http://www.oz1jhm.dk/content/wetting-current-and-cw-paddles I have an amusing story along these lines. Coming home one night from a late date with my wife, we came upon a car stalled at a light. It was perhaps 22-2300. I got out to see what I might do. The car would not start. The usual clicking from the starter, usually indicating a dead battery. Short version. I asked the other driver to turn on the radio. It worked. I then asked them to turn the headlamps. They worked. After a bit of additional troubleshooting, during which I did nothing to the car, I suggested they turn on the headlamps and attempt to start the car. It started. Arriving home, my wife promptly challenged me, saying that common practice is to turn off all electrics to preserve battery charge, and then attempt to start the car. I told her that the battery was fine, and I opined as time passed that there was possibly too much corrosion on the terminals. When the starter circuit engaged, it didn't draw enough current to move the solenoid fully. By turning on the headlamps, which are a large resistive load, a current path was generated through the oxidation. Then the starter was able to draw enough current to fully engage the solenoid. Of course, this may have been a fortunate coincidence. ;-) ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
