I posted a problem earlier, with the post "hot starting problems". I followed the advice from the last reply posts to put in a new rectifier & wire. I'm awaiting "back-ordered" parts. Could be several weeks, and now I'm losing out on the great fall weather to be riding in. Here's my question: I looked at the "wire" to be replaced, checked & cleaned the ends of the connections. Seems good. What exactly does the rectifier do? It just seems like a heat-sink or something that sits atop of a computer CPU. Is there actually electrical components down inside the honeycomb that might be bad? Or is this thing just a hunk of metal to help dissapate the heat from starter wiring? In other words, can somebody "rectify" my rectifier rectification question?
