I wanted to update you all on the issue with my 2007 Polaris Scrambler 500 not cranking or starting. Turns out, the problem was actually the battery, even though I initially thought it was fine. I had a mechanic check it, and he explained that while the battery had some power, it wasn’t delivering enough current to turn the engine over properly.

The mechanic said that batteries can sometimes show a decent voltage reading but still be incapable of providing the necessary cranking amps. In my case, the battery voltage was reading okay, but the internal resistance was too high, meaning it couldn’t supply enough power under load to engage the starter motor. He used a load tester to simulate the conditions of starting the engine and found that the battery’s performance dropped significantly.

He explained that this is a common issue with older batteries. Over time, they can lose their ability to hold a charge properly, especially under the stress of starting an engine. Even though it had enough juice to power the lights and other electronics, it just wasn’t up to par for starting the engine.

After replacing the battery with a new one, my Scrambler started right up without any issues. If anyone else is having a similar problem, I’d recommend getting the battery thoroughly tested under load conditions. It might look fine at a glance, but deeper testing can reveal hidden issues. Thanks for all the advice and help!
