NOTE: Right and left side Sonic Boom sensors are
identical so they can be exchanged to assist in trouble-
shooting. If a problem follows the exchanged sensor, an
electrical problem likely exists with the sensor. If the
problem remains unchanged, something other than the
sensor is the problem source (e.g. switch, circuit wiring).
