Matt's RV-7 Project

More splicing, crimping, soldering, et cetera. This photo shows the wiring for the tach sender and fuel flow transducer:

I also finally got around to uploading a new copy of my electrical system schematic:

Finally, a warm weekend! After taking care of yard work and bills and house maintenance, I still had an entire afternoon to spend in the garage. I did a bunch of cleaning and straightening up, and then finished the last of the wires that runs to the lower connector on the GSU 73 ADC/AHRS/EIS unit. The upper connector is for all the various engine sensor inputs, which I'll begin hooking up soon enough.

Some of these connections need to be spliced six ways to sunday, and you have no choice but to do it right there on the airplane. A helping hand tool is indeed quite helpful for this. Note the heavy heatshrink on the jaws to protect the wires.
