That thought enter my mind too but here is what I found today.I went and did some more testing. I used the analog gage last night ( I know better DUH) but today I used the digital. With lights off it drops to 12.2V from ~14.2V with lights on it drops to 11.8V. I did notice the battery reading 11.5V before start up with the key on. So I guess it rules the ground out. Seems a little low on the battery to start and I am leaning more towards the belt/ alternator as the cause.

Start with the basics!!!! A battery reading of 11.5 volts on a vehicle that has recently been driven is bad...

I would first start with the battery connections...make sure they are clean & tight......I see more batteries etc being replaced because of bad connections than bad batteries
...not sure how you ruled the ground out???

Then test the battery and alternator..

My point is fix the problem you have before you start the car, i.e. the 11.5 volt battery, then worry about the 5000 rpm problem if it is still there..

Good luck..
