My 96 with 278k on the clock has a couple of wire harness connectors going to the positive battery terminal's clamp. This evening, the car would not start on the way home from work, no power to anything, as if the battery had been removed. When I wiggled the positive battery terminal's connectors, power would come on internmittently. I pulled out the two connectors and carefully cleaned them. One was hard to remove and had vlisible corrosion, which I scraped away, then sprayed Deoxit on the connecting surfaces. That didn't restore power, but pulling upward on the postive post assembly did. It seems that pulling the two connectors upwards does the trick. Is anyone here familiar with this problem?

 

Can you post some pictures so we can see how corroded the connections are?

The OE part is 24110-44U00.

 

I cleaned them up pretty well so there isn't much visible corrosion now. If I replace that part of the harness, I suspect the trouble will be resolved. Thanks a lot for posting that photo and part number. Where would you order it from, the local Nissan dealer?
