Is your battery a "more than 2 year" battery? Reason I ask, 2 year batteries are just that, if that. Parasitic draw is just that, something that is draining the battery. You will need a volt meter to read battery voltage. Attach it to the battery, and systematically pull fuses till you see the battery voltage stop dropping. That should indicate the source of the voltage drain.

Hey thanks, the battery is 13 months old, it was good when I first got it, but as the year went on, I say the voltage on OBD wiz go up. From 14.6 to 15.6 and then the lazy starting started. What are the fuses i should start with, any common areas that draw more power or are know to be problems. I have read that TB's have electrical glitches. Thank for the help/

key off, doors shut and all electrical loads off.
remove the negative battery cable....connect the amp meter inline with the negative battery post and negative battery cable.....one meter lead to the battery post....the second meter lead to the battery cable. the meter should go down to under 50milliamps in under 20minutes....most go to 10milliamps in 5 minutes. If you have an aftermarket remote start....it will add 30milliamps of draw.
