I only noticed this yesterday with the car sitting, I saw 12.5V at the battery and 11.8V while logging in link. I believe that the same drop occurs with the car running but I will confirm in the next day or two and get back. Could this indicate something along the lines of a bad ECU ground? My battery cables are brand new and the connections have been meticulously checked as I had starting issues last year. There was a thread a (really) long time ago (can't remember if it was on here or one of the other DSM sites) about voltage at the ECU, alternator, battery, etc. comparing and discussing them. I'm curious to see what your results are with the car running. I don't have Link in my Laser otherwise I'd test my car out and see what I get. (The Talon is put away right now)

Iirc Ive added an additional 4-5 grounds around the engine bay, and it certainly helped raise my voltage. I also resanded(made sure no paint or rust) all the factory grounds to ensure a solid connection. The alt is grounded by the block, so I always run a ground wire on the pivot bolt to the chassis to ensure a solid ground. Kevin has some good suggestions. This seems to have made small improvements (at least) for a number of people that I've read about doing it, so it's definitely worth a try. Would start with the alternator personally, and go from there. It's definitely one of the more critical items given that your entire electrical system relies on it.
