Stator story - No spark

[mrflorida]

My 1995 120 Force was not getting any spark so I started troubleshooting. After talking to a local parts guy he said it might be the stator. Tested it the resistance and it was open. Ran some voltage across just to make sure and still nothing. (it should have low resistance only 600 ohms) ok clearly bad. Need to make sure cause the part was 180 bucks. (new..cheaper than this site!;-) ) The parts guy also said if it is a black stator they are more likely to fail. The reason is they have square 90 degree corners that stress the wire and thus more likely to fail. The new one I put in is Red. This one has rounded corners for better fault tolerance. Hope this helps someone..

Re: Stator story - No spark

The metal frame of the stator consists of several layers of stamped steel. The bobbins for the coils are part of the frame. In stamping, the top edge is somewhat rounded and the bottom edge is usually sharp. The sharp edge cuts into the thin coating on the copper wire wound around the bobbins and eventually cuts the wire itself. The red stator frames have those sharp edges rounded-off and the failure rate is a tiny fraction of the black ones.
