    So I am pretty sure I have to install a new battery and alternator or maybe just a new battery with the dual set up....I have a red top with 800CCA. It is about 3yrs old. I just had a plow put on this year and have led strobes. What do you guys think I should go with for a alternator and/or 2nd battery....I am thinking leave truck hooked up to red top and new battery run plow or should I go vice versa?

    So AAA just left my house....because truck was locked and dead battery...So with no juice truck would not unlock!!!!:mad: So AAA did a electrical system test and this is what they came up with:


    Voltage on Arrival: 4.04V
    Cause of no start: Unknown
    Battery Age: 3yrs Last started 1 day ago


    Voltage: 11.57V
    Measured: 320CCA
    Rated: 800CCA
    Temp: 39F

    He said, that my battery, alternator and charging system is all good. I am thinking it is the typical need second battery and or higher alternator and def thicker gauge wire....

    Any insight would be great

    Ck to see if you have a drain on your battery with the truck off. It's called a paracidic draw test. It'll tell you how many amps are being used while truck is off
