Rotax 915is and VPX installation discussion

[VictorV]

Does anyone know how I can determine exactly what type of signal the 915is Lane A and B switches generate? It's just
connected between 2 pins on an engine connectors HIC-A and HIC-B. Is 1 pin ground and the switch just connects the other pin to ground
or is there power on one side and switch connects power to the other pin?

Eric, you implied that it's the former but is there a way to verify this? Maybe someone that has a 912is or 15is can measure
what's happening on their system.

Victor - I think Eric was taking your original drawing at face value where you show one side of the Lane switch to be a ground. What Eric stated was correct for an electrical circuit based on what's on the drawing. You are right to try and figure out what Mother Rotax is doing for real since the Lane switch is nothing more than completing continuity between those two pins on HIC a and B.

Since I am going to use a 912is and the VPX I am watching this with a lot of interest.
