. Power to Distributor Test. Turn ignition OFF. Disconnect the 2-P connector from the distributor. Turn the ignition switch ON. Measure voltage between BLK/YEL (+) terminal and body ground. There should be 12+ volts read. If not, repair open in BLK/YEL wire between the 2-P connector and ignition switch.

. Check ignition switch for wear, pitting, or melting.

. Only install a genuine Honda distributor. Over 50% of new aftermarket distributors for Hondas don't work at AMHD.
