I repaired my clock in my 1967 corvette. it runs fine hooking it up to a power source outside the car. runs for hours. when I install it in my car after about 15-20 minutes it stops. I take it out and hook it up again works fine. This is a mechanical clock. do you have to reset/or wind after some many minutes. Any help?

If it runs fine on the bench, it should do the same in the car, if it's getting power and ground when installed. Check both cavities in the harness connector to make sure one has full-time power (key on or off) and the other has no resistance to a known good ground. It's a mechanical clock, but it's electrically wound - you shouldn't have to do anything to it except to set the time. -

In addition to what John said, The clock winding mechanism recycles about every 3 to 5 minutes. You probably noticed this on the bench. You'll here the reset noise if things are quiet where you are working.
The accuracy (gain/lose time) is adjusted everytime you pull the reset knob and turn it. If your clock keep good time then try to hold the knob out as you set the time to avoid messing up the accuracy. This is described in the owners manual.Comment

Re: 1967 clock
there have been a few posts on clocks---when the battery has been disconnected for a length of time you need to do a couple of quick taps (quick touch) of the negative battery terminal to the post just before you put it on ---this will aid in preventing welding the points together on the clock windup solinoid---the spring usally does'nt get to go to the full unwind when power is available---the full unwind sometimes provides point tension a hair too long and can cause the points to weld together---just my 2 centsComment
