Nissan Repair: 94 pathfinde Spedo, pathfinde, multimeter

Question
i have 94 pathfinder and the speedo stopped working. i already replaced my sensor and still does not work. my odometer works though and when i put the key in start/on position the speedo bouces to 10mph(engine not running just on position). even tried to check SMJ running from sensor it gave me the same reading with my multimeter. could it be the ECM? or the actual speedo? thanks!

Answer
my guess would be the speedometer inside the gauge cluster.  only true way to check is with a multimeter and a factory service manual to find which points to test.  but, if you can get ahold of a working pathfinder cluster for cheap, i would try that route.  good luck.
