We didn't know you were having trouble. At least you brought an old thread back...a third time!

Quote from: BluebellylintI did the Check Kerry linked to above and came out with ~5.5 M ohms between Y1, Y2, Y3 and. then I got 9.78 between R and B/W. are those common failure values? I would think the resistance would go down rather than up if the RR is faulty...

Is that 9.78 ohms or M ohms? If ohms, that does seem low vs the 40 listed on the chart.

In your test, the "Y" measurements are essentially infinity (assuming you are checking the RR side and not the generator side).

I justed checked a couple I have around here (allegedly good) with a digital meter. I think the Haynes uses an analog (needle type) with adjustable scales. That type is probably better for this kind of test.

B/W to Red  = 25 Meg or 4 Meg depending on polarity

Y (all)  = 14 Meg

Now it makes me wonder about my "spares."   These values are way different on the B/W to Red than the Haynes. Again I think it is due to the difference between old school and digital meters.

lol Yea I didnt want to start a new one, this one has so much good info.

Im not really even having much trouble. The lights just get dim at low RPMs and I thought I would check just so I wouldn't get stuck somewhere with lights and fuses blown.

I did mean to type 9.78 M ohms which is way more than the 40 ohms it should be, also the "Y" measurements are much larger than the 6 ohms they should be. could the Haynes manual have a typo or is my RR screwed. But I guess if your RR is getting really high readings also maybe its OK. :dunno:
Thanks for the response
