I am having this problem this morning. Check battery warning comes on and gauge drops to 0. When I turn it off and put the key to acc it comes up to 9, but as soon as I start it, it drops back to zero. I drove it all the way home yesterday (1 hour). This morning though it didn't make it, I had to buy a battery just to get the thing home.
I have the day off and need to get it fixed, any suggestions? Good ground, corrosion free.
