Unfortunately, as the Torker company is out of business, it may be difficult to find an official troubleshooting guide. However, here are some general steps that you can follow to replace the battery on an electric bike:

1. First, locate the battery on your Torker 400E bike. The battery is typically located on the frame of the bike, either under the seat or on the downtube.
2. Remove the battery from the bike by following the instructions provided in the owner's manual or by consulting a bike mechanic.
3. Check the voltage of the battery with a multimeter to determine if it is completely dead or if it can still be recharged.
4. If the battery is completely dead and cannot be recharged, purchase a new battery that is compatible with your Torker 400E bike. You can search for replacement batteries online or at a local bike shop.
5. Install the new battery into the bike by following the instructions provided in the owner's manual or by consulting a bike mechanic.
6. Charge the new battery fully before using it. You can use the charger that came with your Torker 400E bike or purchase a compatible charger if necessary.
7. Test the new battery by riding the bike and observing the performance. If you encounter any issues, consult a bike mechanic for further assistance.
