jeffery Posted July 5, 2014 Share Posted July 5, 2014 I drive 50 to 100 miles and loose ignition. clean points or spray with silicone spray good for another 50 to 100 cycle. - repeat-repeat-repeat - any ideas ?? Link to comment Share on other sites More sharing options...
Batwing-8 Posted July 6, 2014 Share Posted July 6, 2014 Jeffery: Judging from your brief description, were this my car, I'd install a new set of points and a condenser, and not spray anything on them. Then I'd try a different ignition coil. A deteriorating coil can temporarily "die" when it gets hot. Also, be sure all your electrical connections in the primary ignition circuit (battery to the points) are tight and clean; bare-metal to bare-metal. A weak electrical connection can drop voltage as it warms. Link to comment Share on other sites More sharing options...
drdon Posted July 6, 2014 Share Posted July 6, 2014 Don't forget to replace the condenser when replacing the points. It can be the source of many ignition problems. Link to comment Share on other sites More sharing options...
drdon Posted July 6, 2014 Share Posted July 6, 2014 Oops Batwing said condenser as well. My bad. Link to comment Share on other sites More sharing options...
jeffery Posted July 6, 2014 Author Share Posted July 6, 2014 Ive changed coil pts,cond.& even wiring.The spray came about as a last resort blocking traffic. Usually it happens after being run & restarted.If it restarts at all Link to comment Share on other sites More sharing options...
bifda Posted July 6, 2014 Share Posted July 6, 2014 Try a new distributor cap, it maybe cracked and spraying with silicone spray may temporarily be insulating the crack, but as time goes on it shorts to earth again.Wayne Link to comment Share on other sites More sharing options...
drdon Posted July 6, 2014 Share Posted July 6, 2014 Bifda has a good thought for sure, and here is another idea- ie from a VW Bug that would do the same thing many years ago. I had taken it to several mechanics and all that did was lighten my wallet. Finally, I was just chatting with a VW bug "nut" and he said " You have a worn out distributor. You need to replace the whole thing." I did, and viola, the problem was completely cleared up! I realize this is an expensive choice, but maybe, just maybe??? He shared that it happened to "Bugs" when they got hot. Sounds as if your problem is similar??? Link to comment Share on other sites More sharing options...
studerex Posted July 7, 2014 Share Posted July 7, 2014 Sounds like a bad coil, but do you have overdrive? If so the kickdown switch might be grounding. Link to comment Share on other sites More sharing options...
Spinneyhill Posted July 10, 2014 Share Posted July 10, 2014 Might there be an intermittent earthing problem? The original battery earth was from battery to battery box (and thence chassis) to engine.All the connectors in the Studebaker ignition system are zinc or cadmium plated brass on steel bolts and nuts - i.e. each connection is a wee galvanic cell. The zinc corrodes and the corrosion products do not conduct well. I had about 2 Volts at the coil when I eventually measured it. No wonder it was hard to start, hard to keep running and ran poorly.

Larry W Posted July 11, 2014 Share Posted July 11, 2014 Sounds like a bad coil, but do you have overdrive? If so the kickdown switch might be grounding.Quick check for the coil; the next time it dies, spray some water on the body of the coil to cool it down, and then see if the engine immediately restarts.
