I have a set of Bendix 1200 magnetos I'm wiring up to my ACS ignition switch. I used 18 ga shielded wire between the post on the Mags and the starter switch. I followed the ACS and VPX instructions which had me connect the shielding to the ACS switch ground. So the shielding is grounded no matter what.
On the Bendix side I just crimped on connectors which I'm guessing crimped the shielding in with the wire, because no matter what the switch position is measuring from the connected posts they're both showing grounded. Easy fix but wanted to ensure I'm wiring the Bendix side correctly before I push on.
My assumption is I don't ground the shielding on the Bendix side. So do I just need to strip the wiring enough that no shielding will get crimped in with the connector? Then do I just connect to the post on the back of the magneto?
To test I want to make sure I'm crystal clear on what should be expected with the ACS in the various positions and measuring between the connected magneto post and the airframe.
Off - Both mags should be grounded
Left - The left mag should show open and the right grounded
Right - The right mag should show open and the left grounded
Both - All mags should show open
Start - Left mag open and right grounded
