Can a bad battery cause a motorcycle to run poorly?
In both cases, something in the charging system needs to be fixed. It’s possible for your motorcycle to start and run with a bad battery, but that can create even more problems like causing the bike to run poorly and miss.
Why does my motorcycle battery drop when I turn it over?
If the battery only measures to a maximum of 10.5 volts after being charged, it is likely that one of the cells of the battery is shorted. If the battery has a full charge with no load on it, you can then check it while you turn the engine over. A battery may fully charge, but then drop significantly when under load.
When to know if your motorcycle battery is operable?
If the battery drops below 10.8 volts, it is possible that the battery is no longer operable. Significant engine trouble can also cause the voltage to drop too far if it is making it difficult for the starter to turn the engine over. A good way to tell if this is happening is to check the battery cables for excessive heat.
Can a faulty wire grounds cause a motorcycle to die?
Faulty wire grounds are a very common problem, but can sometimes be difficult to track down. Symptoms of a bad ground can range from a completely dead bike to electrical components working intermittently. Checking all of the grounds on your motorcycle can be done quickly if you know where they all are.

What should I do if my motorcycle battery is draining?
If the stator doesn’t provide enough power, the battery will begin to drain. For troubleshooting, the stator connector that runs to the engine m ust be unplugged. With the connector unplugged, you can test the stator for both resistance and voltage.

Can a stator be replaced on a twin cam Harley Davidson?
In this video, Mike walks us through the process of a full charging system test, along with the removal of a complete charging system on a Twin Cam touring model. He demonstrates the stator replacement with a 50 amp upgrade. This upgrade will keep your battery up to snuff as the demands on the battery and charging system keep growing.
Are there rear running lights on a Harley?
You don’t say anything about year but unless something has changed, rear turn signals on Harley’s have never been running lights unless you add the kit to make them so. Can’t figure it out. Brake light works, rear turns work, but no rear running lights.
