All,
I have a ’72 Keinzle Motometer electromechanical clock. The mechanicals work fine and were even oiled with clock oil. The electrical charge circuit is the problem. There is a small spark at contact closing but the circuit does not restart/recharge the mechanical sequence.
I repaired the fusible link first with regular solder and then replaced with low temp solder (70°C). The contacts were filed and alignment checked. The resistor is good (as well as a substitute put in – if anyone cares resistor is 48.8W on mine). There is continuity throughout the circuit and the test power supply has been tested for proper output. I have read over every article I could find on this (2002FAQ, VW, Porsche, clock forums, etc.) and can’t find any details on the electricals (so no kittens here).
My hypothesis is that the coil has shorted across several windings. Does this sound reasonable or is there something I have overlooked?
What is the value of the inductor? Anyone replaced one? Anyone have a good one laying around in a bad clock they will part with?
TIA,
--John
