CPU-95 DIGITAL IGNITION SYSTEM
13.0 SECONDARY WIRING
13.1
Mount the ignition coils as close as possible to the engine spark
plugs consistent with a secure mounting and avoidance of tempera-
tures in excess of 185°F (85°C).
13.2
The spark plug leads should be fabricated from silicone insulated 7 mm
cable with suitable terminals and silicone spark plug boots. The use of
leads with resistor spark plug boots (Altronic series 5932xx-xx) is recom-
mended to minimize interference from emitted RFI on the operation
of other nearby electronic equipment. Another option is the use of sup-
pression ignition cable (Altronic part no. 503185). It is also essential to
keep spark plug leads as short as possible and in all cases not longer
than 24 inches (600 mm). Spark plug leads should be kept at least 2 inches
(50 mm) away from any grounded engine part. In deep spark plug wells,
use rigid insulated extenders projecting out of the well.
13.3
The use of a clear silicone grease such as Dow Corning DC-4, G.E. G-623
or GC Electronics Z5, is recommended for all high-tension connections
and boots. This material helps seal out moisture and prevent corro-
sion from atmospheric sources.
