My alternator bracket broke a bolt and I removed the alternator to replace the bolt. After I replaced teh bolt I reinstalled teh alternator and connected teh bettery, but the battery sparked when I connected the + cable. It turns out that I had bent the large charge wire against the body of the alternator. I bent it back and started up fine. Hre is the problem I have now, no charge. I thought I fried the alternator so I replaced it with another one I had on the shelf and still no charge. I cant find any burnt fuses or wires. I am wondering about the two wires that plug into the back of the alternator. I think one should have 12v on it when the ignition is on correct? or am I Wrong? What do the two wires do, and how I make sure they are doing what ever it is they are supposed to be doing?

One has +12V from the ignition switch and the other connects to the charge indicator lamp.
Go back and check your main fuses - the ones under the dash - if they are all intact, verify that you have +12V on the alternator output lead (that same large charge wire) with the engine OFF.

Teh large wire wont read 12 volts because the battery is so low from not being charged. on the lillte wires should the on from the innition have 12v ony when the ignitoin is on?
-
What voltage are you measuring from the battery? The lowest voltage you should be seeing there is perhaps 11 volts, anything less is pointing to more than just a flat battery - in any case the idea is to make sure that there is a "solid" connection between the battery positive and the alternator output connection.

You may have blown the fusible link.
That is the thick wire that goes to the battery from the alternator with the disconnect on it. The outer cover may not appear to be damaged but the inner conductor may be open.
Check this wire for continuity between the alternator and the battery. If it is "Open" (zero volts when connected only to the battery or infinite resistance when both ends are disconnected) you found the problem.
I hope that this helps!

Thats what I was thinking but my ohm meter died and I ahve to go to harborfreight to get another today. I will let you know what happens. Does anyone know what the amp rating is for the fuseable link. I think if that is the problem in might just put in a equal amp rated inline fuse.

I tuned out that the connector bet the batt and the alt had burned out so I cut it out and installed a 40amp inline fuse and it woks fine now. Thanks for the help.

You might want to use a higher rated fuse - you need a fuse that at least matches the rated capacity of your alternator.
