Did you say that when you turned the key on your old solenoid you just get a click each time? I would suggest a starter assist relay if that is the case. There is an article in the technical exchange section about them. Also, in my signature line, there is a link to a youtube video I made for this very issue. Explains a lot and will tell you how to test with a meter. And, if you have a Harbor Freight nearby, you can walk out with their entry level one (of which I have 2 or 3) for about $6 or less. Sometimes free when they have a special going on.
