I followed the Bob Nuckolls approach and I don't recall him mentioning these things. I have no radio interference issues from engine noise. For the mags, I grounded the shield wire to the closest bolt. I believe I used bolts that hold the rear engine case on, but unfortunately, I do not have any pictures showing this detail. -------- David Gallagher 601 XL/Jabiru 3300 First flight 7/24/08 Upgraded 3/19/10 150+ hours and climbing!

Apparently the ferrite suppressors are marginally good for RF static from what others have told me. Grounding on the engine block has been suggested several times...

From: "jetboy" I don't wish to over-analyze your schematic, however there are some features that need clarity; The alternator contactor, rel.3 does not disconnect the AC from the regulator. If the alternator contactor is open, depending upon the DC bus voltage at the time, the voltage applied to your capacitor will be more than 40 Volts, and it might not do nice things to your equipment when the contacts close. Jabiru manual states the regulator output and sense wires should be tied together at all times, to prevent this possibility. Think what might happen if you open the master switch, and the main contactor is open, and there is more than 6 volts difference between the batt volts and the DC bus volts. Will Rel.3 coil be energised via rel.1 coil and the battery connection? do you want this to happen? The placement of the OVM crowbar module does not look appropriate to me. I prefer either of 2 published wiring systems; the Jabiru way or the Aerolectric way, both are acceptable practice for homebuilt aircraft, its when a hybrid system is attempted that unexpected consequences could result.
