thamk you very much for breaking down some of this wireing for me. i have been triing to follow the wiring diagrams in my manual, but they are soo busy, it makes it hard. My starter relay is square with the terminals on the bottom of it. I will check what you have suggested and try to follow all these wires and get back to you. electrical wiring is still one of my weak pionts. the last time this happened to me, i relaced my battery and my starter/soleniod (which does have the diff. size terminals) and the problem was an elec. connection from the coil to the distributor. of course I have check those connections over and over already this time.
i even get the click when I use my jumper to try and start the engine. I really don't believe that the batteery is low. I leave it on a 2 amp trickle charge that automatically goes on and off to the batteries needs. the charge constantly tells me it is fully charged. but, i may have to look into this as a problem as well anyway.
the solenoid is really what I am thinking that my problem is. last time i took my starter up to auto zone to have it checked they told me that it was bad. $130 later, someone else tested it in my garage and said it was still good. so I don't really trust them to take it up there again.
thank you,
