Why does the generator spark plug have a weak spark or even no fire?

Ito Power will be happy to answer your questions: the battery is discharged, the poles are dirty or have poor contact, the entire vehicle line is poorly grounded, the low voltage line is short- circuit or gap is open; in distributor power off contact (platinum) is too large or too large Contact small, ablation or bad; capacitor short circuit, open circuit, leakage or breakdown, failure and damage of distributor cover and distributor cap; too much contact or oxide between the conductive part of the distributor cap and the distributor cover socket.
