Hi Dave,

No I haven't measured the current, I'm going off of Thomas's article that he posted above.

Thomas's report;

"The ignition coil BERU ZS-109 can be used, see the following explanations, even if a longer ignition spark (120 µs instead of 27 µs)
occurs here with a lower combustion current due to the principle. Engine test bench tests with overhauled original engines
and engines with moderate performance have not revealed any differences in the running behavior of the engines. Unfortunately,
this coil is no longer produced."

It appears he didn't actually do a measurement, which reduces the credibility of the report.
