ACCEL COIL KIT # 140405
FORM 3-501-87 01/10
ACCEL’s 140405 high output coil for the Harley V-Twins
is designed to yield higher spark energy output than the
stock coils.
This kit comes complete with adjustable angle clamps and
brackets as well as extra heavy-duty ACCEL 8.8 silicone
insulated suppression core wires that are compatible with
the O.E.M. Harley-Davidson electronic ignition as well as
points-triggered ignition. For maximum output for the
Harley-Davidson engines from 1965-1979, using points-
triggered ignition, ACCEL recommends using ACCEL 8.8
Stainless Steel/Copper Core conductor. See an ACCEL
catalog for your specific application.
NOTE: DO NOT USE STAINLESS STEEL/COPPER CORE CONDUCTOR
WIRES WITH HARLEY-DAVIDSON MODELS THAT UTILIZE A FACTORY
ELECTRONIC IGNITION MODULE AS IGNITION MODULE DAMAGE MAY
RESULT.
NOTE: THE DESIGN CHARACTERISTICS OF THIS COIL REQUIRE
EXTRA LONG LAMINATIONS WHICH MAY REQUIRE THE REMOVAL
OR MODIFICATION OF SOME COIL COVERS. DO NOT REMOVE ANY
MATERIAL FROM THE LAMINATIONS.
Step 1
Be sure the ignition switch is in the “OFF” position.
Step 2
Remove original coil and mount ACCEL coil bracket clamps
and the coil itself with the towers in approximately the same
direction as the original coil. Tighten coil clamps snugly
enough to permit rotation of the coil body insuring that there
is no possibility that the coil’s molded shell or towers or towers
could come in contact with the frame, fuel tank, etc. under
vibration when running.
Step 3
Attach primary leads from the ignition switch and ignition
pick-up to either of the brass lead studs. These can be
installed to either stud without negatively affecting the system.
Step 4
Now install the 90° plug end boot of the ACCEL 8.8 wires to
each spark plug and route them as directly as possible to the
coil tower allowing slack to keep tension off each wire. Either
wire can be attached to either coil tower.
Step 5
Estimate how much excess wire should be cut from the
unterminated end. (Fig. A)
Step 6
Slide coil boot onto spark plug wire. (Fig. B)
Step 7
Strip 1/2” of insulation away from the spark plug wire conductor
core. Be very careful not to cut or nick the conductor core when
stripping away. (Fig. C)
Step 8
Fold conductor core back along wire. (Fig. D)
Step 9
Put coil terminal over conductor and crimp into place. (Fig. E)
Step 10
Apply a light coat of high dielectric lube (enclosed) to the inside
of the straight coil end boots and the angled spark plug boots
before they are installed. This prevents possible voltage leakage
around the boots.
Step 11
With the coil and wires mounted, be sure coil towers are
adjusted to insure maximum frame or tank clearance and
tighten clamps firmly. After use, check and retighten clamps
to insure coil is secure. We suggest using Loctite on the
clamp nut threads and checked periodically.
Step 12
We also suggest that spark plug readings be taken and that
carburetion jetting be checked after installation.
