Thanks for the tip Barney, but it does not apply to this car.
BTW I have seen (electronic) tachometers go bad and kill the engine about 4 times on various cars

Later model MGB have ballasted ignition with a 1.5 ohm coil and a 1.5 ohmballast resistor.  The third wire goes to the starter solenoid, sothe starter can bypass the ballast resistor and switch full batteryvoltage onto the coil during crank starting.

Thanks Barney, but I have 3wires on the distributor side, one to the points, and the terminal thatgoes to the tachometer has a double wire connection, so 1 to the points,1 to the tachometer, where does the other one go to, or do they both goto the tachometer?

Two W/B wires there on one terminal, one from coil "-" todistributor, and one from coil "-" to tachometer.
