I don't understand why you consider this a problem. Assuming that the engine has already started running and the starter switch has been released, if the starter run down is generating enough electricity to continue to fully activate the SlickStart then you will just have retarded ignition from the left mag for that brief period of time. What is the harm in that? 2) Realize that Slick SB1-06A calls for disconnection of the SS unit from the right magneto and removal of pin #2 on SS1001 SlickStart ignition boosters. This is the pin and wiring that would automatically ground out the right magneto during SS unit activation to avoid the possibility of an advanced spark coming from the right magneto. 3) SB1-06A was created because Unison felt that this connection "potentially compromises the redundancy of the ignition system." I understand that Unison is working on an updated version of the SlickStart. 4) Once SB1-06A is complied with your customer should realize that grounding out the right magneto by having that magneto switched OFF during cranking is the only sure way to ensure that he will not get advanced sparking from the right magneto. 'OC' Says: "The best investment we can make is the effort to gather and understand knowledge." PS: I hope that Bob Nuckolls or other expert can comment on the rationale behind this statement: "17.Use either a varistor, or a diode plus Zener diode as a protective circuit against reverse surge in the G9EB relay coil. Using a diode alone will reduce the switching characteristics." It came from the Precautions sheet from this web site: http://www.omron.com/ecb/products/pdf/en_g9ea_ec.pdf Thanks ------------------------------------------------------ Time: 03:28:45 PM PST US From: "Dave Saylor" Subject: AeroElectric-List: Slick Start Bob, I'm installing a SlickStart (SS) on a left retard breaker mag, no impulse couplings. We're using two locking mag switches. Customer wants to leave the right mag off for starting without the interlock to the left switch you describe. Powering the SS via the push to start is contrary to the instructions, which have it powered from the starter feed. Problem is, I worry that the starter might generate power while spinning down, thus keeping power to the SS after the start switch is released. If I power the SlickStart from the push to start switch, is there any chance I will damage it from high voltage due to the collapsing contactor coil? The coil has a surge diode installed.

The bent whip is removable and I have a second attaching plate over the doubler plate that allows me to cover the hole. I think Bob has posted photos of my Comant installation somewhere?! If not - zap me direct.... -----Original Message----- >From: Emrath >Sent: Jul 30, 2007 10:17 PM >To: aeroelectric-list@matronics.com >Subject: AeroElectric-List: Com Antenna > > >What are folks using for Com Antennas?
