You would think you would have thrown a 51 or a 52. But I did have exactly
the same problem last month. It would give a 52, but it took about three
days for a 21 to throw, plus it was giving them out of order for a while. I
thought the return should run between .2 and .8 volts every second, plus I
remember something about the value having to cross the .5 volt line twice a
second. Oh well, glad to know I'm not alone with my little problems Biff
