Just wanted to post an update regarding all the electrical issues I was having. The two frayed wires I found, had to have been the cause of the battery drain. It will be 1 week short of 2 months since I repaired the wires. No battery problems to date. The glow plug relay was ready to go and did die over the Christmas holidays, and was replaced. The car start fine. Thanks for all the help everyone.
