battery drain

[tempforce]

i have a issue with battery drain.

i don't use my truck every day. and i've noticed that the battery drains over a week or two below ten volts. once i found it down to less than 9 volts, over three weeks of non-use. i now place the truck on a charger when it drops below 10 volts. i've already had to replace my batteries last summer, due to this problem. charging system works well, except i do notice the volt meter doesn't always charge above 13 volts while driving. i figure the guage is computer controlled, as my after market guage reads normal when the dash reads low. i do unplug my after market guage unit when i'm not going to use my truck for a few days, as i found that it also will drain the batteries.



is this normal computer drain on the batteries???



thanks. .

no.

use a clamp-on ammeter to find the problem disconnecting one thing at a time starting with the alternator.

Well of course it could be one of many differnt circuits drawing down the battery, particularly if you have added any accessories to existing circuits.

However, you MIGHT want to read this thread--

And see if it helps out. IIRC, the first fuse to pull is #51 and then see if the draw goes away.

Good Luck ... let us know what you find !!

Search links expire. Yes, you have to hook up an ammeter and pull fuses to locate the guilty circuit (and then find the defective part). The batteries should last a year or more but should be charged monthly if the truck is sitting.

Sorry about that-- here is the thread...
