## Discrepancy

ON A/C WITH BUS-TIE OPEN, LEFT MAIN BUS (PS1) AND RIGHT MAIN BUS (PS2) SHOULD BE SEPARATED.  COULD NOT SEPARATE PS1 AND PS2.  THEY WERE INADVERTENTLY LINKED TOGETHER THROUGH A PULSELIGHT INSTALLATION.  HAD A PULSELIGHT SYSTEM INSTALLED, A COMPONENT OF THE PULSELIGHT SYSTEM WAS INCORRECTLY INSTALLED.  IT IS THE CURRENT LIMITER.
