This LML list is a good thing.

Actually it had failed before takeoff but I was un= aware since the header tank was full on takeoff. I observed the sight gauge l= evel drop to its normal pump on level and kept falling.

The auto transfer system is controlled by a solid stat= e relay from Perhelion Design and it works great. > However, the system failed due to the fact that one of the leads to the re= lay from the buss had somehow slipped off its terminal on the relay(these te= rminals are pointed down in this installation). A female spade connector tha= t was obviously just loose enough to wiggle itself off, did so. In the end, a= simple fix but it reinforces the point that none of our building work shoul= d be taken for granted.
