Hi- This another question that relates to my topic below- "Two station Tachometer issues".

I went to buy a replacement tach this morning because of a HUGE closeout at the West Marine "surplus" store in Oakland. (I got a new $104 tach for $15).

Anyway, the instructions on some of the tachs I tooked at specifically say- "won't work with Thunderbolt I systems". Anyone know why?

Thanks,

Don
