Good C.O.P. / Bad C.O.P. - Advanced Ignition Diagnostics
Course number: TBD
Your customer’s ignition system is the ‘heartbeat’ of their engine. Are you the ‘heart doctor’ that you need to be to diagnose problems quickly and accurately? Your father’s ‘big box’ engine analyzer may be obsolete on vehicles with C.O.P. (Coil On Plug) ignition systems but the advanced diagnostics it provided in its day can be easily replicated with some practical methods you may be overlooking.
