"check charge sys"
Started getting this message. I'm assuming my alternator is on it's way out. I checked voltage when the car was running and it wasn't much over 12V. The alternator is making some power though because I can disconnect the battery and it will still run. Just wondering if you guys know of anything else I should check before throwing a new alternator on there.

I bought my alternator used. (once again used parts biting me in the ass) Seller said it had ~40k miles on it but it was probably 140k. I had the parts store in town order me in a replacement unit. Going to drop by after work and have them test my battery. I think it is fine but just to rule it out. If the battery is fine I will probably just throw in a new alternator before I drive to an autocross event this weekend 2 hours away.

That is one of the worse things you can subject a computer controlled car to. Since the 80's you never try to run a car with the battery disconnected. Some Chrysler alternators will run into the 60 volt range without the battery.

Nah I meant my ECU didn't explode. I have a spare if it does. Plus I knew the voltage wasn't much over 12 before I disconnected battery briefly. Personally I think it is a shitty design if their aren't fail-safes for situations where the battery could become disconnected.
