Default Re: Why does this wire Spark?

The yellow wire with black tracer is live . If the yellow wire with black tracer isn't connected to the alternator it will spark any time that it is touched to anything that it can ground on including the post on the alternator . It may be hard to understand how the alternator can charge back through a live wire . Thats just the waty that it works .
