Warren99 Posted July 9, 2018 Author Share Posted July 9, 2018 Yeah I'm just going to keep on tinkering with it, and probably try to take off and realign the needle the best I can. At this point, the worst outcome is that it breaks, or just can't be fixed. Best, it gets fixed. Either way, I'll get to learn something new about it. Also, I always liked the look of the Renix anyways so it's just another reason for me to want to look for another, but hopefully I can get this one to work.

HOrnbrod Posted July 10, 2018 Share Posted July 10, 2018 Heck ya, go for it. Be careful popping the needle. I've gotten them off okay using a couple of wooden Popsicle sticks applying as equal pressure as possible on opposite sides. Good luck.. Link to comment Share on other sites More sharing options...

Both front and back pics are identical. The large sweep and fonnt seems to match the 120 mph police calibrated speedometer on the H.O Cherokee. Long term project has been to "fit" this tach and 120 mph speedometer into a full guage cluster. Link to comment Share on other sites More sharing options...

If it came from a V6 and you're using it with a I6, it should be okay. You can use the diagnostic connectors under the hood to connect the tach and bypass the dashboard wiring. On the passenger side, near the bank of relays, there are two rectangular connectors with yellow covers on them. The smaller one has the output and ground connections for testing a tachometer.

Warren99 Posted July 13, 2018 Author Share Posted July 13, 2018 I already used it in the dash. We used an rpm reader to see what it was idling at. While it was running I put the needle on it at the shown rpm. Then, I held it at 3,500, and the reader showed something like 1,700. Basically, I'm just going to "scrap" this one and keep looking for another. If I see a renix, I'll definitely be getting one, and if I have too, I'll just return it. If it works, I'll just return the old one. Link to comment Share on other sites More sharing options...
