Looking forward to any ideas
thanks

This is a shot in the dark, but if you have an MSD ignition and if the main feed wire (heavy gage red wire) is not fed through a relay or other switched source. The MSD will drain the battery in about a week even if the control wire from the ignition switch is off. I use a battery disconnect switch because of this and have used the same Optima battery now for 5 years with no problems even after letting it sit for 6 months with out charging.
