My engine continues to run even when I shut down the panel. I turn off my master power switch and avionics entirely and the engine runs without a hickup. The only means of shutting my engine down is to starve it of fuel or shut down both lanes. Go figure. My fuel pumps aren't on the VPX either.

    That's interesting Eddie, I didn't know the pumps and engine in some way wouldn't be ran through the VPX. So they are all just fused?

    Not trying to hijack this thread but like Harlan, I am also interested in the VPX. For those who have installed the system, did you purchase the complete wire/connector kit or just the connector kit or neither? Thanks.

    Hey Eddie (et al) - Re: "I turn off my master power switch and avionics entirely and the engine runs without a hickup."

    Somewhere in the stack of material that either came with the engine or in a SI, SB, or SL I came across a note that said "Don't turn off the master switch with the engine running." Maybe the power supply system is different in the iS but your note made me think of it and I thought/hope it doesn't hurt to mention it.

    Thanks for that. Although I have no real reason for turning it off, I will do some searching. I just happened to discover it when I was trying to reboot the G3X and I tried the master switch. Im curious now.

    Isn't that what you want it to do?
