What to do if my DieHard 28.71328 has a short or no start cycle when cranking engine?
If your DieHard Battery Charger experiences a short or no start cycle when cranking the engine, several factors could be at play. First, ensure there is power at the receptacle by checking the fuse or circuit breaker. A loose AC or extension cord can also cause this, so verify they are properly connected. Also, check the clamps are firmly connected to both the battery and the frame. Allow for a 3-minute rest period between cranking attempts. If the battery is severely discharged, using the 40/15A Boost setting for a short time might help. Note that crank time varies with the current drawn; if it exceeds the engine start rate, crank time may be less than 5 seconds. Finally, the thermal protector might have tripped; ensure the charger vents are not blocked, wait, and then try again.
Why won't my DieHard 28.71328 Battery Charger turn on when properly connected?
If your DieHard Battery Charger doesn't turn on even when properly connected, the issue might stem from a dead AC outlet. Check the fuse or circuit breaker. Another potential cause is a poor electrical connection, so inspect the power and extension cords for any loose plugs. Finally, the battery itself could be defective, requiring a check.
