This would leave the left mag in operation and the right grounded.. The opposite is true when the switch reads right. This is true of the Bendix type GN that I have run into most often. The switch plate reads OFF---R---L---BOTH in that order. On our small Continentals, this makes troubleshooting a mag drop caused by a bad plug simple. A drop on the left is caused by the lower plugs, and the right will be the upper plugs. OH OH!! Now for some real confusion----the print in the Ercoupe manual shows the right mag wired to the L terminal on the switch and vis-versa Perhaps is someone has an ORIGINAL 1946 switch they'd be kind enough to check with an ohmmeter and see just what the contact development is and what letter terminal is grounded with the switch in each position. Perhaps the labeling on the print refers to what the switch plate says and not the terminal labels. If there is a change that exists in switch labeling, then I can see how confusion can exist. I was absolutely NOT confused until I looked at the original Ercoupe wiring diagram--now I'm not so certain. <G> Cheers: Paul NC2273H ========================================================================== ==== To leave this forum go to: http://ercoupers.com/lists.htm Search the archives on http://escribe.com/aviation/coupers-tech/
