'm wondering if each tach is tuned differently and hence this resistor is different for each tach.(?) I found only this resistor to be the problem in my case. You may wish to troubleshoot as I did. Get a potentiometer (1k ohm I believe) and connect it in place of the fried resistor using alligator clips. With the car running and everything connected, turn the potentiometer down slowly, decreasing resistance from 1k ohms until the tach comes to life. Shut it down, disassemble, and read the resistance of the potentiometer. (you could also keep the pot in there if small enough to fit in the can. Super glue the shaft to keep it from rotating.)
