P1637 Code
Need Help Diagnosing P1637 Code, Symptoms Are Dead Batt if Not Driven For 5 - 6 Days, Service Engine Soon Everytime Start Up Or Cut off, Volt Meter Shows 11.3 To 13.7 Varies, Code Is For L Terminal On Alternator. I Have Replaced Battery, Also Found Last Time Batt Was Removed, Someone Left A Small Bundle Of Wires Between Battery Bottom And Battery Frame, Not Sure If Wires Are Cut, Have Not Split Open Harness As Of Yet. Is This Small Bundle Of Wires Possibly The L Terminal Wires Going From Alt. To Pcm?, Thanks For Any Assistance. Topkat
