Troubleshooting Common Battery Issues

Even with a brand new battery, you might still encounter some issues with your Road Glide. Let's go over some common problems and how to troubleshoot them. If your bike won't start, the first thing to check is the battery voltage. Use a voltmeter to measure the voltage across the battery terminals. A fully charged battery should read around 12.6 volts. If the voltage is significantly lower, the battery might be dead or damaged. If the battery is dead, try charging it with a battery charger. If it won't hold a charge, it's probably time to replace it. Another common issue is a slow or weak start. This could be caused by a corroded battery terminal. Clean the terminals with a wire brush or battery terminal cleaner to ensure a good connection. If your bike starts but then dies shortly after, it could be a problem with the charging system. Check the stator and regulator/rectifier to make sure they're working properly. A faulty charging system can drain the battery and prevent it from recharging. Sometimes, a parasitic draw can drain the battery even when the bike is turned off. This could be caused by a faulty accessory or a wiring problem. To find the parasitic draw, use a multimeter to measure the current draw with the ignition off. If the current draw is higher than normal, start disconnecting accessories one by one until you find the culprit. By troubleshooting these common battery issues, you can keep your Road Glide running smoothly and avoid costly repairs. These are the most common issues that happen with battery problems.

Maintaining Your Road Glide's Battery for Longevity
