A from the readings If the stator fails any of the static tests, it will need to be replaced with an OEM stator for your vehicle's make and model. Headlights and trail lights worked perfectly for about 20 minutes We did a stator ohm test and I read 0. 3) Ohm out all combinations of the 3 yellow wires. I have 0. And on the plug with all yellow wires was supposed to be a 0 reading but I got 00. May 15, 2010 · To my knowledge, a 180W stator is a 3-phase, 3-wire unit and would require a 3-phase rectifier. All 3 have one common connection,the other ends exit the engine in the 3 yellow wires. There should NOT be any reading at all, no circuits to ground. test 'continuity' between BLUE and ground (BEEPS with a reading of 1. The test should show resistance within a certain range (check the service manual). Then test between each stator wire and ground, there should be no connection at all. 2-wire stator, the Green/Yellow is always connected to the other end of all three pairs; Jun 5, 2012 · You should get continuity between any pair of the 3 yellow wires. Screwdrivers: For accessing the stator. Set your DVOM on AC volts and probe 2 of the 3 wires with engine running at idle. If there is a reading, the stator coils and/or the wiring from the coils is grounded and needs to be replaced or repaired. The reading there should be very close to each other, no matter which two of the three wires tested. Mar 15, 2006 · If either lead has continuity to ground, the stator should be replaced. Regular testing helps identify issues early, ensuring longevity and reliability. BRAND NEW - Charging Magneto Stator. I went through 3 stators and finally just asked for my money back. My banshee would run, and the lights worked fine but on the top end it would just run crappy. Jan 4, 2025 · Testing the Stator's Resistance. Dec 23, 2011 · Stator voltage test is with stator wires disconnected, and engine at 4000 RPM. the White/Green (Light Green earlier) is always connected to one end of all three pairs;. Derry. Jun 27, 2016 · Technically there are 3 possible tests you can do on a stator. 555 swapping leads still testing the + input wire the readings at each stator input wires was 1. Start by setting your multimeter to the continuity test setting. 5 ohms range. In a three-phase stator test, connect the probe with 2 phases and get three readings with two different wires every time. C subtract the reading in 1. The winding "LEGS" are the 3 white wires. ohm meter test between each pair of wires(3 measurements) Ohm test to the stator mount or ground. 4 SBT Code# 14-205A OEM # 21003-3729 green to blue 396 - 594 ohm Wire 1 Wire 2 Kawasaki Spec. 060-0. 7 on B/C and 00. 1996 John Deere 455 Then it should have a stator test in it 1996 John Deere 455 OG638491 Beginning to chase down a sluggish charging system. 9 on A/B and 00. 01 The VOLTAGE test on the 3 yellow wires were 41. useful for understanding and troubleshooting the charging system on these classic Suzuki GS motorcycles. my reading 12. If the 3 winding read the same and less than 1 ohm, my guess is the stator is ok as long as none of the windings are not shorted to ground or if you had intermittent problems. Start the bike. Mar 12, 2023 · Or even better, re-pin the 3 stator wires in the VR plug and test again. 20v . 8 to 1. With these two tests you can quickly check the stationary health Jan 25, 2023 · For clarity, all 2-wire or 3-wire Lucas single-phase stators, the six stator coils are connected together in three series pairs:-. 130 14*" (*I cant remember the very last digit, but I think its '2', and since it is mounted on the bike at the moment I cant confirm. 4 after with key off. Book specs . 2 ohms. Make sure you're using the connector that goes to the stator and make sure your meter works. Then, touch one probe to a stator wire and Nov 10, 2023 · Testing a 4-wire stator is similar to testing a 3-wire stator. 3 ohm yellow to black 21. Disconnect the yellow leads to the rectifier. It is the three pronged white plug with three yellow wires. To test a stator, you use a multimeter to either run a static test on the resistance of the wires or a dynamic test on the AC voltage reading from the wires. It worked fine. 05 No load stator test: Bike cold (running for 30 seconds or so), highbeam on, 5000rpm With my voltmeter set as pictured below, I was getting stupidly low readings like 04. Tested passive ohms from stator yellow wires got . ) I like the idea of soldering in the blue wire in to the new stator. Feb 17, 2016 · For those trying to test to see if the Polaris regulator is OK, a initial crude test would be to use a ohmeter on the 3 phase input, A-B,B-C,C-A all should be in excess of 1 million ohms. fvwcieuitntdkcqhtgtlywflgnknlcrkvucxvrrvplgiherkfpqxfioijmaifhtuwjsesauyzsvdpbe
