Youre resetting BMS?

 

[Jakewallice]

Yes tried reset it multiple times

Have you tested the alternator?

Make sure nuts on all the power cables going to the positive fuselink panel on top of the battery are all tight.

Have you tested the alternator?

That is next

You can try pulling the cable from the BMS sensor on the negative terminal cable. That will make the alternator charge the battery without BMS interference. If the voltage is still low, then could definitely be the alternator if not a connection or grounding issue.

There is a chance the new battery could be bad. does happen.
