Just installed a new rectifier and I think it is now charging I thought that the tach not working was because the rectifier was not installed put it in and no dice. I hope some one has an idea. Is there a test I can do to check if the battery is really charging all I did was hook up my volt meter and see if it went up and it did but there has to be a more clear cut test than that
