Usually loses charge overnight after I get it running.
Expert:  EricFromCT replied 10 months ago.

You may have a serious draw on the battery. Have you checked the charging voltage with a meter when the truck is running?

Customer: replied 10 months ago.
No not yet, need to purchase a meter
Expert:  EricFromCT replied 10 months ago.

Ok. If you have corroded battery terminals the battery may not be getting a full charge from the alternator. Or you could have a draw from a module, or installed accessory that is not shutting down when the key is off, causing your battery to die. TO check for that you need a good meter that can do AMPS, and you need to hook the meter up in-line with the battery cable and see what type of amps are drawing on the battery.

Will try
Expert:  EricFromCT replied 10 months ago.

Ok. WHen you get to the point of checking for a draw, there are several videos on youtube that show you how to check for a battery draw.
