Symptoms:
General system malfunction suspected to be caused by a faulty Battery Block.
Troubleshooting Steps:
Connect the batteries, one at a time, to the trunk harness from the top-down. Check the app/Grafana for faults on the newly connected BB before plugging in more batteries.
Note: If you do not want to do this top-down connection process then you have to use up to three loopback plugs on the trunk harness to maintain battery communications. Using the top-down method removes the need for the loop-back plug.
Turn the rotary switch OFF.
Disconnect all BBs from the trunk harness.
The first BB connected to the trunk harness needs to be the top BB, closest to the INV.
Turn the rotary switch ON and observe if the system goes active.
If Yes: Connect the next block in sequence to the trunk harness.
If No: The recently connected BB is faulting and preventing normal system operation.
Repeat this process until all four BBs have been checked for faults.
