97 TJ electrical

[RonaldL]

My 97 TJ pulls about 4mA with everything turned off. Is this normal or should I be looking for a problem? Thanks for any help. Ron

Ignition-Off Draw (IOD) refers to power being drained from the battery with the ignition switch in the Off position. A normal vehicle electrical system will draw from 5 to 25 milliamperes (0.005 - 0.025 ampere) with the ignition switch in the Off position, and all non-ignition controlled circuits in proper working order. The 25 milliamperes are needed to supply Powertrain Control Module (PCM) memory, digital clock memory, and electronically tuned radio memory.
A vehicle that has not been operated for approximately 20 days, may discharge the battery to an inadequate level. When a vehicle will not be used for 20 days or more (stored), remove the IOD fuse from the Power Distribution Center (PDC) This will reduce battery discharging.
Excessive IOD can be caused by:

• Electrical items left on
• Faulty or improperly adjusted switches
• An internally shorted generator
• Intermittent shorts in the wiring.

Thanks for the information. I forgot all about my clock and didn't know about the PCM
