How often does the C3 clock reset?

[Gary S.]

I can't seem to find this anywhere - it could be that I am asking the wrong question. When a properly working C3 clock is running, how often does it before run before the contacts trip and wind the arm back? I am getting about 75 seconds or so which seems to short. I have it in my mind that this should be 2 1/2 minutes or more but I can't locate a source on it.

The clock stopped working so I pulled it out, cleaned it with contact cleaner got a needle oiler and put a couple of micro-drops on shaft pivot points and dry graphite lightly spotted on rotating components. The arm with the one side of the points that pivots when the contact trips it open only moves about 1/2 of its total capability. I can wind it manually and get many additional seconds.

Any help on the time issue? Still searching - off to the garage for Restorer articles on this.

Thank you,

Gary, the restored clock in my 70 resets at 88 seconds. It seems pretty accurate, and passed PV.

The GM book says 60-90 seconds. I just happened to read it earlier this week.

I am not questioning your statement, just asking. What book did you find that in? I was at a loss to figure out where to find that answer.

Installed a new clock in a car this week.
I might be able to find it back; it may have even been a photocopy of GM instructions that came with the clock.

60-90 seconds falls right with my clock but it sure seemed longer before. If you find the reference Patrick, pass it on please.

Well, I could have gone straight to the TIM&JG and it says "The contacts can be heard engaging the main spring winding solenoid ...roughly 90 second intervals. Hmmm....

Jay Leno ever call and ask you to write humor for him? I would have but my TIM&JG wasn't at my house until the other day.

Mine is at my house and has been for some time. I never thought to look in the most obvious place. DUHHH!
