I finally decided to look for the parasitic draw on my Rangers battery. This has actually been a problem for a very long time, but ignored it because I usually disconnect the battery when it sits for a while.
Well, no more!!
Take a screwdriver and push your door latched closed so you can leave it open. Otherwise, the dome light will be on. You may want to do it on both doors so you can get in both sides without interfering with the test.
This looks like a mess, but I disconnected the (-) cable and used some jumpers with alligator clips to connect my multimeter between the (-) cable and the (-) terminal on the battery.
With the dome light off and nothing on meter showed that the battery had a 0.28 amp draw.
You cannot start the test here. Some people will start pulling fuses looking for the reading to drop, and blame it on the fuse for the instrument cluster. You have to wait a good 45-minutes for the battery saver mode to kick in.
After waiting and checking back, the amps had dropped to 0.12 amps.
I believe the normal acceptable range is 0.01 - 0.07. This is where people will start pulling fuses and relays trying to find the faulty circuit.
For me, I got lucky. I decided to start with the accessories that I had added to the truck. There are a couple of relays that operate my off-road lights. Upon pulling the fuse to the second relay, my amp draw dropped to 0.01.
Stupid relay.
