More 555

O.K. guy's, Its my turn to install the cone shaped hat. I was using an
automotive batt. charger. I guess the rectified output is double the
input i.e. 120hz.

  Now my next question... The circut is designed for 10Khz but 2
injectors that Ive tried dont seem to like much more than 5-600Hz at
about 60% duty. Anyone had experience with this?

TIA
