I’M ALL CHARGED UP, UNTIL I’M NOT!

RZR PRO-R CHARGING PROBLEMS

A DIRT WHEELS FAN WRITES: I have a 2023 Polaris RZR Pro-R that I waited all winter and spring for. Well now that I have it, when the battery stays charged, it runs great! However, the battery doesn’t seem to stay charged all the time. I have no extra lights or a high-power sound system, but I can be riding along and the dash just winks out and the engine stops. The battery is so low the ignition can’t fire the plugs. I had my buddy jump start me and use his Ranger to charge my battery and then I was able to ride the rest of the weekend. Boss, I replaced the battery thinking it was bad. I also had my dealer check the charging system, and it was charging. If the battery was indeed bad or not charging due to either the battery or charging system being faulty, how could I run all weekend on a recharge without it dying again?

RZR PRO-R CHARGING PROBLEMS

OUR PRO ANSWER: Did your Dealer check for a loose electrical connection between the alternator and the regulator? Or to the battery? Did he do a load test on the battery? Barring a loose wire, I suspect you have a possible heat-sensitive voltage regulator that sometimes charges and sometimes not. If your dealer just started your Zooter cold and did a charging system test, the voltage regulator may not battery charge, you cannot operate all weekend without the battery becoming discharged to the point the Zooter stops. So, this says that your charging system started working correctly for the rest of the weekend. An alternator doesn’t just repair itself. Neither does a battery. But a heat sensitive-voltage regulator, when it cools off, can repair itself and start operating correctly by charging the battery. And if the unit didn’t get hot enough to fail for the rest of the weekend, that answers your question. I would buy a replacement voltage regulator but not from Polaris whose units are known to weak in the heat department. Look at the Quad Logic voltage regulator here: https://www.everythingpolarisrzr.com/polaris-rzr-900-1000-turbo-improved-mosfet-voltage-regulator-by-quad-logic-100-5031-eprzr.html. It should cure your over heating problem.
