Boxster S 2001 electrics issue causing battery drain

[san rensho]

Disconnect the negative cable to the battery and connect an amp meter between the terminal and cable. The background draw should be around .04. If its higher remove fuses one by one until the draw falls. Thats the circuit thats bad.

If you do it that way you loose you clock setting, etc. My way showing in the PDF (personal data file) I posted you don't loose you clock setting, etc..

Ahhhmazing, I was on my way here to start this very post. I too am experiencing issues. I've been experiencing this issue since I bought the car. But it's not consistent it can be fine for a year but randomly car won't start.... And this will last a week or so... And then the car is fine for a long while. I eventually replaced the typical, starter, Alternator, and a new Bosch AGM battery.

I do know that there have been relay issues. As in sticky relays or burnt out relays. I assume the previous owner had an Issue with a fuse and replaced the fuse for the top/windows with a larger fuse. It burnt out one day rolling down my windows so I replaced it with another not knowing it was extremely high volume what it required. The power wire for that switch melted. I ended up removing the dash and repaired all damages. Later in the year my blower started taking a while to activate. Eventually it stopped working. I found the relay was burnt.

Been thinking maybe fuses are getting sticky and causing issues. I was thinking of replacing all relays with new ones.

But I have to get this under control. I can't risk damaging my new AGM, I do have a 4 year warranty but still. Pushing my car down the street to jump start it before work isn't entertaining.
