    keyword=Right bogie system

    The right Bogie system is down. While trying to determine why the left Q2 quenched we discovered that the right bogie system was also down. The primary problem was a faulty solid state relay that was lowering the 208 voltage and generating phase loss on the drive power supply. After replacing the relay the rely again faulted out. It was then determined that the drive power supply must be damaging the solid state relay. Replaced the inner-bogie power supply and solid state relay. The power supply issue has been corrected however the Forward and reverse clamp on the inner-brake board in not working. Will troubleshoot and repair during beam studies tomorrow.
