Distributor Cap: Testing and Inspection
Cap Inspection - External - Typical
Cap Inspection - Internal - Typical
Remove the distributor cap and wipe it clean with a dry lint free cloth. Visually inspect the cap for cracks, carbon paths, broken towers or damaged rotor
button. Also check for white deposits on the inside (caused by condensation entering the cap through cracks). Replace any cap that displays charred or
eroded terminals. The machined surface of a terminal end (faces toward rotor) will indicate some evidence of erosion from normal operation. Examine
the terminal ends for evidence of mechanical interference with the rotor tip.
