Ok now I am puzzled. I got the replacement alternator in and when I start up the volt meter shows about 11 to 11.5 volts. Shouldn't I be reading 14 or so?
Could it be that the PO hooked the guage in such a manner that it is only reading 11 when everything is ok?


Do you have a handheld volt meter you could check voltage at the battery (or at the center terminal of the isolator)? This would tell you whether the battery is getting charged. It is possible there is a voltage drop somewhere that the installed meter is reading. Also possible that the sense or exciter wire is not wired properly causing alternator to not start charging.
