Does your trip odometer actually work?
Had my speedo and tach rebuilt a year or so ago, just getting around to installing them, and I installed the trip odometer cable into the housing. Pushing to reset or turning it has no effect on the trip odometer. Wondering how it actually works? Do you push to reset to zero, or turn it to reset? I had both odometers reset to zero when they were rebuilt.
Never worked prior to the rebuild, so I'm not sure.
Thanks,
Rob

Trip odo does not work on my '68, but neither does the regular odo. The speedo head is original and needs replacement. Trip and regular odo work in my '80.
Push to reset.

Here are a couple of pictures of what the reset mechanism looks like and how it works. When the cable is pushed in it forces that brass gear away from the drive gear and at the same time engages the gear on the end of the reset cable. You need to turn the cable clockwise to reset the trip. I have had a few of these speedometers apart and the reason that some trips do not work is that the little brass gear gets dirty on the shaft and the spring is not strong enough to push the gear back to mesh with the main drive gear. Also if the reset cable does not fully release, the gear will not drop back to mesh with the main drive gear. If the main odometer is working and your trip is not then you have one of the problems I have mentioned above. I have never seen any of the trip gears stripped, it has always been a cable problem or a barss gear that no longer slides properly.

My 76 works, you push the button and turn. If you turn it one way it goes up 1/10 at a time. If you turn it the other way it turns backwards until all the digits are the same, then you can reset it at all zeros or 999, 888 etc .
That always seemed a little odd. Is that they are supposed to work?

Mine works now. I took my speedo apart last winter and made the and made the fix. When I put it back in though, I left the reset cable off because it had a kink in it and that was keeping it from working. I had a thread running about the fix of the speedo.

I reset mine once...when I bought the car 5 years ago. That way I could start my mileage/trip log at "0000". The regular odometer is getting ready to turn over for the second time in about 20 miles. And I think the car is [now] in better condition than it was when it was 5 years old! It still has the original engine (bored .040 over), most of the original components, and runs like a top...
