It’s always electrical it seems nowadays on these electronics that manage everything. Glad you found it. I was driving a new truck about 25years ago, I turned the engine off and went to sleep, woke up, turned the ignition on NOTHING. Every nut on the batteries were maybe finger tight. Factory oversight. So I always like you do, go to the source. Thanks for sharing
Consider the power relay in the fusebox. I dont remember exactly what the name is but it has power in the desciption. After so many cycles the coils start to overheat and stays stuck. Also the fusebox screws needs spacers 1/8 is fine. After so many years of tension the green and yellow datalink wires going to all ecm's in that area start to give out. Luckily you got rolling again.
Unfortunately driver I had the same issue with my 2007 vnl780 and it came out to be the ECU. After replacing it works great. The issue is the that main engine harness gets oil in it that travels to the ECU and fries it. It gonna shut completely off and it won’t crank.
Man my damn volvo is doing this but my turns off and batteries light comes on I think is the damn ecu cable but ama check the fuse too and the cable of the fuse
First time I've ever seen one come loose. The battery got loose and was moving around. Some of the roads I go down make you think you're riding a rodeo bull with all the jerkin and bouncing. I've had a few cell phone holders and cup holders break off the dash before as well as some broken shock mounts and shock ends.
