What to do if my Forney Battery Charger has no reading on the ammeter?

  Robert HallAug 14, 2025
  If your Forney Battery Charger shows no reading on the ammeter, several issues could be the cause. First, ensure the charger is plugged into a working A.C. outlet and that there is power at the receptacle by checking the fuse or circuit breaker. Also, check the clips for a secure connection to both the battery and the frame. Reversed connections can also cause this issue, so unplug the charger and reverse the clips. The battery itself might be defective and unable to accept a charge, so have it checked. Finally, be aware that the ammeter may not show activity if you are using the 2 amp charge rate.

What to do if Forney Battery Charger short or no start cycle when cranking engine?
- A
  Andrea KellyAug 17, 2025
  If you experience a short or no start cycle when cranking the engine with the Forney Battery Charger, several factors could be responsible. You might be drawing more current than the engine start rate allows. Ensure you wait 3 minutes (180 seconds) between crank attempts. Check that the clips are making a good connection at the battery and frame, and verify that the A.C. cord and any extension cords are securely plugged in. Also, confirm that the receptacle has power by checking the fuse or circuit breaker. The charger may be overheated, requiring the thermal protector to reset, or the battery might be severely discharged; in this case, charge it for 10 to 15 minutes at the manual charge rate.

Why does the ammeter reading stay high on my Forney 52726 Battery Charger?
- E
  Evelyn CastroAug 21, 2025
  If the ammeter reading remains high on your Forney Battery Charger, it could be because the battery is severely discharged; in this case, continue charging the battery for two more hours. Alternatively, the battery voltage might be incorrect. If the problem persists, have the battery checked and verify that the voltage settings or output ratings on the charger are correct.

Why is my Forney Battery Charger making a clicking sound?
- V
  veronicahaleyAug 26, 2025
  The clicking sound from your Forney Battery Charger could be due to several reasons. The circuit breaker might be cycling, so check the charger settings. The battery could be defective, so have it checked. Shorted battery cables or clips could also be the cause; inspect them and replace if necessary. If the battery is severely discharged but otherwise good, allow charging to continue until it recovers sufficiently. Lastly, reverse connections at the battery can cause this issue; turn off the charger and correct the lead connections.

  Daniel HartAug 28, 2025
  If your Forney Battery Charger does not turn on when properly connected, the issue might be a dead A.C. outlet. Check the fuse or circuit breaker supplying the outlet. It could also be due to a poor electrical connection, so inspect the power cord and extension cord for loose plugs.

Why ammeter reads less than selected charge rate when charging a discharged battery by Forney Battery Charger?
- M
  misty25Sep 5, 2025
  If the ammeter reads less than the selected charge rate when charging a discharged battery with your Forney Battery Charger, the extension cord might be too long or the wire gauge too small; try using a shorter or heavier gauge extension cord. Alternatively, the battery may have a weak cell or sulfated plate; a sulfated battery will eventually take a normal charge if left connected. The battery might also be only partially discharged, in which case you should continue charging it.

Why is the measured current much lower than what was selected on my Forney 52726 Battery Charger?
- P
  Paula JosephSep 9, 2025
  If the measured current is much lower than what was selected on your Forney Battery Charger, it is likely because the charger has reached the maximum voltage and is reducing the current. This is a normal condition.
