Is this normal?I used a multimeter to measure DC current i series with the battery, the reading is 65 miliamps. According to guides online, the normal current drain for a car when it's turned off is 25-50 mA, so this seems to be too high. If I remove fuse #21, the drain drops to 4 mA.According to manual, fuse #21 powers the interior lights, trunk lights, torch charger, glove box lights, radio, clock and on board computer.None of my lights stay on when the car is shut off, clock only using about 2mA, on board computer I did not remove, but I assume it should be fine. That only leaves the radio, mine is a Kenwood unit, does this mean whoever installed the radio did not do it properly, or perhaps it is old and is no longer entering standby mode properly?Next question is that I noticed that some of my fuses don't match the ones in the manual. Some have been replaced with higher amp fuses, and one with a lower one. Are our CKD models here different from the specs in the manual?</p></blockquote><p></p>
