another charging problem...

0.62 volts are coming out of the rr. on the brown wire.. the chart says it should be 0.2 or less. anybody have any idea what connections i should check and where they are located? The stator checked out fine and i am hoping the rr is ok also and its just some connection issue. symptoms include intemittant charging when system is cold but nothing when it heats up.

so the yellow wires coming out of the stator should be fused....hmmmm....wouldn't a thermal protection switch be more suitable? its just a thought.....i am sure someone has thought of it already and there is a good reason why it won't work.....

No, I don't believe that they have any fuses on them. Some guys on the forum have tried fusing them. But I think the conclussion was that the fuses served no real purpose.

I agree with NOT adding fuses to the stator wires. Best thing there is to make sure the connections are clean and tight, or to trim back the connections and solder the wires and heat shrink them individually, keeping the three wires separated from each other. Never bundle them together as the heat that they generate can be pretty hot and can exponentially heat the bundled group and cause failure.

Have you gone through the procedure to test your charging system? Here is the link to the electrosport document you should follow: http://www.electrosport.com/technica...ng-diagram.pdf

What chart is that? The brown wire voltage should be above 12V with ignition on and around 14V with engine running.
