Ultegra DI2 Dead after shipping?

Hey. I am on a trip and shipped my bike. When I arrived and put my bike together the DI2 is totally dead. I can't get a status of the battery, no lights. . .I took the seat tube off and checked that the cable was connected to the seat tube batter and it was. I tried plugging it into the charger and nothing. . no lights on the charger.

Any ideas?

You shipped a bike...have you verified all the connectors are seated?

Which charger and which Di2 system?

Being that you said you checked the seat tube for the battery connection, I'm going to assume you have an internally routed frame? You may need to pull the cranks to check the B junction in the bottom bracket area. I'm willing to bet that a wire came loose there, since it is between the battery (definitely connected) and the A junction.

My SMBCR-2 charger has no lights when plugged into a USB wall adapter, and not attached to the bike.

Troubleshooting
More details, please.

This is the internal battery mounted inside the seatpost?

Did you remove the seatpost and unplug the battery when the bike was boxed for shipping? If not, it's odd that the internal wiring would be affected. It's not going to get any more stress than hitting a pothole while riding.

Did you remove the stem or bars to pack the bike? Unplug any cables to the junction box under the stem?

The small plastic Di2 cable tool helps to pull and to seat the plugs, which have to go in with a definite "click"

To answer the questions...

I have checked all the connections that are visible...handlebars and fron and rear derailleur

Ultegra di2 6870 and the charger that came with it

It is internally routed

The seat was removed and wire disconnected. The handlebar was removed but not disconnected.

Thanks

Possibly a shifter got pushed and set a derailleur into a shift position when the chain couldn’t move. The derailer will keep trying and run the battery down. So likely a dead battery. Try a charge for a while, maybe it’ll come back.

I’ve read to disconnect the battery prior to long distance trips.

I have that charger. The light goes out when it is charged. There is also an error status light, so if something is wrong, it flashes. So if you saw nothing, presumably your battery is charged and healthy.

Well, actually... I'm pretty sure hitting potholes doesn't involve large doses of cosmic radiation.

It seems like a pretty unlikely scenario, but I'd say it's definitely a possibility.
