A new CDi unit is only one part of the ignition system, so if a brand new ‘plug-in’ CDi unit does not fix, or changes the symptoms then your next action is to consider other parts in the system that may need to be replaced or repaired to clear the problem, especially where that system is over 20 years old. You can be sure that the issue will be found in an old part you have not yet replaced.
Our technicians have worked with, studied and manufactured ignition systems for over a decade and now we have published a guide detailing how to troubleshoot and overhaul ageing CDi ignitions that no longer work as they should. This publication is available free of charge on our technical support page.
