How to fix no reading on the ammeter of DieHard Battery Charger?
If there's no reading on the ammeter, it might be due to poor clamp connections to the battery or frame. Ensure the connecting points are clean and have good contact. Also, note that the ammeter may not show any activity at the 2-amp charge rate.
What to do if DieHard 200.71240 ammeter has no reading and fan is not working?
If there's no reading on the ammeter and the fan isn't working, there might be no power at the receptacle or the AC cord and/or extension cord is loose. Check for an open fuse or circuit breaker supplying the AC outlet. Also, check the power cord and extension cord for a loose-fitting plug.
Why does my DieHard 200.71240 circuit breaker cycle on and off?
The circuit breaker cycles when the current draw is too high. This can be due to shorted battery clamps, a shorted battery, reversed charger leads, or the Volt/Amp Selector Switch being set to the START position. Separate the clamps and inspect the cables for wear, replacing them if necessary. Have the battery tested by a qualified service dealer. Ensure the connections are correct and the Volt/Amp Selector is properly set.
What to do if my DieHard Battery Charger ammeter reads less than selected charge rate?
If the ammeter reads less than the selected charge rate when charging a discharged battery, the extension cord might be too long or the wire gauge too small. A weak cell or sulfated plate in the battery, or the battery being only partially discharged could also be the reason. Try using a shorter or heavier gauge extension cord. If the battery has sulfated, it may eventually take a normal charge if left connected. If the battery does not charge, have it tested by a qualified service dealer. You can also continue charging the battery.
Why does my DieHard 200.71240 have a short start cycle?
A short start cycle when cranking the engine can happen if you're drawing more than 250 amps for 3 seconds or less, or if you aren't waiting 4 minutes between cranks. Crank time varies with the amount of current drawn. If cranking draws more than 250 amps, crank time may be less than 3 seconds. Wait 4 minutes before the next crank.
What to do if my DieHard 200.71240 Battery Charger makes a loud buzz or hum?
A loud buzz is usually caused by transformer laminations vibrating, while a hum can be due to a shorted diode. You can continue charging, as the buzz is not abnormal. However, consider having the charger tested by a qualified service dealer.
