The first company which responded to my inquiry, yesterday, was Classic Auto Electric, of McPherson IL, classicautoelectric.com , and its owner, Joe Dickhut, has been very helpful and informative. He can replace the points & service the clock for $125.00, and, for $25bux more he will do some electrical magic that will provide an "alternate route" for the current to bypass(?) the points and greatly prolong the working life of the clock. He said this, most recently, and provided a photo of badly deteriorated points. Neil Vedder This is exactly what the points look like as they deteriorate. The residue you can see alongside this point is actually material that has been "blown away" by the repeated arcing of the points. You can file the surface "clean" again, but when you file the surface you remove more of the point material. If you file the points very many times, there will soon be no points left. At that point (forgive the pun) you are out of luck because the points are not replaceable. On 2/10/2012 12:35 AM, Dave Homstad wrote:The "contact points " are probably corroded. If you can get the cover off to expose them, an ignition points file might fix them. When the main spring winds down, it causes the points to close. The points then activate a solenoid that rewinds the main spring. About every 10 minutes. If the points are too corroded or dirty (oil doesn't help), the electrical contact doesn't make. WD40 lubricates the mechanism and allows a dirty/sticky works to move, for a while. When the battery is weak, the points may close but there may not be enough voltage to operate the solenoid. It just sits there passing current until it overheats and burns out the solenoid's coil. Sticky works may do the same thing. there is a simple easy to implement impediment to arc'ing, well used in the telecom industry when all the telephone switching was electro-mechanical, a passive resister/capacitor across the powersource and ground at the closest point you can get to. really cuts down on the arcing.
