I need to find out what this little green box's (a fuse or diode of some kind) part # is or what it is called.The component in question is connected to the alternator and the fuse relay control boxes mounted on the left side of the engine compartment (orientation is that you are looking into the engine compartment from the front end) via a yellow wire with red dots (looks to be factory wires), on the side that leads to the Fuse relay boxes, the wire has a black stripe.
Not much else that I can say other than the instription on the green box has the nissan logo, under it, a triangle with a short line coming from the peak of the triangle going up, where the peak and the line meet, there is a line crossing this junction running parallel to the base of the triangle. Below center at the base of the triangle there is a short line going down (perpendicular to the base of the triangle). Finally below that, there is a "1.1A" listed.
On the other side of this green box, there is an indication on either side of an orange cap that seems to hold the two wires in place that reads MB3 on one side and the other reads M02FM.
I imagine that these are some sort of factory index and probably wouldn't be in any manual.
I have had my Alternator tested twice and it is good as far as I know but the truck will not charge the battery, and I think that this little green box has something to do with it. I've searched everywhere (locally and on the internet) and have had no luck in determining what it is.
