Simple question:
I will shortly be replacing only the right Slick mag on my O-360-A1A with a P-114 PMag (v.40). I will then have one Slick IC mag and one PMag. The p-leads from both existing Slick mags go to the respective L&R terminals on a single keyed ignition switch, with wires from each L&R terminal routed to a Horizon P-1000 tach. The input signal voltage for the tach is 100-1000 vac. Will the p-lead signal from the PMag support my Horizon P-1000 tach? Or is some kind of signal conditioner required? I could not find the voltage/freq characteristics for the PMag p-lead in the installation manual to do the comparison myself.
Another question:
I see that some users install a flow restrictor (snubber) in the MAP line to the PMag. EMag also recommends this be installed. Can anyone recommend what make/size restrictor and how best to do this? Is there an Aircraft Spruce (or other) part number for the restrictor?
I'm not the original builder but wish to help guide the workshop doing these mods.
