    I 've been trying to diagnose why the truck just keeps randomly dying and coming back to life. At idle or while moving.
    All roads lead to the power and distribution box. I tried to continue past that diagnose wise, and was getting now where. Another driver told me if the red light is on on the box then the box is bad.

    This morning I changed the box and as soon as I fired it up the red light cam back on.

    After it warms up I'm going to test ride it.
    My question is does the red light mean the new box is no better than the old one?
