure charger, battery, and vehicle are compatible and read all instructions before use.
Follow procedures for cord/plug safety, unit damage, and unplugging before maintenance.
Guidelines for using extension cords, including pin compatibility, wiring, and AWG size.
Ensure ventilation, proper distance from battery, and avoid rain, snow, or placing charger directly above battery.
Wear eye protection, have water/soap ready, and wash skin/clothing if battery acid contacts.
Ensure assistance is available, maintain ventilation, and never smoke or allow sparks near the battery.
Remove metal items and avoid dropping tools onto the battery to prevent sparks or burns.
Charger must be grounded. Do not alter the AC cord or plug; ensure proper outlet installation.
Identify positive and negative battery posts and determine which post is grounded to the chassis.
Connect RED clip to POSITIVE post and BLACK clip to chassis/engine block (or vice versa for positive ground).
Unplug charger, remove clips (chassis then battery pole), and clean/store the charger.
Check polarity, attach a 24-inch cable to the NEGATIVE post, then connect the RED charger clip to POSITIVE.
Connect the BLACK charger clip to the free end of the cable, then unplug and remove clips after charging.
Select the correct charge rate for battery voltage. Charger has a dual self-reset circuit breaker system.
Ammeter shows amp draw; readings taper as battery charges. Monitor cold, shorted, or deep-discharge batteries.
Connect charger, set to 12V Engine Start, crank engine. Follow duty cycle and recharge if needed.
Calculate AH rating using Reserve Capacity or find it on the battery label.
Use formula: (AH x % charge needed) / amp setting x 1.25 = hours. Add time for deep cycle batteries.
Monitor charging regularly. Check electrolyte level. Bubbles indicate 80-85% charge; specific gravity should be 1.25-1.28.
Check clip connections, AC outlet, and electrical connections for proper function.
Verify switch position, check battery condition, or correct reverse connections.
