I just did a parasitic drain test. I hooked up a 10A fused ammeter in series with the negative terminal and cable. I had all fuses in place. I then turned the key to the RUN position then back to the LOCK position. The meter read 4.5A until the interior lights went out, then it read 1500mA. The radio was off, but the clock was still illuminated. Also, the lights on the window controls were illuminated. WHen i opened the door, the clock turned off and the lights turned off. The meter now read 400mA. Is that excessive?
I did the test again and this time instead of opening the door I pulled the Accessory Delay relay. This also dropped the reading to 400mA.
I tried many other combinations. Basically, the radio draws 100mA when it is off and about 1 amp when it is on. With the radio fuse pulled, the reading was reading was 560mA after waiting a minute when turning key to LOCK and dropped to 300mA when the Accessory Delay relay was pulled. I also waited about 10 minutes after turning key to LOCK and the Accesory Delay relay switched on its own and turned off the radio and the window control lights.
Having fuse 107 (Power Door Locks (BSM)) didnt have an effect on the test at all. I could not tell a difference in amperage whether it was in or out.
After running this test, my only concern is whether 400mA is excessive or not. I have read that 500mA is the limit, but wasnt sure.
