How do I test a 69 buick clock to see if it works??? All I have is the clock. No wiring, no dash nothing.... Thanks Michael
if it only has 2 terminals ... using an ohm meter, you could test each of them to the clock's metal "body" to see if one is grounded (.1 ohms or less) directly to the clock's body metal.... if it is, then it would be the ground terminal and the other terminal would most likely be for 12 volts ... if your clock has more than 2 termials, wait for more advice to show up on this thread from other's .
This clock may have up to three terminals, including one for the illumination. One will be ground, one will be for illumination, and the last will be for the solenoid that winds the clock. This clock uses a balance wheel type movement; 12 volts is necessary to keep it wound. If working properly, the clock should audibly clunk every two minutes or so. This will be the clock being wound. When wound, it should audibly tick, indicating normal operation. This ticking may require you to put your ear very near the case, but you should be able to hear it. If it has a sweep second hand, it should move. These clocks were mechanical, with their requisite problems with wear. Ray
68/69 clocks have only one terminal, the body of the unit is case grounded, connect a gator clip from the metal body of the clock to ground then connect the one terminal to 12v. If it works more than sporatically I'll be stunned I had five of them and not one worked properly. I sent one out for quartz conversion and it keeps perfect time now:TU:
