Alternator/Generator Whine
This type of interference is characterised by a high-pitched whine which varies with engine speed. A
0.5 µF coaxial capacitor (Motorola Part No. 8C82571B01) can be used to bypass the whine. For
generators, the capacitors is connected in the armature lead. Never use a capacitor in the field lead.
Use the field suppressor assembly supplied in the TLN6252A Noise Reduction Kit. For alternators,
the capacitor is connected in the lead to the battery post (see figure 2-6 and 2-7).
