Installing the hot spark electronic ignition conversion kit in bosch distributors applies to red hot spark 3 series ignition kits warning.

Bosch ignition coil internal wiring diagram. The hot spark module s red wire connects to positive or 15 on bosch coil. All bosch ignition coils are built to achieve or exceed oe specifications and are known industry wide for their reliability and performance. Reversing the red and black ignition wires will destroy the ignition module. No spark poor spark or performance.

The resistor shown above is found on the factory ignition module you will have to desolder it from there and connect it to your new wiring. Older model cars used the 12 volt ignition coils to provide power to the spark plugs. Troubles with your motorcycles ignition. These coils had very simple wiring.

They usually required only three wires. You can change those settings at any time. Bosch ignition coils convert low voltage into high ignition system voltage creating an electric spark sent to the spark plugs which ignites the fuel. Bosch 0 221 119 030 bosch red coil brazil 1 6 ω to 1 8 ω primary resistance ok for 8 cylinder ignition kits not enough primary resistance for 4.

If you bought a new module it will come with a sachet of heat conductive paste be sure to spread this over the entire bottom surface of the module. Bosch ignition coil packs feature a sturdy design as well as excellent mechanical stability corrosion protection scalable spark energy for an improved fuel economy. Install a 1 4 ω or so external ballast resistor between the coil s terminal and the red hotspark ignition module s red wire if the coil s primary resistance is questionable or borderline. Terminaldefinition ignition coil 1 low voltage 4 high voltage 4a from ignition coil i terminal 4 4b from ignition coil ii terminal 4 15 switched positive after battery ignition switch output 15a output at the series resistor to the ignition coil and to the starter glow plug and starter switch 17 start.

The spark plug wire the power wire and the ignition switch wire. Here is how to test the ignition magneto coils found on all types of motorcycle engines points or cdi.
