Brief Description:  Finalizing wirebooks and panel work

Well it's been a long time since I've put anything in here. I have worked on the aircraft in one way, shape, or form over the last several monts but haven't been posting it to the log. I probably put around 40 hours into doing the wirebooks for the panel and VP200 and I think I have it finalized now. Still going back and forth on how best to deal with the LSE ignition power but that will shake out soon. In the mean time I mounted the two guarded switches I got for the ignitions. I'll either use these in conjunction with one VP power source and one direct battery power source or I'll use only direct batteries to a switch breaker. One of the potential issues that was discovered a year ago or so was that the LSE's have a built in crowbar circuit. The problem with this is that if you run power directly from the batteries in back, via a fuse, and the crowbar trips it will blow the fuse. While this is apparently extremely rare it has the potential to shut down the ignitions. A resettable breaker at least allows you to reset after the event but it would need to be in back by the batteries. The original solution I came up with was a combination of 15amp CB and a 7.5amp switch breaker. After putting them in series, the 7.5 would trip everytime if I shorted the connection and the 15amp stayed engaged. this would allow a 15amp breaker to protect the wire back by the battery but then use the 7.5 switch as the power switch and still have the ability to reset in the event of a crowbar or other trip. I could also use a combination of this with power from the VP and eliminate the two switches in the picture abov.
