Ground lead on tilt trim?

[keithm1961]

I was wondering if the wire lead from the port side is some kind of safety cutout to keep the engine from starting if the angle is to high.

The reason I ask is the engine strted fine at home, I took it to the lake where I had it tilted up and it wouldnt start, I brought it home with it not tilted and it started right up.
