1st nova , first problem

[slugger1990]

had my nova GTE replica a month now , and took it a fairly long run on thursday nite , after that my alternator was overcharging my battery + the volt meter on dash was at top of scale , friday nite the battery was literally steaming , saturday i put a another alternator on it from my mates 1.4 sr so i knew i had an ok alternator , changed the battery aswell + all seemed well
going to + coming home from work 2day the volt meter was sitting at normal when revs were at idle but when revs were raised it went to top of scale again , then twice on way home the volt meter dropped to below average while revs were raised then jumped back up
does anyone have any ideas what this could be ?
