Thats a good idea but the battery only holds up the memory during a power out, if it was in wrong, trouble would crop up when the power dipped or dropped off. That would point you back to your good, clean power source and ground. You are using a battery back up right?
I'll be around tomorrow afternoon (I think) if you need help. Info is in my profile. Bigdog3 in the voicemail forum could also help on this one, you might even cross post it. Just paste the link to here.
