I went through the radio gear still in the wreckage on my bench very thoroughly today. I turned everything on and began wiggling wires and connections. All at once the Orange LED on my receiver flickered out! The problem was located in a brand new 25.00 MPI switch with LED voltage monitoring, and charge jack. The brown wire (negative side) pin connector was not fully seated into the connector plug socket during factory assembly! This meant the pin was too short to make good contact with my battery connector, even when tightly held together with a safety connector clip that was holding them together! As you tap the connection with your finger, you can see the receiver turn off, and stay off till you tap it again! So not just a quick brown out, but a prolonged disconnection, preventing the system from rebooting in a second or two that would have regained control. I am relieved to find the cause of this 1500.00 crash.
