    I’m sure people are going to jump all over me for this but here goes: I’m surprised to see him touching the positive while his hand is on the frame and even more surprised to see him touching both terminals at the same time.

      The reason I came to no harm is because the voltage is not sufficient to pass through my skin. It takes at least 30 volts to even cause a tingling sensation and the battery is only 12 volts.

    i mistakenly plugged the negative first and got sparks, when i realized, i disconnected and started with red first and then the negative, and then i had smoke coming from the fuse block and blown the 30a fuse and the negative wire looked not so good at the the fuse terminal.

    My truck has two batteries and in haste disconnected both positives then put one back on. When I saw sparks I took the negative off both then put the positives on both then both negatives. I clearly wasn’t thinking. So now the instruments and some lights work but it doesn’t crank anymore. No sound at all. I can’t tell which battery cranks but is suspect it’s the passenger side battery. It’s ‘16 titan diesel, was trying to disconnect batteries before swapping out the fuel filters .

    Been having issues with car. I always have to jump it to get it going. Today but accident i took off positive first by accident cause it was late and dark. spark came and car shut off completely. Tried again wouldnt start.
    Should i try again tommorow? and yes it is a new battery aswell

    • @WrenchesToRiches

      Just check the voltage. Battery might need charged up a little. It's unlikely you did serious damage if you just made some sparks

      Could have bad alternator or not be well connected. You would need a multimeter to diagnose

      Probably not. Just misdiagnosed the original problem. Originally, before you replaced the battery, did the car die while running?
