Pick up Coil on Mag

[hharney]

Is anyone familiar with the tach pick up coil on the mag of the C336? Part number or any info would be appreciated

Is the number a S1512-2 which is now 10-187065-1?????

$659 at yingling but not sure this is the right unit

I'm bumping this old thread since we have a dead tach on the front engine that I need to troubleshoot.

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 ?

Thanks!

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
