Check all the battery connections clean, tight, not corroded? how about the battery have it tested too 12.6 volts and load tested.. Alternator NEXT, 13.4-14.8 volts output at the battery terminals when engine is idling. You'll find the problem in there.Bad ground wires are always a problem.. Regards
