solve many problems you are likely to encounter.
4.
Capacitors will bypass spikes of electricity, such as those pulses which run
the spark plug to ground. Small capacitors are fine; however, if you add
too much capacitance to ground, you will flatten the ignition spike and
reduce the intensity of the spark. The arrival time of the spark will also be
delayed because the capacitor which you use will slow the rise time of the
spark pulse.
With too much capacitance, the spark voltage may drop from 20,000 volts
to 5,000 volts which isn't enough to cause a spark in the engine. For this
reason, the only place you want to put a capacitor is on the primary side
of the ignition coil.
5.
Shielding the distributor is the next most likely means to reduce noise.
This may not sound graceful, but occasionally a brute force approach is
needed.
6.
Wheel static may be eliminated with brushes, and accessory noise may be
isolated by turning on and off items such as heater fans and air con-
ditioners.
