Hello my name is MIke,
You stated that the battery post was corroded, which post was it? It seems odd that the accessory shutoff relay would allow the battery to be drawn down to the point of being flat. Was the battery a fully charged unit or did you get a battery that had little or no charge. How far did you drive in those couple of days after you installed the battery?
Let's see if we can find an answer to your problem.
I would have the battery recharged and tested at ORielly's. Its possible the battery could have had a low charge. Also I would double check that the cable and/or the battery terminal is tight and that all the connections or wires are connected and tight.
I believe it a good possibility that the battery was low charged and caused your problem.
If i have answered your question please accept my answer.
If I can help you further please let me know.
Thanks for the update. So when your husband has a chance to recheck the cables and should check the other cable and terminal also to make sure it is corrosion free also. Let me know what happen with the battery and whether there were any wires or connection loose at the battery?
