Thanks for all the suggestions. Once all the holiday stuff is over, I'll get back to work on it and check some of your suggestions. I did just replace the starter relay. If the amp gauge is bad, does that mean that the key won't engage the starter? Is it normal for that silver thing in the picture to click like that?
The wiring from the firewall to the relay, including the battery cables really leave a lot to be desired. I may go ahead and replace that harness. It could very well be the problem.
Mike, I will definitely check the coil. I have noticed that when I turn the key to 'on', none of the gauge indicators or lights come on. The only thing that works (that i have noticed) is the right passenger marker light. I do have current going into the fuse box, but that is as far as I have gotten, other than this click when hitting the ignition.
Also, when engaging the starter using a screwdriver on the starter relay, the coil got very, very hot.
Thanks for listening.
