Re: PCBs in ASR



It seems that this is a ripe area for P2.  The
PCBs ~should be~ found only in one or two
locations in any vehicle, clearly identifiable and
removable.  That would be in the electrical system
supporting the starter and perhaps on the
alternator, since those are the only places where
a capacitor of any size is needed in an
automobile.
