What is the most likely cause and can I assume that it is indeed a magnetic coil that sends the signal to the gauge and NOT a breaker unit as suggested in the SM ?

Swap the wires on the gauges to test if the gauge is bad Most likely the pick up coil or broken wire I just replaced the one on my rear engine
