Remove the points and condenser along with its wiring from vehicle. Connect any
other wires to the coil in their original positions. The Simon BBC module is
designed for 12V negative ground applications only.
If you can't get the ignition to work once installed, try these suggestions:
Check the wiring:
1. Condenser and wires from distributor should not be installed in vehicle once
the kit is in place
2. Check the coil resistance prior to fitting this unit to ensure that your coil
has a resistance of more than 1.5 ohms and remove any ballast resistor present
in your vehicle
3. Connect the Black wire to the coil negative ( -ve or 1) terminal.
4. Connect the
Red
wire to the coil positive ( + or 15) terminal.
5. For testing purposes, no other wires should be attached to the coil
terminals, except for the center high-tension lead to the distributor cap.
Timing:
You can set the timing dynamic with a strobe light with points ( engine running
) and with electronic system you can do the same.
You can set the timing approx as before static, and you will need a strobe light
ie + and –ve to strobe and sensor lead to No1 plug lead to set the timing
dynamic and then adjust to max @ 3500 rpm say 24 degree (depends on the vehicle
and engine).
The electronic ignition module is mounted as near as possible to the same
position as the points were, but in some cases the distributor will possibly
have to be turned +/- 10 degrees from where it was with points. Setting the
timing is recommended once you have fitted one of our electronic kits. Setting
by dynamic is the best and most accurate way to adjust the timing.
Battery voltage to coil:
With ignition switch ON, engine not running, check voltage at coil + terminal.
The voltmeter should read somewhere around +11 to +14 volts. If voltage is too
low or there’s no reading, the battery terminal or ground connection may be
corroded and need cleaning or the battery may need charging. Some vehicles have
a resistor wire running from the ignition switch to the coil +ve terminal. This
resistor wire drops the voltage below 9 volts so you may need to run a
non-resistor wire from the ignition switch to the coil + terminal or run a +12V
wire directly from the ignition switch to the red wire of the Simonbbc ignition
module. Make sure that the ignition switch terminal to which you connect this
wire has power only when the ignition switch is in the ON position. Or you can,
for temporary testing purposes only, run a wire directly from the battery's +
terminal to the coil + terminal, the Simonbbc ignition red wire to the coil +
terminal and the black wire to the coil -ve terminal. Do not leave the wire
from the battery connected to the coil + terminal for more than a minute or so
without the engine running
Jump-starting the vehicle:
Simonbbc recommend using caution when jump-starting the vehicle fitted with our
electronic kit. Connect the battery's + terminal to the other vehicle's battery
+ terminal. Connect the negative (black) part of the jumper cable to engine
ground points, such as a bolt on the engine block, on both vehicles.
Do not turn the ignition switch to the ON position while the vehicle at the
other end of the jumper cables is running. Charge your vehicle battery with the
other vehicle or with a battery charger and then remove the jumper cables or
charger before turning on the ignition switch and starting your vehicle. If the
ignition switch is in the ON position while both vehicles are running, the
electrical surge resulting from both vehicles' charging systems being connected
together with jumper cables could be enough to destroy the ignition module
and/or other any electronic components.
Gap between the black trigger and the ignition module:
If you need to increase the air gap slightly, hold ignition base plate away from
distributor shaft while tightening set screw and/or loosen the two screws and
retighten screws while lightly prying ignition module away from magnet sleeve.
Do not over-torque the screws. The black magnet sleeve should not rub against
red ignition module, but exact gap is not critical. It may be necessary to
gently pry red ignition module away from black magnet sleeve to keep them from
rubbing together.
Coil:
Standard Lucas or Bosch coil or one of our standard points type coils is
recommended. The Simonbbc module red wire connects to positive ( + or 15 on
Bosch coil). The black wire connects to negative ( –ve or 1 on Bosch coil). The
coil should have a minimum of 1.5 Ohms internal, primary resistance.
To measure primary resistance: Label and remove all wires to coil. Using a
digital multimeter in the 200 Ω mode, measure between coil’s + and - terminals.
Allow a few seconds for the reading to settle.
For best performance, the coil should have a minimum of 7,000 Ohms secondary
resistance (measured from coil’s + or – terminal to center high tension
terminal, in the 20K Ω mode of the Ohmmeter)
Vehicle System Voltage:
If the charging system voltage, measured at the coil’s positive terminal, is
more than 14.2 volts at
2,500+ RPM, the voltage regulator may need replacing. Too much voltage can
damage the ignition module and other electronic components. A maximum charging
system voltage of 13.5 volts is adequate
Warning:
Reversing the red and black ignition wires will destroy the ignition module and
void the warranty.
Using a coil with too little primary resistance can cause the ignition module to
overheat and fail, thus voiding the warranty.
