    Nice work folks. While going through your steps to do a dynamic stator test my stator performed just as you explained for a three phase stator. AC voltages at example RPM's. The thing that left me stumped was my Shop Manual states that an AC voltage reading should be between 10 and 12 VAC. Not giving any engine speed. At idle it is producing 17 VAC. Increased engine speeds also increased VAC. Should I assume this as a typo and direct my attention towards the rectifier? This is on a 2005 Bombardier Outlander 330 HO 4x4.

    Thank you for this video!! Misdiagnosed my stator as being bad before moving on to testing the regulator/rectifier on my 2016 KTM 500 EXC. Hadn't opened the case up yet and this set of tests confirmed my rectifier/regulator was still good even though I had a bad pin in the plug.

    If only there was a good wiring diagram and specifications from the manufacturer we could actually know what it should read. Lab scope pattern. NO way. they have them but would never share them with the public to help repair their products. Thank you Rocky for all you do for the general public. I find all the instructions you give are very accurate. Electronics is my specialty but without known good specs and patterns it's all guessing!

    this goes for street scooters as well. 150CC and down usually a 1 phase. some 3 phase. I had one go bad on a scooter that showed working correctly until a long drive at night and the volts dropped. was the regulator heating up and maybe a diode or scr going open. great basic test! 6 diodes on 3 phase. getting a service manual for your bike ETC is a big help.

    I’m doing this test on a Linhai 2018 400cc UTV.
    It’s a brand new rectifier. The forward bias test (black lead to positive, testing connector with red lead) resulted in 530 on each connector. Way outside your proposed range of 0.3-0.5. So… what does this mean? I’m testing this because this rectifier gets super hot when in use.

  • @RR-xb7dl
    @RR-xb7dl Рік тому

    Does it matter if all the forward bias readings on the positive side are 0.1 when all the readings on the negative side are 0.45? In other words, should the readings be close to the same for both the positive and negative? This is a Honda regulator.

    Video is little old but hopefully you still check. I have 2007 V Star 1100 and when first started I get 13.8V at battery. After a few minutes running, I only get 12V or less. I checked stator harness and get over 48V when fast idol so I believe stator is fine. Can rectifier work in start up then stop sending charge to battery?

However, when i rode the bike, voltage jumped to 15.7? Previously I found the "OLD" battery overcharged swelled up and blown, tested the old rectifier , at 3000RPM jumped to 19+volts, i replaced the rectifier with the a NEW one and NEW battery..

      Sorry we didn't get back to you sooner. Did you get the problem fixed? What machine is this on, year make and model? I want to look at the wiring diagram. Unplug the reg/rec and check each wire coming out of it to make sure they are all insulated from the body of the reg/rec. I think that is the only test a manual won't show but if you have continuity on any of those to ground then it's bad. I've only seen it where the positive to the reg/rec body is in the K ohms or Mega ohms and drains the battery over night. Have you checked the voltage at the battery with and without the machine running? With it running, rev the engine a up and make sure the voltage doesn't go over 14.7 ish Volts. If it goes above, then the reg/rec is bad. Sounds like you already checked the diodes, so if the other checks are ok then start looking for a short to ground somewhere.

I had thought that the light brown with red trace was positive but when I do this I get no reading between it and the 3 yellows.

      @rmatvmc  Рік тому

      No, a misfire is not a symptom of a bad regular/rectifier. Misfires can be caused by many things but somewhere to start would be with the ignition system (spark plugs, wires, coils, etc.). Some other things to check would be with the jetting if your bike is carbureted or some sort of vacuum or fuel leak.

    Just went through the test on a voltage regulator on a 1998 Honda Foreman 400. Tests went well and the video was very informative. Thank You.
    Im still having troubles with the charging system I THINK!!!!!!! Crank the bike and the fan comes on. That could be the fan contol or oil temp switch. I understand that. My issue is that as you rev/increase the throttle so does the speed of the fan. The fan speed decreases as the the throttle decreases also. Upon increasing the throttle I also see voltage at the batterry increase. I have seen it up to 18.36 volts at the battery and I know this is too high and will damage the battery so I havent ran it long like this.
    I was wondering if anyone had any other advice on this problem.
    Thanks

    • @rmatvmc
      @rmatvmc  4 роки тому

      If you haven't already, get the Reg/Rec replaced and test the battery as well to make sure it is OK. The voltage at the battery should stop rising around 14.7 V no matter what the RPM is. If the voltage goes very much over that (15 or more volts) then the regulator part of the Reg/Rec ins't working properly. That should take care of the fan speed problem too. I hope this helps

    Hi folks. I have a Honda VF750f Interceptor which I am restoring.My issue is this , having got the bike running, after a while I noticed the battery was starting to cook so I did some electrical tests and found that the battery was being charged at 18.5 volts. I did multi meter tests on the alternator and regulator and found the alternator to be fine but the regulator was not. So replacing the regulator and battery solved the problem. the battery is new but I've used a second hand regulator I had, but it works. My problem know is that in running the engine up to temperature to then adjust carb settings I had the seat off of the bike and when I put my hand on the seat rail above the regulator and touched the regulator with my finger and got severely burnt. I now the regulator runs worm but surely not that hot. I noticed that as from standard the regulator is mounted on a stiff plastic board and not on a metal plate which I would have thought would of acted as a heat sink. Should it run this hot , or do you think this is why the previous regulator ended up over charging ? What could you recommend to solves this suspected over heating.
    Many thanks, Mike.

