Honda CB750 K2 - Primary ignition circuit upgrade with new relay Ep. 8

On the old Japanese motorcycles the current for the ignition system (coils) runs through both the main ignition switch (key) & also the kill switch - not ideal & will, over time, cause damage to the internal contacts to to arcing etc. So, as part of the ignition system upgrade on this old Honda CB750 we are going to make a number upgrades, & the fitting of an ignition system relay is just one of them....

The video shows a step by step process of installing a relay into the wiring system of the motorcycle together with a detailed explanation of how to wire up the 4 pin relay & the fitting of each of the wires onto the motorcycle.

In the next video we will be fitting the new Dyna Ignition coils!!
