2009 05 25 - Received the GRT current sensor. Installed and it works but needs some calibration. At least the battery is charging now. Did some static testing and could not get more than 4350 RPM & 26.5 in MP. This had us baffled for several days. Tried other pitch settings on the prop. No luck. Finally, almost by accident, discovered that the port throttle cable was hanging up. Starboard throttle would go to full, port only about half. Surprising thing was that the engine was quite smooth. Never thought about carb imbalance. Anyway, here I'm resetting the prop to 21 degrees again before more testing.
