1991 Nissan Pathfinder stereo issue

[Sutter21]

Ive got a 1991 Nissan Pathfinder and the stereo doesn't work. Its been in my family for 10 years and I recently just started driving. Every thing runs great and works except for the stereo. It is still stock and no modifications have been made to any part of the stereo system. Ive checked all of the fuses under the steering wheel. Everything else works. I pulled the unit out and the connections all seems fine except the main power source has 0v. Does any one know if there is another fuse located along the main power cable? Or maybe this another issue all together. Ive looked but couldn't find anything.

Memory wire should have 12v always. Main power should be zero until you turn the keys to on and/ or acc. (accessory). You can get the factory wiring and such from the FSM if you go to our "Service Manuals" link at the top of our web-pages. Maybe the ground wire lost connection and needs to be re-established.
