How is the tachometer on a Datsun 1200 wired?
Voltage signal wiring. The tachometer wire is connected to the ‘-‘ terminal of the coil (e.g. to the points). This is what later 1200s and most aftermarket tachometers use. Simply wire this in without changing/cutting the existing wiring. The early Datsun 1200 tachometer is wired differently than most tachos because it uses induction signal.
Can a faulty tachometer cause the ignition to fail?
So anything connected to the coil wiring (such as anti-diesel valve) may make the tachometer read incorrectly (bouncing needle). The good news is that a failing tacho of the current-sensing type will not cause the ignition to fail. Newer utes do not have the tacho wiring in the harness. 1.

How is a tachometer connected to a transformer?
This signal is indirectly wired to the tachometer via a transformer inside the tacho body. Also known as a current-sensing loop, inductive link, inductive coupling or impulse loop. This type works with standard points ignition or with electronic ignition, but not with multi-spark discharge ignitions. RG – lights (two lights, two wires.
