no spark on 1991 Acura Integra

No battery voltage to distributer, no voltage on the BLK/YEL wire coming to the dist. Where does this wire get the voltage? In the recent past I have replaced the coil TWICE, the hi-tension out put conection was cracked and burned, mabe moisture getting into the cap? Need you expertise.
Thanks, Jim

The black yellow wire gets power directly from the ignition switch. The electrical portion of the ignition switch is a relatively high failure item.
The White/Black wire at the ignition switch is battery live if it has no power the 50 or 70 amp main fuse has blown.
