'99 Camry Battery draw

[cykle]

Battery draw on Courtesy light fuse circuit. Disconnected, dome lt, pwr mirror sw, dr. pwr seat, Headlight combination sw. Nothing appears to be on but drains battery? Any help appreciated,

Unless you have a shorted wire somewhere, the parasitic loads from the ECU and other electronics are very minimal. I would suspect you have a weak battery unless you recently replaced it.

Thanks for the reply, its not parasitic draw. New Battery. I'll disconnect the ECU and recheck. Aftermarket alarm disconnected, no pwr antenna, trunk light normal. Any other suggestions or common problems appreciated!

Do a dark current draw test. That's the current (measured in amperaege) that the car uses when the engine is off. Disconnect the negative battery cable terminal. Put a digital volt ohmeter between the battery post and the battery cable terminal, with the meter set to a milliamp scale. Normal draw should be 25 milliamps or less. If it is higher, pull fuses one at a time and retest. When you pull a fuse and the dark current drops to less than 25 milliamps, then you have found something protected by that fuse to be the offending device. Then you will have to disconnect each item protected by that fuse and retest until the draw drops to the normal range. Then, with the offending item issolated, you check the wiring to and from that item to find the problem.
