Battery dying after using accessories

[Djones]

I have stock headlights and winch on my 2023 can am defender xt max hd10. Installed a new battery Becuase I was getting a “pps fault” on my display. After changing the battery any time I use my accessories my voltage drops and the machine won’t start back up. After about 20 minutes it will start and runs fine until the lights or winch are used.

That's a tough one; I think you need to start with a voltmeter and check the battery voltage after sitting overnight. The voltage should be at 12.6 to 12.8 volts. If the voltage is in the range check the cranking voltage of the battery while the starter is turning the engine over it shouldn't drop below 11 volts even momentarily. Once the engine is running the charging voltage should be 14volts or higher.

If the above voltages are in range you may need to have your new battery load tested as it may not be up to spec.🤔
