Common Issues and Troubleshooting
When changing the battery on your Harley Davidson Fat Boy, you might encounter a few common issues. Here’s how to address them effectively.
Slow or No Start
If your bike struggles to start or doesn’t start at all after battery replacement, check the connections. Make sure the terminals are tight and free of corrosion. If the battery is new, it might be undercharged; consider charging it fully.
Dim Lights or Electrical Problems
Dim lights can indicate a weak battery connection or a faulty battery. Inspect the battery terminals for any signs of wear or damage. Cleaning the terminals with a wire brush may help. If issues persist, the problem could stem from the wiring or fuses.
