Electrical issues Battries keep dying.

[Sesco4]

I but new Battries in my truck almost two tears ago. Lately I've been having problems with them going dead. I've had them load tested twice with the cables off and both times they tested good. Looking for suggestions on possible causes of this issue. Thanks in advance.

There are a thousand and one things that can cause the batteries to die. Start with the simple stuff. Make sure your cables are in good shape and clean, have your alternator tested then use a ammeter to measure the current draw with everything off. Work your way through the fuses and find what is causing the draw.
