Why does my ATV battery not charge when I leave it disconnected?
If the battery does not discharge when left disconnected, the issue is likely not the battery itself. If so, it’s more likely something on the ATV that is causing it to drain or causing it not to charge as it is supposed to.
What causes a battery light to come on after an alternator is installed?
The most common is, again, a loose connection either with the control plug (aka “relay” plug-in), charging line connection, or the ground. The other is a blown fuse or defective connector or relay, which could have been broken or shorted when the alternator was installed or on the first start-up after its installation.
What happens when you turn the key on an ATV?
When you turn the key, you get no reaction what so ever. Except maybe a clicking sound from the starter. This behavior is very common when you have an ATV battery that keeps going dead. But depending on what is causing your battery drainage, your bike may behave differently. It can lose all of its power in just a matter of hours.
How can I tell if my ATV battery is bad?
A better way to test if your battery is bad is by performing a so-called load test. Ideally, you would want a load-tester to perform this test, but you can also perform it if you have a multimeter with a min/max function. This will not give accurate results but it should give you a decent clue.
Why is the battery light still on after a new alternator?

What happens when a battery goes bad on an ATV?
No battery lasts forever, and at some point, all batteries will stop working. If you take proper care of the battery, it should last for many years, but if you misuse it, you can ruin it in months or even days. If you were not able to charge the battery above 12.4V, there is a good chance the battery has gone bad from misuse or just from being old.

What should the voltage be to charge an ATV battery?
If the battery is healthy, you should be able to charge it to hold at least 12.4V (about 75% charged). If you can’t reach 12.4V, the battery is not taking charge properly. Then let the battery sit for a day or two and read the voltage once more.
What should I do if my ATV battery keeps draining?
You do not want any debris falling into the ports as this may reduce the capacity or even damage the battery. After cleaning and drying the top of the battery, you can use a screwdriver to pry open the covers or unscrew them, depending on what type of covers you have. Use a flashlight to inspect each individual cell.

What should voltage be on Yamaha XV535 battery?
So once you have a fully charged replacement battery** installed (and likely you need a ignitor too, ouch!) start the bike and measure the voltage at the battery terminals. You should see about 14.5 volts. Less than 14.0 -the regulator or rectifier is defective. More than 14.9- the regulator is faulty and will eventually damage your battery..
