Please help! '72 c10 keeps draining my battery.
 

I am currently on my second battery for my '72 chevy c10. I just recently purchased the truck from a family member everything is original and for the most part works great. i have had the alternator tested and it tests exactly where it should be. i think possibly i could have a ground some where. ?????????????????????????????

pull one fuse at a time with a test light between the - battery post and cable..
light goes out.. there is your drain

if original, there is an external voltage regulator.
You need to see if your battery is getting charged, or if you have a key off drain.
