I would like to know the current drawn and mechanism discharge time for the OE electro-mechanical Clock instrument fitted to early 1800 vehicles, for the purpose of including this in a Sw-Em.com tech article. These Clocks do discharge the vehicle Battery (albeit slowly) by this mechanism. These Clocks work by periodically energizing an internal micro-solenoid, which charges a spring-mechanism, which then powers a typical escapement clock-mechanism for a period of time until the spring is discharged, a contact is closed, activating solenoid again, repeating the sequence. If you have one of these Clocks, and it is functional, please measure and contact me with solenoid current, and duration until next charging. TIA!

Ron, when you say "early" 1800, are you saying that one out of an E or ES won't work?
Also, does mechanism discharge mean how long it takes the spring to wind down?

Chris;

Yes, I mean carburated 1800s for now...

...and yes, also...solenoid "charges" Spring, which powers mechanism, and slowly discharges spring as it does...
