The battery light was flashing and and volt meter in 2002 Tahoe showing below normal charge. Replaced alternator and now testing with proper voltage but battery light continues to blink. Cleaned and checked connections, seem to be ok. (Idle jumps at time but may be unrelated.) Code reader shows P1637 "L Terminal Circuit". Any suggestions/tech knowledge that may lead to a fix would be greatly appreciated.