    I know this video has been around for a while but I’m testing the reg Rec on an 02 Ducati monster 750Si.e.
    It has 3 yellow wires so sayings it’s 3 phase. On the other plug it’s got 2 red and 2 green.
    Should the test be run forward and reverse for each red and green wire across the yellows like this video?
    So did the tests off both the + and - sides and they passed. So guessing it’s good.
    My reason for testing is a slow drain on the batt. I have had a swollen batt also. I replaced it. I have to put the bike on a charger if I’m not driving every couple days.
    I tried an amp test for parasitic draw but it must be so low the meter didn’t see it.

    This method is valid only for simple rectifiers. A rectifier/regulator may have extra components in line with the positive output of the bridge rectifier preventing the measurement of half of the diodes.

    My stator 3 phase went bad I've had to cut the wires to the rectifier as they were hardwired does it matter how I connect the new stator as the three wires are the same colour any advice would be muchly appreciated cheers

    Very good; does this only test the RECTIFIER(S) part? Could the unit stil be bad on the regulator section?(of course,if the motor runs,you just slap the voltmeter leads on the batt.terminals to find out)

      sometimes R/r pass all these test but they are still not working. the best way is to borrow from a friends and try it.

    Hey all I got a gsxr 750 the problem I'm having is when the bike is cold starts every single time but when you ride for a bit and gets up to temperature If you stop and got to turn it off again it don't like starting iv changed the battery and starter motor I'm getting 12to 13 volts when off and 14 volts when it's started so power isn't a problem if you let the bike sit for 10 15 min it's starts again it's like something gets hot and don't like it and seems to turn over like a dead battery .anything else I could try thanks

    Where is the regulator/rectifier located on a 150cc scooter exactly? This is my first scooter and it's become abit overbearing when it comes to doing my own repairs. Your help in this matter would be greatly appreciated.

    hello, as you have shown, the regulator looks solid but no energy output, no voltage. The stator is newly clung and rugged, the outputs have ~ 50V. Is there another test method? motorhome Ktm duke 390 2016.

    Hey! Thanks for the video I have done the test on the rectifier and the stator. Both the stator and the rectifier pass the tests. Putting a voltmeter on my battery and getting the rpm up to 5k like stated in your other videos you have posted the battery voltage does not fluctuate at all. I also disconnected the red wire from the starter solenoid and tested the voltage coming from it with the engine running and it was very erratic going anywhere from 12 to 14.5 volts but as soon as I reconnect it back to the starter solenoid it basically flatlines and there is no change in battery voltage. Any help would be greatly appreciated thank you!

    Hi I disconnected my faulty rectifier. My ATV does not want to idle. I've static test everything and it all test good except for the rectifier that boiled my battery. It's a sizuki king quad 450 fuel injection bike. Any advice would be appreciated

    • @rmatvmc
      @rmatvmc  4 роки тому +1

      Your ignition system is a DC CDI meaning the battery is the power source for your spark. The battery needs to be fully charged for the machine to run correctly. I would replace that faulty reg/rec and battery. I would imagine that will take care of your problem, but if not, you definitely need to start there and have the charging system and battery in good condition before going any further.

    Hello rocky mountain, can we also verify a 3 phase rr unit by looking at the pins on the plug/ port in the rrunit. Doesn't 3 pin on the rrunit mean 3 phase charging system. I.e the top 3 pins for the battery positive,negative, don't know what the middle pin do, and the bottom two pin for the alternator. Am i right or is there something u can add to it. Thanks

    Does this and the stator stop it from running or no.. I have a 2001 Yamaha worrior 350 and the dude I got it from said that he got it running then he said the stator started smoking. Then the atv stopped running.. I replaced everything one that atv except the stator and was wondering if the stator could stop it from it running.. even got a brand new battery for it.. and it's trying to start but won't.. need help..

    Hi there, I have a triumph street triple r 2011 and am having problems with keeping the battery charged. I did this test - with the positive probe on the negative connection i was getting a reading in the 500's on all pins, but with the negative probe on the positive connection i was getting a reading in the 130's on all pins (note my diode tester shows readings differently, e.g. as 138 not as 0.138). Does this imply the rectifier is the problem? Thanks.
