Also try your fusebox for any blown fuses,I had this on an xr2i,wasn't an obvious fuse either but after changing the alternator on my mums drive using only a few basic crap happy shopper tools and a tablelamp in the rain I was mighty pissed off the batt light still glowed,before the days of Internet forums I'm afraid!!!
Checked fuses and one had blown,changed it and the batt light went off!!!!!
