Shane Posted February 15, 2011 Share Posted February 15, 2011 Okay, here's the story. I got an 89 Mj automatic,column shift,4x4. It had the idiot lights. Like everyone else I wanted the needles and tach. Did the switch (Got and installed all sending units). The gas gauge, battery gauge, oil gauge, and temp gauge work. The speedometer worked for a while then stopped. The tach does not work. What could the problem be? *Speedometer is connected.* What is a solution? Any and all help is appreciated.

webbjeepxj Posted February 15, 2011 Share Posted February 15, 2011 Clean the contacts and check the ground, should be integrated into the pack of wires, but I ended up re-grounding it because the original stuff didnt have enough wire to juice up the gauges. Sounds weird, but it worked ....... try it. Link to comment Share on other sites More sharing options...

webbjeepxj Posted February 17, 2011 Share Posted February 17, 2011 Does the tach not work, or jump around ...... ??? I have heard that some times the connectors can go bad and suffer from a little corosion over time .... Link to comment Share on other sites More sharing options...
