Your technical analysis is spot on.
After a couple of false starts (or rather stops) in Mali where recharging the battery and redoing the battery connection seemed to solve the problem, I had a total loss of electrickery in the scenic Casamance area if Senegal.
The scene of my enforced stop in Lakeland:
I managed to get a local mechanic out from the nearest village on the back of a mototaxi.
Pretty quickly we traced it to a faulty connection under the fuel tank, as you suggested. I wished I had brought connection cleaner spray that was sitting in my garage.
However the Senegalese mechanic managed to bridge the gap with some wire within the connector, and suddenly all systems were go again
.
Bike now safely tucked away in The Gambia until I return next month for another Senegal foray.
