The DCC circuit turns out to be a short pin. This short pin feeds the Dome and ECU-B circuits.

the ECU-B circuit seems to have about 49 mA load on it. I will have to go to the component by component

trouble shooting method.

Atleast I am gettting closer I believe.

Battery in the car is new, the mechanics that were looking at the problem actually changed the alternator and 3 different batteries.

Maybe it will be something easy like the electric seat controls.................

The DCC fuse has no amperage rating on it and I cannot find anything in the manual that tells about the circuit.

this seems to be the problem area.

Any thoughts?

I am getting a 70.2 mA draw on the battery at all time.

now I guess I can go back through the parasitic load diagnostics and try to find the problem.

I can't believe I am the first to have this problem.

Thanks for all your help. I'll try this out.

My meter only reads to 30mA, so i don't know how high the mA load is.

Sorry but I do not understand the sticky out label reference, Merry Christmas.

How much over 30ma is the load? At around 30, it would be considered normal and I would recomend changing the battery. If it is a lot higher then something is remaining powered up, and you will have to find it. Removing the fuses to isolate the draw is a good first step, but there are some components that have fusable links, have you disconnected the links? I hope this helps a little bit.

I haven't tryed any fusable links, I guess I had better get an electical schematic to find them.

Do you think the dealer will give me one?

Help! my 98 ES300 battery drains after several days of not being driven.

All the diagnostics known to me have not found the problem.

charging system good

battery good

parasitic load test shows over 30mA load at all times. no fusable loads seem to be the problem.

Any suggestions?
