The new battery I put in had over 12 volts.When I tried to start....nothing.Tach went nucking futs.WOW,I turned the head lights on and off with the key in the on posistion,went from zero to crazy.Turned the lights back off and then the tach settled back to zero.Turned the key off then it it moved from 4k to zero then went all the way around till it hit the zero pin.Backwards.I immediatly did a voltage check...8.45 with the cables on.Took both cables off 11.89.Would a bad starter cause this?Its 10 years old and over 100k

When I left a car (Plus from Hell) at my preferred shop for long term a/c work, the battery ran down over time...it was there a month or so. They use a small power pack to start dead-battery cars, and when I used it to crank this one, the tach jumped to about 4 or 5 K rpm the instant I turned the key. By the time I let go, it was all the way around to the high side. It stayed there, and was unusable until it was reset. The car started ok, but it had no speedo and now no tach. That's an interesting experience...driving a SHO with NO speed indication. I had heard about that tach thing happening before, and it definitely was the cause for me....low cranking amperage. If your battery only has 8 volts, it is definitely discharged. Charge it overnight, like Paul 
said. If it still won't crank the car at the speed you are used to hearing, get a new one. Apparent cranking speed is the first indication of a dying battery, at least for me. If the cranking speed starts slower than normal then speeds up, you are about to lose the battery. It's happened twice, on Lowrider, and also on one of the Mustangs...in that case it wound up stranding my daughter in the middle of nowhere at 2 am.
