I had it hooked up incorrectly for a second(the car goes crazy when you do this...it continuously honks the horn, turns the wipers on, etc). Once I realized what I had done, I hooked it up correctly and it says Charging System Fault. I've checked the fuses underneath the hood and in the floorboard and the only ones that I saw blown were the radio/hud fuse and the HVAC blower fuse.

Does anyone have any suggestions on where I would need to look next?

Thanks,

Read through all of the posts, I'm not running new plugs, my horn works, connections are tight at battery (yellow top). So recently I’ve had some starting issues where I go to start the car normally and it just clicks once and everything shuts off, but I put it in gear and it will start, I had never had to put it in gear to start it, I usually start in neutral. And that issue is intermittent. Now my additional BS is that I’ve been getting an intermittent “Service Charging System” fault, and after reading the post and learning some basics I started paying attention to my batt meter and noticed that it was reading at 11, but it will go back and forth between about 13.5 and 11. When it was reading at only 11 I disconnected my positive battery terminal and the car shut off as I had expected it to do, leading me to believe it was an alternator problem. Well later when I saw it go from 11 to 13.5 I disconnected it again and this time it didn’t shut off leaving me with many questions!! This is my first Vette and have very little automotive knowledge, any help will be very greatly appreciated. If you decide to help me and suggest something to check please be specific as to where it is located as I will most likely not know where to look (to give you an idea of my lack of knowledge I think the starter is under the motor, but I’m not sure).
Thanks,
Chris

You might also check the ground wire from the alternator and make sure its connection is tight. If it is loose or corroded, you would most certainly have an intermittent charging problem. Hope this info helps.
