high battery voltage I just finished trying to do a motor mount swap, but couldn't get the bolts off so I just packed up and left put everything back together and now I'm getting off the chart voltage on the gauge. I assume the gauge is working as it doesn't immediatly jump to 18 volts. If I touch the gas the air bag light comes on and so does the check gauges. Can someone help me on why my battery would read such high voltage. I of course removed the alternator, but what could cause the high voltage? I don't see what could cause it.

As far as I know,the v-reg.(part of your alternator) is the only thing that can allow the voltage to get that high(if its' bad). I changed a alt/reg on a friend's car because it was constantly 17 to 18v.
You might have a reg that is intermittently going bad.
