1970 GTO Version 2.0

I'm not an Electrical engineer, but I did some Googling and found these links. The first one makes it seem pretty easy in theory.

I guess the purpose is to limit the current through the circuit. One site says that the most common sizes for logic circuits are 10K ohm or 47K ohm.

It looks like the resistor just goes in the tach signal line??????????

Good Luck - I'm looking forward to learning something here. If you don't figure anything by the first of the week - I'll be seeing a buddy of mine who is an EE on Monday, so I can ask him.

Keep up the good work!
