Why engine start does not work on Proseries PSW-70300A?
- M
  mitchellamySep 12, 2025
  The engine start function might not work due to several reasons: you may be drawing more than 300 amps, you may have failed to wait 3 minutes between cranks, the charger may be overheated, or the battery may be severely discharged. Consider the amount of current drawn. If it exceeds 300 amps, reduce crank time to less than 3 seconds. Allow a 3-minute rest period before attempting another crank. Ensure the charger vents are unobstructed to prevent overheating and allow the thermal protector to reset. For a severely discharged battery, pre-charge it for 10 to 15 minutes at the 40 Amp manual rate to aid cranking.

What to do if Proseries PSW-70300A is making audible clicking sound?

  An audible clicking sound from the charger can be caused by several factors: the circuit breaker cycling, a defective battery, shorted battery cables or clamps, a severely discharged battery (but otherwise good), or reverse connections at the battery. Check the charger settings to ensure they are correct. Have the battery inspected. Inspect the cables and clamps for shorts, replacing them if necessary. Allow charging to continue until the battery begins to accept a charge; if this takes more than 20 minutes, discontinue charging and have the battery checked. Turn off the charger and correct the lead connections.

  If the charger does not turn on when properly connected, it could be due to a dead AC outlet or a poor electrical connection. Check the AC outlet for an open fuse or tripped circuit breaker. Also, inspect the power cord and any extension cords for loose plugs.

Why ammeter reads less than selected charge rate on Proseries PSW-70300A?
- P
  Peter SwansonAug 28, 2025
  If the ammeter reads less than the selected charge rate when charging a discharged battery, this may be due to an extension cord that is too long or has too small of a wire gauge, a weak cell or sulfated plate in the battery, or the battery is only partially discharged. Try using a shorter or heavier gauge extension cord. A sulfated battery may eventually take a normal charge if left connected. If the battery does not charge, have it checked. Continue to charge the battery.

  If there is no reading on the ammeter, several issues could be the cause: the charger might not be plugged in, there may be no power at the receptacle, the clamps are not making a good connection to the battery, connections are reversed, or the battery is defective. Plug the charger into an AC outlet and check for an open fuse or circuit breaker. Ensure a good connection to both the battery and the frame, making sure connection points are clean. Unplug the charger and reverse the clamps if necessary. Have the battery checked.

Why is there no reading on the ammeter of my Proseries PSW-70300A?

  Monica KingSep 3, 2025
  If your Proseries Battery Charger shows no reading on the ammeter, several issues could be the cause. First, ensure the charger is properly plugged into a functioning AC outlet and that the outlet has power by checking the fuse or circuit breaker. Next, verify that the clips are making a secure and clean connection to the battery and frame, rocking them back and forth to improve contact. Also, make sure the connections are not reversed. If these steps don't resolve the issue, the battery itself may be defective and need to be checked. Finally, be aware that the ammeter may not show activity at the 4A charge rate.

Why is my Proseries PSW-70300A Battery Charger making a clicking sound?
- C
  campbellbriannaSep 5, 2025
  If your Proseries Battery Charger is making an audible clicking sound, it could be due to several reasons. The circuit breaker might be cycling, indicating incorrect settings, so check the charger settings. The battery could be defective and needs to be checked. Also, there might be shorted battery cables or clips, which would need to be inspected and replaced if necessary. If the battery is severely discharged but otherwise good, allow charging to continue until it recovers sufficiently. Finally, reverse connections at the battery can cause this issue; shut off the charger and correct the lead connections.

  Mary CarlsonSep 7, 2025
  If your Proseries Battery Charger's ammeter reading stays high, it could be because the battery is severely discharged; in this case, continue charging the battery for two more hours. Another possibility is that the battery voltage is incorrect; verify that the voltage settings on the charger are correct.
