Features & Specifications Even the most sceptical one has tot admit that the electronic ignition system has a great advantage over the conventional ignition system. Car constructors now mount such a new system on their most expensive models. THE ADVANTAGES ARE : Better ignition Less air pollution Gasoline economy Better running engine, especially at very high and very low speed Visible less wear of the breaking points, which means a constant calibrated state.
Assembly hints 1. Assembly (Skipping this can lead to troubles ! ) Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully. 1.1 Make sure you have the right tools: A good quality soldering iron (25-40W) with a small tip. Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the tip, to give it a wet look. This is called ‘thinning’ and will protect the tip, and enables you to make good connections.

Installing in the car 7. Installing in the car First of all, control the breaker points for a correct setting as per the constructors instructions, or better, use a new set of points, before installing the ignition system. The existing ignition condenser is to be disconnected. This is very important. This condenser may be inside or outside the distributor. ex.: On a 2 cylinders Citroën, this condenser is fitted to the breakers, thus unscrew the nut and remove out of the car.
Installing in the car 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.
Test & maintenance 8. Test The installation is now finished. Verify as follows : The condenser is disconnected (very important) All connections are well fixed No lead is misconnected or mixed with another. Now the engine may Start. 9. Maintenance The ignition system on itself does not require a maintenance. The ignition system maintains the breaker points in a good condition, so they will not be burned, as the bring only a few amount of current to the electric system.
