Just behind my starter switch and master switch there is a potted block mounted to a piece of support structure. It is about .5" x .5" x 2" and is some sort of composite. 4 wires are in the block. The wires from the master switch split off and enter this block. the other two wires go from the block to the back of the starter switch. I don't see an item like this on any of my wiring diagrams. In the one image below the master switch was pulled through the panel, and you can see the wires going to the block. Anybody know what it might be? Aircraft is 1996 ish, an RV4.
Thanks
