Solenoids can get quite warm if active for extended periods of time, but it should only have current running through it for a fraction of a second once every 1-2 minutes (assuming your clock is designed similarly) and so I doubt it should get super hot. With that being said, I have not done tests on my clock with it outside the case, so I cannot say for sure that the solenoid does not get too hot to touch; however, I do know that the case does not get hot when it is operating. With that being said, I would first check the voltage going to the clock and make sure that it is not more than what the clock is designed for. You might have to look that voltage up. It also shouldn't be too low (10 V might not be enough for proper operation if the clock needs 12 V). If the voltage is correct, check to see if there is a continuous current flow. If so, it would indicate a short somewhere, possibly due to a bad solenoid or a problem in the circuit after the solenoid. That continuous current, even if small, through a small solenoid could generate a lot of heat. If both the voltage and current are good, then perhaps running hot is just normal. I assume you are testing the clock outside its case and outside of the car, so if the above tests are good and the clock works, I wouldn't worry too much about it so long as when it is in the case, the case does not become hot to the touch. Sorry for the long-winded answer, but I hope this helps!
Hard to say. I haven't seen it in normal operation. However, if I remember correctly, pushing the arm to full extension lets this clock run for 2- 2 1/2 minutes. It runs somewhere between 1- 1 1/2 minutes in regular operation, so it probably extends 1/2 to 3/4 the length of the spring. Maybe that's something I could look at in an updated video. Hope this helps.

Very interesting thank you I will try to work on mine on Friday
very nice I will apply this info to my clock cheers Dan
Glad to help! I hope this strategy will work for you.
Well explained.
My clock in my Saab v4 sort of works but it gets really warm, the solenoid it’s almost burning hot, are they supposted to be that hot?

How far does it push the arm after the contact was made?
Hard to say. I haven't seen it in normal operation. However, if I remember correctly, pushing the arm to full extension lets this clock run for 2- 2 1/2 minutes.

How many voltage supply to this clock?
@@kythele9502 12 V. This is the typical voltage. I believe some earlier clocks ran on 6 V.
