I had an errand to run, but got the positive battery terminal unhooked now (rather than the jumper on fuse box), waiting for a half hour to pass, then I'll try to reconnect the terminal and see if the clicking stops. If so, I'll try to start the vehicle again in normal fashion and if it does not cooperate, I'll have the battery checked out.
I figured removing a fuse box power wire would reset it, but ?maybe? the memory for the starter relay didn't power through that fuse box and it never reset by removing the wires I previously removed??? Not sure on the path it travels from where the clicking is coming from but hopefully dropping the battery for a half hour stops the clicking.
As for jump starting the vehicle, I was hesitant to try jumping the vehicle with the continuous clicking. I don't want to cause damage to either vehicle if there is some kind of wiring issues. Out of my comfort zone, but I figured I'd at least give it a try before taking it in.
