Still chasing my phantom voltage leak.

Until I find it is there a downside to disconnecting the battery if I am not going to use the vehicle for a few days?

I typically use the Ex on weekends only.

V-10 gasser.

Will the computer take a few days to "relearn" the settings - especially concerned about gasoline mileage during the "learning" process.

 

From personal experience it seems like my 2000 V10 takes somewhere around a hundred miles or so for things to go back to normal operating. It seems like the idle and overall engine performance relearn rather quickly it seems the transmission takes longer in my opinion.

Have you tried pulling one fuse at a time while monitoring the battery drain? It might be easier to just pull the one fuse once you can nail it down.

EDIT: Just saw this info from my users manual. Cut and paste follows ...

1. With the vehicle at a complete stop, set the parking brake.
2. Put the gearshift in P (Park), turn off all accessories and start the
engine.
3. Run the engine until it reaches normal operating temperature.
4. Allow the engine to idle for at least one minute.
5. Turn the A/C on and allow the engine to idle for at least one minute.
6. With your foot on the brake pedal and with the A/C on, put the
vehicle in D (Drive) and allow the engine to idle for at least one minute.
7. Drive the vehicle to complete the relearning process.
² The vehicle may need to be driven 16 km (10 miles) or more to
relearn the idle and fuel trim strategy.
² If you do not allow the engine to relearn its idle trim, the idle
quality of your vehicle may be adversely affected until the idle
trim is eventually relearned.

 

I'm with Fishing Uncle, just narrow it down to a fuse so that you can at least get an idea of the electrical system that is causing the drain. I'll add if you dont already know that in order to check current draw of your vehicle you'll have to put an Amp Meter inline from your battery. Ie, disconnect your positive lead and connect one lead to the cable and one lead to your battery post to effectively put your meter inline. I dont know the exact numbers but there shouldnt be more than a few hundred mA for your keep alive memories, computer, radio station presets, etc....
