How to troubleshoot a Napa 90-650 that won't turn on?
If your Napa Battery Charger won't turn on even when properly connected, there might be a few reasons. First, check the AC outlet for an open fuse or a tripped circuit breaker.

Why is my Napa 90-650 giving me a short start cycle?
If you experience a short or no start cycle when cranking the engine with your Napa Battery Charger, consider these potential causes: 1. Check the AC outlet's fuse or circuit breaker. 2. Make sure the power cord and extension cord are firmly connected. 3. Verify the clamps have a good connection to the battery and frame. 4. Allow 3 minutes between cranking attempts. 5. If the battery is severely discharged, use the 40A Boost mode briefly. Also, high current draw can reduce crank time, and overheating can trip the thermal protector. Ensure the charger vents are clear and allow time for it to reset.
