Pick up Coil on Mag
 

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
