This is my Dad's old timing light. I found it in an old toolbox. I remember using it and want to test it to see if it works. I know you put it in series with the spark plug in No 1 cyl. My concern is if I put it on a modern car (my 05 TB for example) will it damage the TB and is the voltage too high for the light possibly causing damage to the light?

Since the TB has a coil pack above the spark plug, you would be hard pressed to be able to connect this tool. Anyway, you can't adjust the timing on these (or any modern engine), the timing is controlled by the computer.

You missed the point. I don't want to use it on my TB. I'm trying to figure out a way to see if it works.
