Looking for some feedback on the state of my ignition coils based on the videos below. I haven't bothered doing the resistance testing in the service manual because I've read multiple times that it is useless.

This is the first time I've used a high energy tester like this and I wasn't really sure what to set it to. I believe how I have it set is approx 30kV required. Also wasn't sure if I needed to actually start the engine, opted not to as I have hot start issues and also didn't want to flood it by going on and off all the time.

To me the spark looks very yellow which indicates weakness, but looking for some feedback.
