Obviously take the keys out of the ignition when you do this - if you're feeling particulary diligent disconnect the battery. One precaution that may be worth taking: if the new DI cardtridge has been stored on its side or upside down, allow it to stand for ~15 minutes after fitting it but before starting the car to allow the oil in the coils to settle. I recall reading somewhere that the transformer oil used in the coils is rather viscous. I don't know how careful you have to be in that regard and this advice may apply only to the older cartridges with individually replaceable coils. Either way, a 15 minute wait is cheap insurance against burning out the coils in a new DI cassette. A common failure for the newer DI cassettes is a in an intermediate 400 volt step-up stage, whereas the older cassettes tended to suffer more from burnt out individual HT coils. AndyH '94 9000 CDE
