89 xj and I have a 12.5 ma drain on battery. took all fuses out ,all door pins have been removed ,no glove box light or cig lighter or clock or radio in car . , unpluged the small plug on the ecu and drain went away, any thoughts

 

I checked my 90 a few weeks ago. Was surprised to see zero. Had thought it would have some little "ghost" draw. 12/100th's, that's about 3 A/Hr./day. Would hammer a battery in in less then a month. (if I got that right). You might catch cruiser54, PM him or leave a message on his member deal.

 

I have the same problem with my 88. Leave it sit for a day and its dead. i have 18ma draw, limit is 36ma. i took out all fuses and everything... nothing changed. So anyway, one way to do it (as i have been so my battery doesn't drain) is pull off the negative cable when you park it. Does this get annoying? YES!!! is it effective? Yeah. I have no idea what is draining mine, but this keeps the battery charged.

 

I would step out and check mine again but.....I just installed 703 injectors last week. The "official" line is Renix has no memory and can't be "reset" (nothing to reset). That said both the FSM, and some guys talking of injector swap's refer to some sort of memory in an ECU. Soooo, just to be through I'm running a tank before disconnecting my battery. Then I'll disconnect it overnight and check millage again from there.
