stator winding resistance

Post by Cheese »

Folks,
1982 900SS 2 wire stator resistance from lead to lead is 1.4ohm and from lead to cover is about the same, 1.3-1.4ohm. I'm thinking it has terminal insulation failure? what are my options for repair/replacement? I've called several electric motor repair shops in my area (Schenectady, NY) with no-one wanting the rewind work.
thanks,
Peter

Found what looks to be a good replacement stator at Euro Moto Electrics. Will report back.

Recieved and istalled the new "DUC stator" from Euromotelectrics yesterday. Now charging well. We'll see how it works once a few miles have been covered.

hi peter.
did you out of interest measure the resistance between the 2 wires and wire and chassis?
cheers, phil

Phil,
On the new stator? After mounting in cover and tightening bolts to 70 in/lbs. I measured the wires to chassis with a nine volt meter to be open in megohm range. Will measure wire to wire and report back.

legend, thanks peter. The resistance wire to wire should be about 1 ohm as it is essentially just a long piece of copper wire, but i just wanted to hear that i should have an open to chassis to confirm my problem, which was the same as yours. how you finding the euromotoelec one so far?

Phil,
So far is not very far in this case. That is, the bike is in the process of going back together after a 21 year slumber. So, it works in the garage with the regulator putting out about 15 vdc, and the alternator 130 vac at 3000 rpm. Not sure if the regulator works as well as the alternator at this time. Hope to have the bike sorted enough to prove this, and other repairs by September or so.

Regards,

Peter

hi again. I had a similar problem once and if you are using a digital multimeter , go and get it a new 9 volt battery and you will see the numbers from the bike that you should. I did that recently and my static volts of battery went from fully charged at 14.8 vdc to 12.7 vdc. I then measured the little rectangular battery i removed from the meter and it was only 6.5 , soo the meter was giving me false readings.

sorry , forgot to add, 15vdc is too high, 13.5 is optimal and up to 14 at revs is ok

Interesting. I thought the volt meter function was independant of the battery. Battery used for resistance only? Alt putting out more AC than stock I believe(thought I remembered 75vac stock), so it could be my regulator is over cooking battery, or cannot handle the higher acv produced by the new stator. Thanks for the information and I'll let you know what I find.

Best Regards,
Peter
