Hi, thank you for the comments on the differences between the 230ET and 230FT control boxes - I was looking for the Ignition Control Box! I've been working outwards from the non-sparking plugs and am happy with the coil - the distributor and rotor arm - and the TDC/rotation output. But there my knowledge and testing have hit a brick wall. I have run all the 'Haynes' tests (from page 157/158) and they seem OK. What I can't resolve is which of those tests actually prove the ignition amplification that pushes a decent VAC through to the coil primary wiring - which clearly I am not getting. One flow chart I have followed says that the Power Stage is the culprit. But the Power Stage in our cars seems only to cover the fuel injectors? Just wondered if you had any thoughts?
