Is there a tach output on the MSD Ignition?
Is there a tach output on the MSD Ignition?
If you have any questions concerning coils, contact our Customer Service Department at (915) 855-7123. TACHOMETERS The MSD Ignition features a Tach Output Terminal on the side of the unit. This terminal provides a trigger signal for tachometers, a shift light or other add-on rpm activated devices.
Can a GM part number be replaced on a tachometer?
The tachometer system uses a National Semiconductor LM181 with a GM part number on it. if your tach is completely dead you can replace this chip with the NTE01670 as the LM181 is no longer manufactured. this is the other chip that is completely black.
What kind of circuit board does a tachometer use?
there are a few nuts under the circuit “board” that require you to carefully lift it up to get at them. Now you’ve got your tach to where you can work on it! The tachometer system uses a National Semiconductor LM181 with a GM part number on it.
Where do you plug shift light into tachometer?
For external Shift-Lite models, plug shift light into tachometer connector. Plug 7is directional, do not force fit! 5) Recommended placement of external Shift-Lite (if applicable) is at 10 o’clock position. it is possible to place Shift-Lite in other positions in accordance with driver preference and 6)vehicle 5)mounting requirements.

Is the MSD 6 series an inductive or capacitive ignition?
The MSD 6 Series Ignitions feature a capacitive discharge ignition design. The majority of stock ignition systems are inductive ignitions. In an inductive ignition, the coil must store and step up the voltage to maximum strength in between each firing.
What is part 8910 on a Ford tach?
It specifies, the part #8910 is designed for non-current limiting (originally equipped with a ballest resistor) such as breaker points or optical triggered distributors. The tech guy you talked to is WRONG, WRONG, WRONG. If you’d like to call, my number is 918-655-3352. I have this application on six Ford factory tach cars and all work properly.
