Just so I have it right, then...for a one-wire, the wire to the battery would go to the ammeter so as to register charging? If it's a 3-wire, one large wire goes to the stud on the back, and the other two go...?
Also, it wasn't me that posted about the radio and power windows (at least not that I remember...but I get older every day, as the wife reminds me).
Thanks again for helping me out.
