RS125 Posted January 9, 2020 Share Posted January 9, 2020 I got some parts from previous owner. How to test them? Stator and rectifier Link to comment Share on other sites More sharing options...
Member Contributer airwalk Posted January 9, 2020 Member Contributer Share Posted January 9, 2020 Specs & procedures widely available, search w/“google”. However, temperature can cause failure so heat parts to normal max. engine operating condition(approx. 220F)..best done in oven as difficult to control max. achieved w/ heat gun/ hairdryer devices...

Member Contributer Grum Posted January 9, 2020 Member Contributer Share Posted January 9, 2020 The Stator you could run an Ohm meter over it. 1. With your meter on the lowest Ohms range measure the three output leads between each other you should read virtually 0 ohms, evenly between the phases. 2. With your Ohm meter on the highest Ohms range place one probe on any of the three output pins and the other on the iron core of the Stator, your should have no reading = NO shorts to frame. Visually, if it's in good condition it shouldn't have a dark/blackened/burnt section of windings. As for the R/R I only have info for a 6gen to check with an ohm meter. Be best to verify the R/R dynamically, it wouldn't be too hard to fit it to your bike for a quick run and with a volt meter confirm its output voltage at the battery.

RS125 Posted January 12, 2020 Author Share Posted January 12, 2020 works for me. These may just be spares or artwork for the garbage can Thanks I figured Ohm I guess I was lazy and didn't wanna search Lol Link to comment Share on other sites More sharing options...
Member Contributer Captain 80s Posted January 12, 2020 Member Contributer Share Posted January 12, 2020 I wouldn't throw out anything without actually trying it, unless it was a stator that tested bad AND was toasty black. Working at a dealer for 12 years, I have seen good units test bad, and bad units test good. Link to comment Share on other sites More sharing options...
