Help! I screwed something up. . . .
I pulled the cover off the car for the first time in about a month. The battery was so dead, it almost seemed like that was a connection issue as the guages did not respond to turning the key, the interior light did not come on etc. I wanted to make sure that it was the battery before I pushed it out to jump it, so I got the portable battery jumper box to hook it up and see if the lights would come on etc. I did not even pay any attention to what I was doing (what a bonehead!) and crossed the connections. After about 5 seconds, I realized what I had done when I smelled burning wires and noticed the smoke coming out of the cowl area of the hood. I quickly unplugged the battery cables and after realizing what I did, I checked out the car. Everything seemed fine and then I jumped it with the car. I got the car running, but now my amp guage is going crazy. It runs up to 40 as the RPM's increase and is very much impacted by brake lights, headlights, etc. (goes to 0 or below). I am assuming I fried the voltage regulator in the alternator.
Any ideas?
Can I drive the car to Autozone tomorrow to get them to check the alternator or will it fry the battery? Should I just go and get a new alternator and replace it?

It probably is the regulator. There is a module that blows in it.
The part is only about $15.

This is just a basic Delco Remy alternator. Do all of these have a replaceable regulator or is the whole alternator toast? Is the regulator inside the alternator?
I have never replaced a regulator and I do not want to be taken by one of those dudes at the auto parts store.
Thanks

Just go in and buy a voltage regulator. $15.00 max. It is extremely easy to install. I have put 2 of them in, and they do come with instructions. FWIW they are in the back of the alternator, and it does require taking the cover off of the alternator. Do not put grease on the bearing surface in the rear of the alternator.

My car is a '68 model and has the external regulator that is mounted on the inner fender next to the alternator. I am assuming that this does not change the diagnosis?
I have to assume that the alternator is charging given the high amp reading on the gauge.
Do you just think it is the regulator?
