I just purchased and received an EI tachometer (P/N R-1-4L2). The unit came with 2 pairs of "RPM isolators" to be installed on the back of the mag switch.
According the to instructions, one pair or both pairs may be required to provide a steady tach reading, depending upon the type of mags in use.
In my -4, I am running a pair of PMags, can anyone who has installed this system in their aircraft (with PMags) tell me whether one or both sets of isolators was required?
Thanks in advance,
