Why should a capacitor PN 8830 be installed with a retard control?
The purpose for the capacitor is to buffer the action of the “ON / OFF” switch to the battery in a monetary open condition due to severe tire shake or vibration. With the capacitor in place the retard box would never see the open condition, if it did, the entire ignition system would lose power (Shut completely off) and re-ignite again, possibly resulting in engine damage.
