There are different possibilities to dodge this problem :
(1) Install your system under the dashboard
(2) Spray a non-conductive protective varnisch (available in every retail shop) on the whole system, of which
a "Thick" layer must be applied on the components and the circuit side. Once this layer is dried, a second
layer may be sprayed. The ignition system may be fixed under the engine canopy.
(3) Build the system into a box well closed, but the heatsink has to be well ventilated. Don't use a
plastic bag or another similar material as fixed around the PCB.
(4) Insulate the entire ignition system with resin (also available in retail shops) but do not insulate the heatsink
which has to be ventilated.
The heatsink must be contact free from the frame (earth) of your car. The two holes of the heatsink are
used as fixing holes. Utilize small screws or Parker-screws. Ensure that the PCB has no contact with the
metal part of your vehicle.
Disconnect the lead going from the coil to the breakers points, and disconnect also the condenser.
Follow the instructions on the figure for all connections. Connection 1 of the PCB goes to the + 12V com-
ing from the ignition key. This "+ 12V" is also at the PLUS of the coil. If a ballast resistor is used, the con-
nection must be made in front of this resistor.
Connection 2 of the PCB goes to the breakers (do not forget to disconnect the condenser on one side).
Connection 3 goes to the connection of the coil, which was previously connected to the breakers.
And now connection 4 goes to the frame (earth) of the car, thus to the MINUS of the battery.
