I have A 9o' Fleetwood.The battery seems to drain down if not driven at least once every three days(if driven daily battery is fine).Also the factory alarm seems to set itself off on the 2nd day or so.I don't know if the problems are related or not.I have taken the car to some local repair shops and after spot checking some things, even they are clueless to what could be draining the battery down.I really don't want to go to the dealership and pay thru the nose to fix the problem but it's beginning to look inevitable.

Any suggestions are greatly appreciated.

Maybe the battery is just getting old? It might not be able to withstand even the parasitic draw of keep alive circuits. That low voltage might be causing the alarm to go off though. Sometimes transistors don't know what to do in such cases and start to think for themselves.

Yes,I had hoped it was A bad battery(I replaced it with A new one) The alarm problems may be related to the draining of the battery ,because the alarm starts acting funny when the battery is drained down.I just can't seem to locate what is draining the battery down at such A low rate.
As A rule the car will start unless 4 days or more go by between starts.I hope it is something simple.

I am puzzled.
