Greg has had my tach for half a year or more, and I still don't have it back. Every time I call, he has some excuse. I ended up buying another one from Truck/Car Shop. So good luck with that Greg thing!

By the way. Some people think that the Chinese external voltage regulators cause voltage spikes, enough to damage the resistor. Remember, the wire going to the HEI is a ground wire. No energy comes to the tach from the HEI. The voltage issue is on the alternator side of the equation. FYI, I also converted to an internally regulated 12SI.
