Wow this is frustrating,
I have a .25 amp drain I have narrowed down to the ECU-B fuse circuit. Of that .05 is the Car Alarm which means I am losing .2 amps somewhere and Im buggered if I know where. Any thoughts?
Oh and I only use the car maybe once a month so the battery gets hammered every time.

Re: ECU-B Amp drain
Couple common faults worth chasing if were talking about an SW20.
> door harness short.
> bad caps in ECU

Re: ECU-B Amp drain
Yup its an sw20,
I did read somewhere that the B fuse actually had nothing to do with the ECU.
And I have a good battery charger too but I have run the NEW battery down twice now and I don't think its that good for the battery.

Re: ECU-B Amp drain
If your using the car that little, I would probably remove the battery terminal. Mine shows signs of going flat after just one week, but I started and run mine for a half hour every week to stop it going flat.
