Alright, so a couple days ago, I was washing my '88 FC, and when I was done, I went to start it up and take it for a nice drive. The problem was it wouldn't crank. So I jumped it. It was running, but when I would put any electrical loads on it the volts would drop dramatically, so the next day I bought a new battery. It was running fine for awhile, but later that night it died again and I had the same issues, so I heel-toed it all the way home. So today I buy a new alternator. Still, the same issue. Then I take it down to Shuck's and have them test it. They clean up the positive terminal and it pretty much fixes the problem, but it is still having a problem. I have aftermarket fans on there controlled by and electrical switch. It turns out, that it adds a little too much of an electrical load. So now when I start it I make sure to start the car before switching on the fans. When I drive, the volts will go up to 14, but when i brake hard, it will drop close to 12, and then when I turn on my headlights, it will drop to about 13. Is there anyway to make it so it doesn't drop so much?

 

help, anyone?
