Hello,

I checked the specs for the 1989 300e/ce and they say that the HT voltage varies between 6-16kvolts. However in another area where they discuss the testing of the ignition, it says the specs are 8kv and 20kv? Also there should not be a variance between cyl of more 3kv. Something I didn't relealise is, as the rpm is increased so does the HT power. In other words at idle its quite a bit lower then at 3000rpm. Consequently all your HT wires, plugs, cap, coil and rotor are not in good working condition then you may get missing at idle because of the much lower voltage available.

I always assumed the voltage was constant?

Comments please
