I had a problem like this on a 1997 Pontiac Sunfire, and a 2001 Kia Spectra. On the Spectra, you could see the voltage jump up and down, and the battery would eventually die. On the Sunfire, the early warning consisted of the ABS light coming on -- just like in John's case. :) Vitaliy -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
