Finally got my "A" engine from the engine guy and it is beautiful. Can't waitto get it mounted.Everything I've read (Bingelas, etc) says that the mags should be grounded andthey have a grounding screw, but I'm not sure why since the mag body is positivelygrounded to the engine already. Am I missing something? do I still needto ground them with a wire to some bolt?________________________________________________________________________________

You will need to run a ground to the mag switch to make it work. Also, you willwant to ground to bond to your VHF and it is recommended that you have a groundplate somewhere. My plane has an aluminum access plate on the underside behindthe rear cockpit Fuel tank is also grounded.Dick N. ----- Original Message -----
