How to troubleshoot a DieHard Battery Charger that won't turn on?
If your DieHard Battery Charger will not turn on, and no LEDs are lit, the AC outlet might be dead or there could be a poor electrical connection. Check for an open fuse or circuit breaker supplying the AC outlet. Also, inspect the power cord and any extension cords for loose-fitting plugs.
Why don't the battery clips spark on my DieHard 28.71219 Battery Charger when I touch them together?
The DieHard Battery Charger is equipped with an auto-start feature. It won't supply current to the battery clips unless a battery is properly connected. Therefore, the clips will not spark if touched together; this is normal.
What to do if the CHECK BATTERY (red) LED is lit on my DieHard 28.71219?
If the CHECK BATTERY (red) LED is lit on your DieHard Battery Charger, it could be due to reverse connections at the battery or because the battery voltage is too low. Unplug the charger and correct the lead connections. This charger has an automatic start feature. If the battery voltage is under 0.2 Volts, the charger will not detect it and will not start the charging process. Have the battery checked/ replaced. Another possible cause is that the battery is not properly connected to the charger. Ensure that all connections from the battery connector cable to the battery and to the charger are tight.
