ELK M1 Gold Problem

[dsabot]

I've had an M1 Gold for several years.  A few days ago I got a low battery warning on the panel.  I was going out of town and not able to change the battery.  When I got back the keypads were all dead and the main unit just had a power light on, no flashing leds at all.
 
I changed the battery and was still not able to get the keypads to work.
 
When I switch the unit on, I don't hear the normal relay clicks, just a power on led on the panel and that is it.
 
Any ideas?

Power down the system. disconnect the backup battery/batteries and power it back up. then use a volt meter to check the dc voltage on the data bus and the AUX power terminals. I'm thinking that maybe a battery has shorted.
