Over night Battery Drain
Any Ideas on what is causing this over night battery drain? I can drive around all day doing shopping chores and such and truck will start all day long, but, park it at night, and will not start in the morning.
Have done the test with the light to the battery ground and positive post with the ground cable disconnected and there is no indication of a draw.
What else should I check, where else should I look...
A curiosity occurred a while back when it was doing the same thing I am describing now...I was disconnecting the negative cable when parking the truck to save the battery, then when I was away the battery was stolen out of the truck, I won't go into the Homer Moment, that caused that to happen. Subsequently I had to purchase a new battery, and the overnite drain abated, now I know that some might say...well sure it was a new battery...but, it never drained away for over a year until I parked the truck this past winter.
I charged the battery with a trickle charger for about 36 hours until the charger indicated that it was full, then put it back into the truck, and my over night drain returned.
I am baffled to say the least, I should also mention that vehicle electricity has always been a challenge for me, so short of taking it to an auto electric shop for diagnosis, any information you provide for me here is most certainly appreciated, but, needs to be very specific.
Thank you all in advance for any information that will save me any time and money, and rid me of this extremely annoying problem.
A PS: to the above, this also started when I had the transmission rebuilt, and installed a new clutch, a removal and reinstall I did myself.
