Old SW tachs
 

Do most or all of the older tach..mid 60"s use a sender??or are some of them direct wire to the coil??..have a line on a old SW greenline..does not come with a sender, and no I dont have a model number....yet!. Thanks

Most use a sender, some do not. If its the "Yenko" pedestal type, then it needs a 990B sender. They can also be converted to solid state, which is probably the smartest thing to do regardless, as the senders were not the picture of reliability.

There are two models of the greenline pedestal. They both look the same externally. One uses a sender and one does not. It you take the rear cover off is it easy to tell. The transistorized tach(no sender required) has 3 pins labeled 4, 6, and 8. There is a wire that can be moved between the 3 posts to select the cylinders.

Interesting. I've never seen an original SW greenline 970 pedestal tach that didn't require a sender.
