OK, I am trying to test my regulator/rectifier but I am having trouble identifiying it. From what I have been told I have a water cooled rectifier. I found what I think is the right part under the power pack. Directly under the power pack is a kind of rubber/gel barrieer and coming out of this are Yellow, Yellow Gray, Gray, Purple wires together and a red off by itself.<br /><br />The reason I ask, is that the post I read about testing the rectifier does not mention the gray or purple wires. Do I have the right part? Will the tests still work?
