membership battery drain on 360

Either you have a dead battery or a short somewhere - how old is your battery and/or do you keep it on a trickle charger ?

 

Are your parking lights turned off (switch on centre console and not the one by the steering wheel)?

 

Mine was caused by a malfunctioning windows ECU.

Parasitic drain.

 

As cars get older, the electrolytic capacitors on the various circuit boards degrade and begin to leak.
When my F355 was new to me (2001) it would go 3 weeks and still turn over.
Now (2018) the battery won't last a whole week.

 

Do you have an after market stereo.? They have been known to drain the battery.

Or similar to above, a door micro switch has been found to short and cause a drain. There are several threads on this on the 360/430 forum

I have had a relay installed so the radio only has power when the key is on.

 

Unbolt your negative battery terminal and put a volt/ohmmeter between the terminal and the battery post. If you read 12.6 volts, then switch to current to see what the drain is. Anything more than ~ 100 mA will drain your battery.
If you are > 100 mA, unplug all your fuses (drain should go to 0), plug them in one by one until you find the culprit. If is stays at > 100 mA with all fuses unplugged, then the drain is on a non-fused circuit (e.g. lights)
