Got started on this. Leaving hood up, can't find any ajar switch.
Tried to leave driver's door open (only door that needs to be open to get at the fuse boxes in there) and jam the open switch with a screwdriver (no luck there) and with other things still no luck. Leaving it closed for now to at least get the amps reading an hour from now.
There is a sort of spring- loaded lever above the door latch which is mounted in the end of the back half door (which is a "suicide" facing door that opens from the front end). There is also a push button in the end of the driver's door higher up. I am guessing it is the lever thing that needs "fooling" based on advice I got above, but I have not found a way to jam it yet.
I rigged up a jumper wire between the neg post and the disconnected neg terminal, and have a wire nut in the middle of that wire. I have the meter set to amps with a clamp fixed to one lead and the other lead jammed in the neg post so I can clamp the meter to the neg wire terminal as desired.
So with the jumper wire connected via wire nut, voltage is 13.2 (from just having the maintainer taken off), and amps on the meter is zero.
With the meter still connected and showing zero amps, when the jumper wire nut is taken off the amps jump to 0.20 amps. I don't know what happened to that 0.74 amps from before.
So back later with the amps reading I get after the hour long wait.
EDIT--it only dropped to 0.18 amps. Not clear I got anything done. Probably messed up the procedure somehow. Anyway, I will just leave the battery maintainer on at home and live with that.
Thanks all for the info and tips on this whole thing. Back to regular programming.
