Skyview A/P - Pitch will only climb

[dgamble]

I have a Skyview installed in an RV-12. For the last 15 hours, the autopilot has work perfectly. Today, however, it refused to hold altitude or descend. The servo was engaged; I could feel the clutch slip and received the 'slip' annunciation on the display when I overrode it.

Once on the ground, I tested it again. No matter where I put the altitude bug, it just kept pulling into a climb. Disconnect worked fine.

I'm wondering if anyone can provide me with a troubleshooting plan. Is this more likely to be something happening in the wiring, the servo, or the Skyview?

This can happen if the G-meter in SkyView is reading wrong, and thus the AP is trying to fix the G's it thinks are wrong.

What is the G-meter in SkyView reading on the ground?

It read 1.0, but when I tested the autopilot again it worked fine. If it acts up again, I will be sure to to get the G-reading.
