| All sensitive
electronic equipment used today incorporates solid state components
and semiconductors. This type of equipment is prone to failure
due to the regular occurrence of high voltage surges, spikes,
RFI (Radio Frequency Interference) and EMI (Electromagnetic
Interference).
Spikes and surges occur whenever on inductive load is connected
or disconnected across the power supply and can generate spikes
and surges greater than a 1,000V DC.
They are caused by many types of standard equipment in every
day use and include, starter motors, faulty wiring, alternator
or voltage regulators, water pumps, fuel pumps and even the
windscreen wipers.
Spikes and Surges if they have sufficient energy will cause
on immediate equipment failure. Each time you start up or
shut down your engine, high voltage surges and spikes are
generated and chip away at the semi-conductor junctions and
other sensitive components slowly destroying them, until one
day in a weakened condition a transistor, IC chip or another
component fails.
