I have a 1985 Capri with a 302 and I just got everything back together. I'm having a problem that I may already know the answer to. I have an electric fuel pump, electric water pump, and electric fan. I have an issue where if I run all of them for more than 10 minutes or so, it stops charging. However, if I let it sit for 15-20 minutes, it's ok again. It's done this more than once. So is it just a problem where I'm drawing more current than it can support? I have the factory pullies on.

If I decide to go with something that is 100AMP or higher, what is the easiest way to go, and does anyone have a link for instructions so I can look before I buy.

What products can you recommend? Powermaster?
 
If you are running a stock alternator then yes it can't handle the load. I ordered a 130 amp 6G alt off of ebay. It was $100 shipped and it came with the regulator plug and instructions. I went to the junkyard and got a 175 amp fuse with about 18" of battery cable attached to it from an F150. Then I picked up 10 feet of 4 gauge cable and eyelets for the positive wire. I think I only used like 7 1/2 feet. It is also recommended that you get a better block to chassis ground. I got a 30" battery cable with eyelets on each end for that.
 
I run a pa performance 3g alt and they make one for you. They come with a lifetime warranty and are a qwqaulity alt. The instructions are really easy and step by step and you can get the upgraded power wire/fuse kit. They have great cutomer service also. mine went right in just had to grind a small spot on the bracket no biggie but gald to have my stocker gone.
