I was able to figure out the problem today.
First I took the battery to the autoparts store to have it checked (easy since it’s right down the street)
Then I spent some time examining the wires and all the grounds looked good.
Finally I removed the nut from the lug on the post of the starter relay; I have several cables attached to it and I realized that the heat shrink from other cables got in between the starter cable and the other cables on both sides! I reattached it making sure there was good connection, turned the key, and everything worked. Thanks all for your help!
