How To Test The Charging System on a Motorcycle, ATV, & UTV

[@paulmessikommer4027]

very well made, thank you very much! loved the last test with the load allowing us to see the RR at work providing more amps..... highly likely what's not happening on my motorcycle. cheers from CH

[@CaseyGordon]

This was incredibly helpful and insightful, thank you for putting this together!

[@theone2be33]

I like the part about checking for parasitic draw. Learned something new

[@shawnbebout]

Starting to troubleshoot a charging problem on my atv. Extremely grateful for your videos.

[@bradenhein8397]

what was the issue? experiencing similar thing on my atv

[@shawnbebout]

@@bradenhein8397wouldn't charge battery. Regulator checked good, the stator ohmed a little low, but ac output from the stator wouldn't increase with increased rpms. i just pulled it apart today and the stator was starting to burn up.

This was an awesome explanation. This guy is so good a moron like me understands thanks pal

What clamp meter are you using? I don’t wanna buy the wrong one.

[@markfrasson5545]

Should my battery voltage fluctuate between 12-14v while running ?

[@kikemotors6138]

Mine goes down to 0.00 and does not start starter solenoid just buzzes it's on a 2005 Polaris predator 500

[@heathrowism]

Brilliant 😉

[@marcgariepy]

great vid

[@mikemyers193]

I have an '04 Yamaha Bear Tracker. The battery got super hot to the touch and I could smell sulphur. I tested the rectifier and got a pretty consistent 630/OL. Is that too high? The battery itself (once cooled, next day) was at 12.83v and when running seemed to be charging at 14.3v. I have not had any charging/starting issues beforehand. I haven't run it again to see if it got hot. The battery is only 2 years old but could it be the culprit? Anyone have any ideas? Thanks. Great video BTW

[@rhouser1280]

Just curious if you ever resolved the issue? Also what were you measuring that was 630? Volts AC? Ohms? Diode check?

[@lvl48soldier]

So do normal atv charging systems not charge at idle?

[@qtguidrey]

I have 12v but no lights come on and it will not turn over when trying to start. Please help. 2015 rzr 900xc with 1260 miles

[@timothyjohnston187]

I can start my Polaris up and the voltage in the dash says 10 and slowly decreases until the engine stops the battery is old and not maintained but it should still try to charge at 14 and a half volts but doesn't

[@blue03r6]

I had a ranger what started out overcharging. I replaced the regulator then it was working fine except every few mins it would drop to 0v and go back to 14.5 again. these polaris vehicles the RZR and ranger have seriously flawed wiring systems. they always come in our shop with massive wiring issues that are a pain to figure out. I have the polaris dealer software and connector for the laptop. a guy brought one to us that had 18 trouble codes but the dash wouldn't show that it had them stored. he brought it in because of the EPS system trouble light comes on. I gave up on that one. polaris couldn't figure it out either. I'm sure it needed a new wiring harness but the guy didn't want to pay for it. it's about a 20hr job at $80/hr plus the $1000 for the harness.

[@ryanrutten7778]

Basic stuff. Nothing on regulator rectifier. Searched your videos. Can't find. You got link?

[@rmatvmc]

Glad you found it, *Ryan.*

[@theone2be33]

Use your multimeter on Diode setting.

[@mrChienchaud]

Ok well i have a question, my battery is at 13.1V AND IT IS BRAND NEW. but when i try to start my atv, it dropped at 4V and and it's turning too slow to start... When i boost my battery everything is starting fine. I changed my starter cause i thought it was bad but it changed nothing... Someone can help me please?

[@davidwheeler2405]

We're is the rectifier regulator location on a intimidatetor side bye side

[@rmatvmc]

From what I can find, it looks like it may be located towards the rear of the frame close to the battery. However, we are not familiar with that machine so checking with your owners manual would be the best bet.

[@keithbennett1359]

I was watching your video on charging test and noticed that your charge at idle was 14+ volts , I am currently working on a 2015 Polaris 570 sportsman which had the regulator connector burnt very badly . What brought the bike to me for service was a code168/3 system over voltage. The first volt test showed 15.5V . I then cut the connector out and reconnected the stator wires to retest and the voltage was 14.5 approx. Specs for this bike state 12.5-13 v at idle so after checking everything possible including the draw on the battery and finding nothing wrong I replaced the regulator and still have 14.5 v at idle , this is considered an over charge which will in time cook the battery and possibly the ECM although so far the code 168/3 has not come back. What are the chances of the new regulator being faulty?? I was just wondering about your thoughts after seeing your idle volts at 14.5 at idle and no mention of an over charge

[@grizz6370]

My 570 runs at 14.4 all the time

[@keithbennett1359]

@@grizz6370 I spoke with the people at RMstator and they said that Polaris has ongoing issues with their charging systems , RMstator designed a dual stator/regulator set up which reduces the heat of the original system and is a direct replacement but it is not cheap

[@grizz6370]

@@keithbennett1359 good to know and thanks for the info. Greatly appreciated!

[@SWebb-tg1ki]

Once u identify the source of the parasitic draw how do u fix it?

[@rmatvmc]

It will depend on what you found. Say your problem was a faulty regulator/rectifier, you would check all the connections and test with a multimeter and replace it if it's not working properly.

[@ernestoluzan]

It’s almost always gonna be something that’s been added aftermarket. In all my years as a pro technician, this has been true. Next would be a short to ground in any circuit with common B+. Lastly the largest culprit for early battery death, stator/rectifier/voltage regulator death is high voltage drops on power or ground side of main cables.

[@steveschumacher9873]

I have a 2012 Kawasaki Terex for mice we was riding today and my rectifier started smoking

[@stephenaddair]

I have changed the rectifier and stator on my 500 Rubicon and it still doesn't charge, does anyone know why?

[@willyck948]

14 minutes into video I don't think it's a good idea to load 100 amps on charging system but in reality no different then running a winch👍

[@JT_70]

5,000 rpm? Most ATVs don’t have a tach so how does one know the engine speed? I’m sure that I have never rev’d mine anywhere near that high. It’s a utility quad.
