Group:

I have a quick question regarding how the mags are wired to toggle switches as illustrated in drawing Z-11.

As wired in this schematic, if you place the right mag to "on" and then engage the starter via the left mag/start switch, does this ground out both mags so that you can turn the engine over with the ignition essentially off?

Thanks in advance

Hello Jeff, The way I interpret the drawing is that when the right mag is "on", the starter circuit is disabled. In other words, when the right mag is on (disconnecting 2 from 3), continuity between terminals 5 and 6 is broken, which disables the starter circuit. The drawing shows the right mag switch in the OFF-START position. With the switch selected as drawn, the right mag is grounded out (disabled) via continuity between terminals 2 and 3. The drawing shows the left mag grounded out (disabled) via terminals 2 and 3. The drawing shows the starter circuit is disabled because terminals 4 and 5 on the left mag aren't connected. As drawn, if the left mag switch is moved, the left mag is disabled. If it is moved to its full opposite position, the left mag is enabled (no continuity between 2 and 3), and the starter is enabled (continuity between 4 and 5). I hope that helps..

Thanks Matt.

I guess what I really want to know is how do you turn an engine over as

wired in Z11 without the mags hot?

Without adding jumpers, or more switches, it won't happen.. In order to

engage the starter, the left mag switch will have terminals 1 and 2

connected, which will enable the left magneto (because terminal 1 isn't

connected to anything). For diagnostic purposes, you could connect

terminal 1 to ground. Then the left mag would be disabled.
