I changed my oil about a week ago, got the book out of the glove box to document the date and mileage, put back in box and parked truck. Today I was prepping our 5er for an upcoming trip and after getting it all ready and topping all the tires off on both the trailer and truck went to fire up the truck. Turned on the ignition to "WTS" for the plugs to heat up and noticed the gauges on the pillar were acting weird. Then I noticed the light went out too soon, tried to start and it was almost totally dead. After a few brief moments of panic I went around to get the book out of the glove box to look at the papers on the batteries when I noticed that the glove box was open just a tad and the light was on. Crap, I found I had put the manual back too close to the light switch and set up a situation where I caused the batteries to drain. This hopefully will not happen again. Just a heads up to keep an eye out on the small things that you never expect. just sayin....
For me it was the voltmeter stuck in the cigar lighter socket. Drove another vehicle for a while and forgot it was in there, slowly sucking. Batteries were dead flat 2 months later when I hopped in expecting to go places. At this point I've seen the voltage in relation to the sound of the starting process and brightness of the lights so many times, I can forgo the voltage and just look and listen. I'll plug in the voltmeter when something is amiss.
I forgot to mention, I have the OBDLink MX OBDII adapter that powers down when not in use. I left it plugged in for three months without using the truck - zero problems with battery drain.
ya know Rich, i was just thinking about that yesterday if i could leave it plugged in on the 14 or not.
good to know that it in fact does power off when not in use.
